Visual controls

Dewesoft X allows you to set up different visual instruments for each input, for example digital meter, recorder, FFT analyser, etc. and arrange them freely in front of any graphic in your system to have a simple, but efficient overview of your measured signals.

NOTE: Primary goal of Dewesoft design online display screen is to create clear and intelligible appearance of acquired and calculated data in different instruments on screen for review and analysing of these data. Dewesoft X allows you to set up different instruments for each input, for example digital meter, recorder, FFT analyser,... and arrange them freely in front of any graphic in your system to have a simple, but efficient overview of your signals and measurement.

In Dewesoft X we know four basic types of visual controls:

- controls which show only one value (digital meter, bar meter, analog meter, indicator lamp)
- controls which typically show all the data (recorder, vertical recorder, xy recorder, GPS map)
- controls which show the part of data directly or calculated (scope, FFT, octave, vector scope, harmonic FFT, tabular display)
- additional visual controls like picture, text or lines

All controls can be combined on one single screen or we can build several screens for specific part of measurement. Dewesoft X has few pre-defined displays but these screens can be altered or custom displays can be created with different appearance. The picture below shows typical display with standard elements for designing the display.

Dewesoft X offers a variety of customizable visual options/controls to suit your needs.

You can set up different instruments for each input, for example digital meter, recorder, FFT analyser,... and arrange them freely (in front of any graphic) on your system to have a simple, but efficient overview of your signals and measurement.

To add an instrument to your display you need to go to Measure mode and select Design mode. Visual controls icons will appear on the screen. Click on desired icon to add the visual control to the current screen.

Most of the Visual controls are always visible in Design mode, but some of them that appear only when you install specific Plugin or enable some option, for example Power, CA, GPS...

Dewesoft X supports also Custom visual controls that can be downloaded from our Web page, for example Rotor Balancer, 3D polygon,...

In this course we will get to know all the available Visual controls and describe their corresponding Properties.

The DIGITAL METER is designed to show the current or averaged value of the channel.

The digital meter has only one appearance: the channel name and units are displayed at the top left, the display type at the top right side.The main space is used by the value letters itself.


When you select a digital meter in the design or run mode, the following distinct settings will appear on left and right part of the screen:

- Display type
- Display value
- Average time
- Upper and lower limit
- Drawing options
- Resolution

1. Display type

Your acquired signal may not be only a static signal; if you have ever tried to display a high-dynamic signal with digital values, you know that you have to make
some kind of statistic to get representative values. Therefore all instruments offer different display types, which can be selected from Display type drop down list.

NOTE: All these display types represent only statistic values for the online display. The settings have no influence on other displays or the data storage.

2. Display value

The digital meter can display different values. Besides the current measurement value, timing information can also be displayed:

Channel - current measurement value, assigned to an acquisition channel

Time - current time of the acquisition system

Date - current date of the acquisition system

Day + time - number of the day within the current year and time of the acquisition system; this format is compatible with the timing information according to UTC

Elapsed time - time elapsed from the beginning of measurement

3. Average time

With the Average time drop-down list, you can define the update rate for the selected instrument. As a standard, the values for the display type will be calculated Fast (0.1 s) over a period of 0.1 seconds, which represents also the internal minimum calculation period.

The system will still run at the dynamic sample rate and Dewesoft X will acquire the data with full speed, calculate minimum, maximum, average and RMS for this time interval, however, every data point will NOT be displayed on instrument and stored, but only these calculated values.

When From reduced rate mode is selected, the system will reduce the data continuously according to the static/reduced rate selected in STATIC/REDUCED RATE drop down list in the channel setup.

4. Upper and lower limit

You can set high and/or low alarm limits for each instrument, which will cause the instrument number to change from green to red when it is either above the high limit, or below the low limit.

If you want to use limits for an instrument, select it by clicking on it once. Use the Use check boxes to activate/deactivate high or low limit detection. If enabled, you can enter the alarm level for each.

For example, if we want to have the signal change to red when it either falls below 10 or rises above 7000 rpm, we set this meter up accordingly.

Note that the number changes to red as a standard when it is outside of both limits, and remains green when it is within the limits. You can set Lower limit, Upper limit, or both limits for each meter.

If you want to change the limit colour simply click on the coloured field next to the high or low limit field and choose the desired color from the appearing color selector window.


NOTE: The upper and lower limit is only a visual effect; it is completely independent from the Alarm monitoring function.

5. Drawing options

In Drawing options we can edit two different things:

- Show caption

Check box is ticked:

Check-box is not ticked:


NOTE: As standard, the caption is displayed.

- Use standard fonts

Check box is ticked:

Check-box is not ticked:


6. Resolution

Sometimes it is useful to be able to add one or two digital of display resolution, or delete one or two, according to the type of data being displayed.

Select a meter by clicking once on it. If Auto is checked, click either + (increase) button or - (decrease) button to add or delete digits to the right of the decimal point of the meter‘s display.



If Manual Resolution is checked, instead of + and - button Leading and Trailing field is displayed to enter number of digit.

Below this also Exponent section appears.

When Manual Exponent is checked, two buttons appear: to define exponent E in step by +3 and to define exponent E in step by -3.

The ANALOG METER is designed to give a graphical indication of the current value of a signal within the defined display range.

When you select an Analog meter in the design or run mode, following settings will appear on left and right part of the screen:

- Display type
- Average time
- Upper and lower limit
- Minimum shown value
- Maximum shown value
- Analog meter type

1. Display type

Your acquired signal may not be only a static signal; if you have ever tried to display a high-dynamic signal with digital values, you know that you have to make
some kind of statistic to get representative values. Therefore all instruments offer different display types, which can be selected from Display type drop down list.

NOTE: All these display types represent only statistic values for the online display. The settings have no influence on other displays or the data storage.

2. Average time

With the Average time drop-down list, you can define the update rate for the selected instrument. As a standard, the values for the display type will be calculated Fast (0.1 s) over a period of 0.1 seconds, which represents also the internal minimum calculation period.

The system will still run at the dynamic sample rate and Dewesoft X will acquire the data with full speed, calculate minimum, maximum, average and RMS for this time interval, however, every data point will NOT be displayed on instrument and stored, but only these calculated values.

When From reduced rate mode is selected, the system will reduce the data continuously according to the static/reduced rate selected in STATIC/REDUCED RATE drop down list in the channel setup.

3. Upper and lower limit

You can set high and/or low alarm limits for each instrument, which will cause the instrument number to change from green to red when it is either above the high limit, or below the low limit.

If you want to use limits for an instrument, select it by clicking on it once. Use the Use check boxes to activate/deactivate high or low limit detection. If enabled, you can enter the alarm level for each.

For example, if we want to have the signal change to red when it either falls below 10 or rises above 7000 rpm, we set this meter up accordingly.

Note that the number changes to red as a standard when it is outside of both limits, and remains green when it is within the limits. You can set Lower limit, Upper limit, or both limits for each meter.

If you want to change the limit colour simply click on the coloured field next to the high or low limit field and choose the desired color from the appearing color selector window.


NOTE: The upper and lower limit is only a visual effect; it is completely independent from the Alarm monitoring function.


4. Minimum and maximum shown value

You can define a Minimum and a Maximum shown value for the bar graph; this feature is very important to get a better scaling for the display.

For example your temperature measurement range is 0 to 1000 °C, but you measure only between 0 and 40 °C.


Just enter both values and the bar graph scaling will change immediately.

NOTE: This way changing Time axis can't be done in Design mode -> available only in Run mode.

5. Analog meter type

The analog meter offers four different appearances and can be selected from Analog meter type list.


First three options contain the channel name, display type and unit beside the measurement values.

The fourth Analog meter has two forms:
1. Full circle instrument
2. Compass instrument


NOTE: If you want to use the Compass instrument make a tick in Compass check-box.

The HORIZONTAL/VERTICAL BAR GRAPH is designed to give a graphical indication of the current value of a signal within the defined display range.

When you select a Horizontal / Vertical bar graph in the design or run mode, the following distinct settings will appear on left and right part of the screen:

- Display type
- Meter type
- Average time
- Upper and lower limit
- Minimum and maximum shown value
- Drawing options

Some of the settings are the same as the ones that we already described in previous visual controls.

These are the new ones:

1. Meter type

The bar graph has four different basic appearances: as a 2D, 3D, Needle or LED bar graph and can be selected from Meter Type drop down list. They all contain the channel name, display type and unit besides the measurement values.

All bar graph basic appearances can be in horizontal format- Horizontal bar or in vertical format - Vertical bar.


The orientation depends on the instrument type selected by the instrument icon in Design tool bar. Changing the orientation is not possible; you have to select the right instrument when you click on the icon.

The XY recorder is designed to display channels versus channels; there is no direct time relation.

The only difference to time-based displays is that the first selected channel is always used as the X-axis channel.

The X-Y recorder element can display up to three Y-axis channels, related to one other channel on the X-axis at the same time.

The cross on the XY recorder indicates the latest displayed value.


Graph type

The Graph type knows four modes:

  • Single x-axis - Allows only one channel x-axis. The first assigned channel is used for the x-axis, up to 4 following channels the y-axis.
  • Pairs of x-y - allows defining multiple "sets" of XY channels. First select the channel for the x-axis, then select a channel for the y-axis. This function allows you referring different channel to the different x-axis. NOTE: You still have only one x and y scaling. For example: x = distance 1, y = pressure 1. Now do the same for the second set, x = distance 2, y = distance 2.
  • Angle based XY - The first x-axis channel is the reference channel of the angle. It should go from 0 to 360°. The second (and further channels) are angle related data (like rotational vibration - XY recorder now displays the rotational angle of current revolution). This XY recorder is like a scope, but with angle reference instead of time reference.
  • Polar graph

Display type

Dewesoft X X-Y graph is now able to display the Real data. You can display also Average (for slow signals) or RMS values (for dynamic signals). As a standard, the values for the display type will be calculated over a period of 0.1 seconds.

Be aware that all Average and RMS display types represent only statistic values for the online display. The settings have no influence on the other displays or the data storage.

The angle based type for Angle based XY recorder can be selected between 360° and 720°.

You can display signals over a 1 period or 2, 3 or 4 periods which can be selected from drop-down list.

X and Y scale division

The X-Y recorder offers X scale divisions. You can select the number of X scale divisions from one to ten (= a dashed white line which divide graph area), which can differ between X and Y axis.

The X-Y recorder offers Y scale divisions. You can select the number of Y scale divisions from one to ten (= a dashed white line which divided graph area), which can differ between X and Y axis.

The Single value axis checkbox can be used to set all active channels of an X-Y recorder grid to only one Y-axis. If set, all channels will use the same scaling and as a visual result, there will be only one axis with values left. This function is very helpful when there is only small space for channel names and scaling and the channels use the same scaling.

Buffer

An option Load all buffer can be accessible only in Analysis mode. It shows all the cycles in the datafile, not only the selected region.

History

When the signal is changing very strong, it may be helpful to click the Show only current value checkbox in History section; this removes all displayed values from the X-Y graph and shows only the current value. Show only current value checkbox in History section; this removes all displayed values from the X-Y graph and shows only the current value.

Unselect this feature to receive the whole signal history again.

Draw filter

Especially for run-up tests, you should use the Only when x increases checkbox in Draw filter section. This is only a drawing filter and avoids any values displayed which become smaller than before.

Drawing options

With enabling the Draw sample points option, we display also the sample point together with the lines, connecting them.

Draw only sample points does not display any lines between the sample points.

X and Y directions can be in linear or logarithmic scale.

For Pen up option, we need another channel, that will change its value between 0 and 1. When the value is 0, the XY recorder is writing and displaying data and when the value is 1, the recorder is not displaying data.

With  Pretime limit we define the number of displayed samples.

Cursor type

The Delta cursor shows the changes in X direction (dX) and Y direction (dY) between the selected point on the graph (P1, P2). From the changes in both directions, also the angle of the straight line between the points in calculated.

The INDICATOR LAMP is designed to show the state of digital signals, to supervise the value of Analog signals in a true/false way, but also to show Discrete values.

The Indicator lamp is quite a simple element and displays next to the channel name only a coloured lamp, depending on the settings.

For example, when the Temperature drops below 40°C, the lamp becomes green. As soon as the Temperature grows above 40°C, the lamp becomes red.

The Indicator lamp visual control has two basic Display modes:

a) Indicator lamp: Shows the state of digital signals and to supervise the value of the analog signal in a true/false way.
b) Discrete display: Each channel can have a set of predefined values - for example, a binary CAN channel for ABS can have three states with codes 0, 1 and 2 which represents ON, OFF, and ERROR.

If we are in INDICATOR LAMP display mode:

- Display value
- Display type
- Average time
- Upper and lower limit

If we are in DISCRETE display mode:

- Display type
- Average time
- Options
- Discrete values

1. Display value

Possible Indicator lamp settings depend on selection in this field. For Indicator lamp, you can select among three basic Display values: Channel, Alarms and Storing.

Channel: Channel shows the state of digital signals helps you supervise the value of analog signal current measurement value, assigned to an acquisition channel in a true/false way

Three colours can be chosen - below a first limit, in between limits and above second limit.

For Channel option you be able to set:

- Display type
- Average time
- Upper / Lower limit

2. Display type

Your acquired signal may not be only a static signal; if you have ever tried to display a high-dynamic signal with digital values, you know that you have to make some kind of statistic to get representative values. Therefore all instruments offer different display types, which can be selected from Display type drop down list (last three choices only for Digital meter).

3. Average time

With the Average time drop-down list, you can define the update rate for the selected instrument. As a standard, the values for the display type will be calculated Fast (0.1 s) over a period of 0.1 seconds, which represents also the internal minimum calculation period.

The system will still run at the dynamic sample rate and Dewesoft X will acquire the data with full speed, calculate minimum, maximum, average and RMS for this time interval, however, every datapoint will NOT be displayed on instrument and stored, but only these calculated values.

When "From reduced rate" mode is selected, the system will reduce the data continuously according to the static/ reduced rate selected in STATIC/REDUCED RATE drop down list in the channel setup .

4. Upper & Lower limit

You can set high and/or low alarm limits for each instrument, which will cause the instrument number to change from green to red when it is either above the high limit, or below the low limit.


If you want to use limits for an instrument, select it by clicking on it once. Use the Use check boxes to activate/deactivate high or low limit detection. If enabled, you can enter the alarm level for each.

For example, if we want to have the signal change to red when it either falls below 10 or rises above 7000 rpm, we set this meter up accordingly (see picture above).

Note that the number changes to red as a standard when it is outside of both limit, and remains green when it is within the limit(s). You can set Lower limit, Upper limit, or both limits for each meter.

If you want to change the limit colour simply click on the coloured field next to the high or low limit field and choose the desired colour from the appearing colour selector window.


NOTE: The upper and lower limit is only a visual effect; it is completely independent from the Alarm monitoring function.

Alarm will show the state of alarm signals

For Alarm option you are able to set:

- Alarm from list; alarms are defined in Channel setup Alarms tab which is visible if alarm option is selected in channels setup
- Display type
- Average time

Storing shows the state of storing data. If data is stored, the lamp will go red, otherwise it will stay green.


Together with other different data of measurement in various instruments Dewesoft X provides Overload indicator display to show list information about overloaded signals.

The Overload indicator displays in tabular form channels information about:

- Index
- Name
- Description
- Unit
- Sample rate
- Values
- Overload


In Values column also channel min and max values is displayed, bar graphically shows the current levels of the signal with their limits.

In Overload column overloaded signals are designated graphically.

This is how the settings look like:

1. Display type

The Overload indicator display can show channel information for:
- All channels
- Selected channels

Select the Display type from drop down list according to your requirements.

When we select All channels option then the Overload indicator information for all channels gets displayed.

When we select Selected channels then empty Overload indicator appears:


In Channels selector, list of all available channels appears. From this list we can choose channels to display it in Overload indicator table.

2. Column selection

Dewesoft X allows us to select columns which are displayed on Overload indicator list.

Simply tick the box in Column selection in front of desired column name to show this column on Overload indicator.

1. RECORDER


The Recorder instrument is designed to show the time-history like the traditional strip chart recorder, but with enhanced display and analysis capabilities.

- Single/Multiple Time axis
-Display type
-Time axis type
-Y axis ticks
-Time and value cursor

When you select Recorder instrument in the design or run mode, following distinct settings will appear on left and right part of the screen:

Appearance on the screen:

The Recorder element offers all the important information like channel names, units, time information and zoom functions.

Because the Recorder is typically used to show longer periods of time - minutes or even hours or days - it has the added ability to show data in one of several fashions: Real Data, RMS, or Average.


Select any graph by clicking on it, and then select the Display type from the selector. This is useful when monitoring AC signals, which are going to look like a solid band when a long duration is show and is helpful (unless you‘re just looking for overall amplitude envelopes or obvious drop-outs). Changing the display type for this graph to RMS will show a more useful representation of the data.

For noisy DC signals, selecting Average can clean up the display.

IMPORTANT: Be aware, that all these display types represent only statistic values for the online display. Settings have no influence on the other displays or the data storage.

Just have a look to the following screen to see the difference between the three display types.


Use the Show events checkbox to enable or disable the view of event markers. You can also see all your events - keyboard, notice, and voice types - on the event list at the top right, directly below the replay control buttons.


2. VERTICAL RECORDER

The Vertical recorder instrument is designed to emulate the time-history plotting capabilities of the traditional strip chart or recorder, but with vertical Time axis orientation and enhanced display. On each vertical recorder only one channel can be displayed.


Appearance on the screen:

The Vertical recorder element offers all important information:
- channel number (group, description and slot)
- channel name(s)
- unit(s)
- time information
- zoom functions...

Appearance is like for Recorder, except Time axis is vertical.

If you want to change the X-axis for any input, the recorder offers two possibilities:

- Enter values

You may enter the values by yourself - simply click on the number at both extreme and then type in a new number.

- Auto scale

Move cursor to the axis scale. Press left mouse button to activate auto scale for this channel or press right mouse button to undo auto scale. The auto scale function always calculates the minimum and maximum value of the currently displayed signal and use these values for scaling. The scaling will be only updated when you press the left mouse button.

Additional Auto scale functions

Dewesoft X offers additional auto scale functions when you press keys together with the left or right mouse button:

Left mouse button - Auto scales the selected channel (see also above).

<SHIFT> + Left mouse button - Scales the selected channel symmetrical around zero (± values are the same).

Right mouse button - Undo auto scale for the selected channel (see also above).

Display type

Display types of Vertical recorder are same as by Recorder, except Time axis type is vertical.

X scale divisions

The Vertical recorder offers X scale divisions. You can select the number of X scale divisions from one to ten (=dashed white line which divide graph area) from drop down list.


Alarm levels

You can set high and/or low alarm limits for each Vertical recorder, which will cause the recorder to mention the alarm above the grid. As a standard, the alarm values are set to the minimum and maximum range for the appropriate channel. If you want to use own limits, just enter the alarm level according to your requirements.


Now we have set the limits to +1 and -1 mm, indicated by the two small white lines directly above the scale. The two yellow lines show the minimum and maximum value during this acquisition, which may be even outside the displayed time window. Finally, a line in the colour of the channel indicates the current value; a small line indicates just small changes in the signal for the last 0.1 sec, the wider the line the higher the change in the signal.

Example 1

The current signal is within the defined limits of ±1 mm, indicated by the two white markers.



Example 2

The signal is out of the defined limit, the current value is displayed in red letters as long as the signal is out of the limits.


Example 3

The signal is back within the limits, the previous exceed of the limit is indicated by the three red !!!. You can also still see the maximum level indicator out of the limits.

The Scope instrument is used for displaying fast, short-time events. Like in a traditional scope you can define trigger conditions. Up to 16 inputs can be displayed at once in each graph.

The Scope element in the overview offers all important information:
- channel name(s)
- unit(s)
- time information
- zoom functions...

When the scope is not triggering, the bar on the right side shows the current levels of the signal so we can optimize the trigger level according the normal values (we can also use Auto trigger mode). When the trigger is lost for some seconds, data will be shown none triggered.


Run mode Zoom (additional appearance setting)


At the top right above each graph in Norm or Single Trigger mode you maybe have already noticed a small icon. Pressing it enables / disables the zoom view during acquisition. Up to now, when you press the blue + and - buttons at the bottom right side of each graph, you also changed the memory depth used for the acquisition.


If we want to see the event now more detailed, just click the zoom icon. At the top of the graph you will now see a scroll bar indicating the current displaying position within the whole acquired signal. Press the + button to zoom in (or - to zoom out).

When you move the mouse over the scroll bar at the top, it will change its appearance to a "hand". When you press the left mouse button and move the mouse, you can change the current position and scroll through the whole acquired data of the current trigger shot.

The Scope instrument typical settings include three main groups:

- Trigger (Free run, Auto, Norm, Single)
- Cursor (cursor measurement to show the cursor readouts for each channel within the selected scope; with Reference curves possibility)
- Scale (to change displayed offset and scaling of signals)
- History (to display the trigger events in different ways history type, to select how many trigger events will be used, to browse through the trigger events, to export the acquired data)

1. Trigger settings

Dewesoft X knows four types of Trigger operations:

FREE RUN (All values are displayed, no trigger active and there are no additional settings)

AUTO (The auto trigger displays values if the trigger condition is true; when there is no trigger within some time, it displays the current value)

For this type of Trigger operation we can set:


  • Timing setup
  • Current trigger setup with:

- select the desired channel
- define the Value
- define the Mode - trigger type
- setup trigger condition for selected trigger type:

  • Mode

- simple edge
- filtered edge
- window
- pulse width
- window and pulse width
- scope

  • Store trigger settings

- NORM (The normal trigger displays only values if the trigger condition is true)


For this type of Trigger operation can be set the same setting as for Auto trigger.

When the Norm (orSingle) trigger is selected, another tab appears - History.

- SINGLE (This function can be used to acquire single events)

After selecting single button, this button changes to Rearm.


Press it to get another single shot event.

For this type of Trigger operation can be set the same setting as for Auto trigger. When the Single (or Norm) trigger is selected, another tab appears - History.

2. The timing setup

The Timing setup can be used to define the displayed Pre and Post trigger time in milliseconds.

HINT: Like the trigger level, the trigger position can be changed within the displayed time window by moving the white vertical line in the scope graph. Simply click on the line, keep mouse button pressed and move the line to the desired position.

The time window can also be changed using the blue + and - buttons at the right bottom of each graph.

3. Current trigger setup

The trigger conditions for Auto, Norm and Single data trigger are the same and work in the same way than described in Using trigger to start and stop recording.

1. select the desired channel
First of all you have to select the desired channel out of the drop down list. It displays all available channels.

2. define the Value
Select the Real data, Average or RMS from the drop down list.

3. define the Mode
Select the trigger type Simple edge, Filtered edge, Window, Pulse-Width, Window and pulse-width or Slope from the drop down list.

4. Setup other
These settings (e.g. Slope, Trigger level, Rearm level, Pulse time,...) depend on selected trigger type in Mode field.


HINT: The trigger level can also be changed by moving the white vertical line in the scope graph. Simply click on the line, keep mouse button pressed and move the line to the desired position.

3. Store trigger settings

This is a very nice function to define the storing options directly within the scope.

Any changes done here are automatically copied to the system trigger and vice versa. To activate this function press the Link store trigger button.

The drop down list next to the button shows - if already available - existing triggers conditions or starts with a fresh entry T0.


The + button can be used to define additional conditions, which can be selected by the drop down list and changed according to your requirements.

The - button can be used to delete selected additional conditions.

WARNING: As long as the Link storage trigger button is not pressed, the data is only displayed - not stored!

The Dewesoft FFT (Fast Fourier transformation) instrument shows the frequency components of acquired signals in amplitude and frequency.

The FFT element offers all important information:
- channel name(s) unit(s)
- frequency information zoom functions...

1. FFT Setup settings

- Line resolution

The FFT lines are responsible for the frequency resolution. The higher the FFT lines value, the better the resolution - but also the higher the calculation time.

This line resolution depends on the sampling rate and the number of lines chosen for the FFT. So if we want to have a fast response on the FFT, we choose less line, but we will have lower frequency resolution. If we want to see exact frequency, we set higher line resolution. Simple rule is: if it takes 1 second to acquire the data from which the FFT is calculated, the resulting FFT will have 1 Hz line resolution. If we acquire data for 2 seconds, line resolution will be 0.5 Hz.

The current frequency resolution is mentioned in the selection line next to the heading (df = n Hz).

Example: The sampling rate has been set to 10000 Samples / sec and the resolution to 1024 FFT lines. These settings allow an FFT analysis up to 5000 Hz (half sampling rate). Now you divide the max analyses frequency by the FFT lines (5000 Hz / 1024 lines). The result is 4.88 Hz per line resolution (mentioned in the selection line).

To change the FFT lines, just click in the Line resolution field and select from the drop down list.

- Window type

Dewesoft X supports the most common Window types for FFT analysis. Select the window from drop down list according to your application.


- X and Y Scale type

Dewesoft X allows:
- two different X (frequencies) axis types (Linear and Logarithmic)
- four Y (amplitudes) axis scaling types (Linear, Logarithmic, 0 dB and Noise dB and Ref. dB scaled)

Select the axis type from drop down list according to your application.

When in Y scale type Ref. dB is selected, 'Db scaling reference point' window appear to enter this reference point and confirming that with OK.

- Number of ticks

You can select the Number of ticks from one to six ticks (dashed white line which divide graph area) for your FFT display, which can differ between X and Y axis. The first field in row is to select the X axis ticks, the second row for the Y axis ticks.

- Amplitude display

The Amplitude display section defines display in Y-amplitude axis.

From Amplitude display drop down list we can select different types of amplitude scaling of the FFT. Basic setting is Amplitude (Auto), which shows for pure sine wave the amplitude of the sine.


Amplitude typeUnitsDescription
Amplitude (Auto)
V
is the pure signal amplitude
RMS
V rms
is the RMS amplitude, calculated as Amp litude/sqrt(2)
Power
V * V
calculated as RMS value squared
PSD
V * V / Hz
calculated as RMS squared, divided by the line resolution and sqrt(2)
RMS SD
V / sqrt(Hz)
calculated as RMS value, divided by the square root of line resolution - also used for checking the noise

- DC cutoff

To remove DC or low frequency components, select from drop down list the DC cutoff filter - lower limit.

- Weighting

As a standard, FFT analyses use a Linear Weighting. For sound analysis, special FFT weighting can be set. As opposed to the sound module in math, where the weightings will be calculated in time domain, this will calculate the sound weighting in frequency domain.

The FFT visual control can display the position and amplitude of maximum peaks, RMS values or marked peaks.


2. FFT History settings


- Current FFT

Display current FFT with settings in Setup tab (see above). Just select Current FFT from Display mode drop down list. Only this one setting is necessary for this Display mode type.

- Averaged FFT

Use averaging mode to get a more stable FFT display. To activate the averaging just select Averaged FFT from Display mode drop down list.


Average type

From Averaging options select Average type: Linear, Exponential or Peak. As a standard, linear is selected.

Overlap

Depending on the application, it may be necessary to define a data overlap. When the window type is used, we have to use overlap otherwise some of the data will be ignored. Therefore the use of overlap is highly recommended.


The Dewesoft X orbit plot shows the x-y scope with a chance to rotate x and y axis. It is mainly used for displaying the axis movement in DSA analysis.

Integration/double integration can easily be done directly in the channel configuration setup, for calculation of displacement based on accelerometer input. The output of the Order tracking module can be used for displaying single orders as well as cyclic averages.

1. Mounting angle

Angle is defined for first and second channel and depends on the mounting of the sensors.

For example: if the first channel angle is mounted from the top, we select 90 degrees. If it is from the right side, we select 180 degrees.

NOTE: the sensors should not be mounted in a straight line - there should be an angle offset between them.

2. Graph type


Since order tracking defines the rotation frequency, we can display current rotation - One rev. mode, Averaged number of cycles or More revs (cycles). For last two modes we need to define the number of cycles to average or display. Please note that Order tracking needs to output also Phase angles. In other case the Orbit analysis will display a warning.

3. Drawing options

The last option to set in both modes is Remove DC, which, if it is checked, will remove the offset from the signal and will display the orbit in the center of the graph.

If this option is not checked Harmonics list is dimmed and values are not available.

Next we are going to describe visual control that is used for visualisation of the Sound Pressure Level: Octave analysis (display).

The quickest way is to do the visualisation only with the instrument called “Octave plot”. You only need to set the y-axis to “Sound dB” to display the result.

Further options are: 1/1, 1/3 up to 1/24 octave resolution; weighting (A, B, C, D, Lin); Averaging (Lin, Exp, Peak) with overlap (0 to 75%).

1. CPB options 

We can choose between different Analysis types.

For 1/3 spectrum, there will be 10 bands per decade, for 1/12 there will be 40 and for 1/24, there are 80 values.


This is the difference between different types:

Example of a 1/1-octave filter:

Example of a 1/3-octave filter:

Example of a 1/12-octave filter:


Y scale type can be chosen between

Dewesoft X supports two display types which can be selected from drop Band display type down list according to your application:

There can be different Weighting:

  • A-weighting: A-weighting is applied to measured sound levels in effort to account for the relative loudness perceived by the human ear. The human ear is less sensitive to low and high audio frequencies.
  • B-weighting: B-weighting is similar to A, except for the fact that low-frequency attenuation is a less extreme (-10 dB at 60 Hz). This is the best weighting to use for musical listening purposes.
  • C-weighting: C-weighting is similar to A and B as far as the high frequencies are concerned. In the low-frequency range, it hardly provides attenuation. This weighting is used for high-level noise.
  • D-weighting: D-weighting was specifically designed for use when measuring high-level aircraft noise in accordance with the IEC 537 measurement standard. The large peak in the D-weighting curve reflects the fact that humans hear random noise differently from pure tones, an effect that is particularly pronounced around 6 kHz.
  • Z-weighting (linear): Z-weighting is linear at all frequencies and it has the same effect on all measured values.


2. Averaging

When Averaging is enabled, you can choose between Lin, Exp or Peak. Averaging mode is used to get more stable Octave display.

To activate the averaging just click the Enable checkbox on Averaging section and all controls become available.

Averaging means that we calculate many FFTs during the time and are averaging the frequency lines.

  • linear averaging (each FFT counts the same in the results),
  • exponential (FFTs becomes less and less important with time),
  • peak hold (only maximum results are stored and shown).

Depending on the application, it may be necessary to define a data overlap. When the window type is used, we have to use an overlap otherwise some of the data will be ignored. Therefore, the use of overlap is highly recommended. Overlap defines how much of the old data will be taken into account.

It takes some part of the time signal, which is already calculated and uses it again for calculation. There could be any number for overlap, but usually there is 25%, 50%, 66.7%, and 75% overlapping.

50% overlapping means that the calculation will take half of the old data.

1. VECTOR SCOPE


The Dewesoft X Vector scope instrument is used for displaying the amplitudes and phase angle between the voltage and current power module channels and additional to the vector also the most important measurement values for each phase: Ui, Ii, Phi, cos Phi, Pi, Qi and Si.


NOTE: Vector scope instrument on Design tool bar is available only in case of selection at least one power module in Dewesoft X Setup - Power tab.

1. Apperance on screen

The Vector scope displays the phase angle between the channels and:
- channel names
- unit(s)
- frequency information typical values

2. Measured values

his function shows in addition to the vectors also the most important measurement values for each phase: Ui, Ii, Phi, cos Phi, Pi, Qi and Si (where i is the number of the selected harmonic).

Use the Show measured values checkbox:


3. Harmonic selection

The Harmonic shown selection allows changing the displayed harmonic. You can choose from 1st to 50th harmonic.

Use the Up / Down arrow to increase /decrease the displayed harmonic.

4. Axis settings

- Automatic
With Automatic enabled, the vector scope always scales to the maximum of all displayed channels.

- Manual set
When Automatic is disabled, you can enter value for: Umax and Imax Use the Up / Down arrow to increase /decrease number of ticks -Tick count


2. HARMONIC FFT


The Dewesoft X Harmonics display shows frequency components of the input signals. Harmonics analysis is similar to the FFT analysis, the main difference is the type of calculation and displaying: the harmonics display refers to a base frequency (e.g. 50 or 60 Hz) and displays its harmonics.

NOTE: Harmonics instrument on Design tool bar is available only in case of selection at least one power module in Dewesoft X Setup - Power tab.

1. Appearance on the screen

The Harmonics displays shows: base and harmonic frequencies, channel name(s), unit(s)...


2. Display value

Dewesoft X Harmonics display always shows all channels from one module at the same time. The Display value defines what the content should be from the channel selector on the right side:
- Voltage
- Current
- Power - active power
- Reactive power - this is wasted energy
- Line voltage

3. Draw full FFT 

With check Draw full FFT checkbox in Display value section instead harmonics bars full FFT spectrum can be displayed.

4. Data panel

Show data panel

This function shows in addition to the bars also the most important measurement values for each phase: Ui, Ii, Phi, cos Phi, Pi, Qi and Si (where i is the number of the selected harmonic).

To display this values check the Show data panel checkbox (example picture see above) in Data panel section.
To select a Harmonics, which values will be displayed in data panel, simply move the mouse cursor over the bars, a grey harmonics cursor (rectangle) will follow and indicates your selection.

When you want to fix your selection press the left mouse button (on example above 1st harmonic is selected). To select another harmonic move the mouse to its position and left-click again.

If you want to release the harmonics cursor move the mouse to its position and left-click again. Now the harmonics cursor is 'free' again.

NOTE: Harmonics cursor works only by checked Show data panel checkbox.

5. Y axis display

In this part of Harmonics display settings you can choose with check / uncheck appropriate box different Y axis scaling:

- Logarithmic

Logarithmic checkbox in Y axis section is:

  • Selected logarithmic Y axis scaling (example see right)
  • Unselected linear Y axis scaling (example picture see above)

- Show percentage

Show percentage checkbox in Y axis section is:

  • Selected (the Y axis is scaled in %)
  • Unselected (the Y axis is scaled in it's units (V, A, W or Var))

1. CA p-v DIAGRAM


The Dewesoft X Combustion analysis p-v plot shows the x-y scope volume vs. pressure in the cylinder. The combustion math module should be used that this graph can be chosen.

1. Scale type

The scale can be displayed either as linear or logarithmic (for volume and pressure). Linear axis is common used type for seeing the real value of the pressure, while logarithmic have two advantages: the pumping cycle can be seen very nicely and also the polytropic expansion and compression are linear in log-log scale.

2. Drawing options

We have also an option to draw start of combustion and end of combustion points (SOC, EOC). This shows the points where start of combustion and end of combustion happens (calculated from the heat release).

Additional option with logarithmic scale is to display the Polytropic exponent. This is used to see howgood the entered polytropic coefficient fits to the measurement data.

3. Online calculation

To keep an overview over the p-v, Dewesoft X can calculate the Max pressure, SOC (start of combustion points) and EOC (end of combustion points) values.

To activate the calculation,just click on Values button and Values table appear:

2. COMBUSTION SCOPE


The CA-Scope can be used for all angle based data from the CA-mathematics. The results can be shown from actual data, from running or overall average and as well from the additional channels. The illustration below shows the Cylinder pressure (on the left) and the heat release data (on the right).


 

Dewesoft X 2D graph shows the drawing of any matrix channels. Some typical examples are FFT created from math channels, classification and others.

When you select 2D graph, following distinct settings will appear on left and right part of the screen:

  • Control properties (adding visual controls, transparency, number of columns)
  • Display options (Auto scale, graph type, ....)
  • Interaction (markers and marker table)
  • Channel selector (for assigning and reassigning the channel on graph)

The input to the 2D graph can be:

- FFT math
- STFT math
- CPB math
- classification
- counting
- scope trigger
- FRF math
- SRS math
- CA pressure and other channels

In short, a 2D graph can show any array channel created by Dewesoft X.

Display options

There are several properties which can be set to 2D graph.

Auto scale

  • Off - the channel will not be scaled automatically, we enter the min and max of the range
  • Per channel - each channel will be scaled according to its range
  • All channels - all channels will be scaled to the same range (to the range of a channel with the biggest amplitude)

Graph type

Automatic will set the graph type to what is set in the input channel. For example, FFT has the default graph type of lines while CPB has the histogram. We can override these settings by manually defining either Line or Histogram.

  • Line 
  • Histogram 

Histogram type for histogram type, we can define to either fill the bars with Full option, or to draw empty bars with Empty option or to simply draw the Line at the top for a very classical instrument look.

  • Full option
  • Empty
  • Line

X-axis type can be either linear or logarithmic.

Y-axis can be:

  • linear
  • logarithmic
  • 0 dB - Scale in dB gives the best estimation of signal noise - if 0 dB is maximum measurable value
  • Sound dB - the equation for calculating dB is: 20*log10(p/p0) where the p is our value and p0 is the reference of 20 uPa
  • Ref. dB - with the Ref. dB we define our own reference value

Number of ticks defines either automatic or manual number of graph divisions for x and y-axis. Division for y-axis can be freely defined only for linear scaling, log scaling defines the number of ticks from minimum and maximum axis value.

Single value axis option will set one y-scale for all channels in the graph.

With the Hide axis name option, we hide the name of the assigned channel - only the y-axis scale is shown.

Persistence will slowly fade the old data on the graph. We can define the number of old arrays to be shown. The larger the number, more history will be seen.

Interaction

The 2D graph can display values of the currently selected point with the markers. When clicking on such point with the left mouse button, the marker line will be added showing x-axis value on the x-axis and showing y-axis value of certain point above the marked point. All points can be removed by pressing the right mouse button.

The type of markers:

  • selection
  • zoom
  • free marker
  • max marker
  • harmonic marker
  • sideband marker
  • RMS marker
  • damping marker
  • cursor channel
  • bearing marker

You can find out a lot more about markers, how to add and use them is the Spectral analysis with the FFT course.

Marker table shows the ID, color and the coordinates of the markers (X and Y-axis value). We can make markers visible or not and edit them (change the position of each marker).

The Show marker option shows the amplitude and the frequency of different markers, put on a 2D graph.

Campbell plot or diagram enables us the visualisation of 3 dimensional values on a single plane. It is mostly used in Order tracking.

Range of values is segmented in defined number of levels and each level is represented by a circle, whose radius and colour depend on level's index; bigger values are represented with larger circles and colors higher on the color map. For better analysis of data, cutoff of lower levels can be applied.

This instrument works based on classification of the measured values, with several options for diagram design and adjustable properties of classes. It can be applied on FFT waterfall vs. RPM as well as on Order waterfall vs. RPM from Order tracking module.

Click on Design button and add Campbell plot with clicking on the icon shown below.

On the upper graph an ordinary 3D graph in shown and the lower one is Campbell plot.

Also, the order FFT can be displayed.

Campbell plot presents multiple options to manipulate its design.

Minimal and maximal value on the diagram’s scale (on the left side of Campbell plot visual control) represents the range of values which will be segmented into levels. Values, bigger than maximal value, belong to the highest level and values, smaller than minimal values fall into the lowest level. On the picture below we can see an example, how value’s range is segmented into levels, where number of levels is set to 5. Number of levels can be changed within Levels edit field on the Options tab.


Cutoff is given in percent. It determines size of portion that will be cut out from the range of shown values. Diagram’s scale shows which values will not be shown by hiding scale’s colour map. Next picture shows example with no cutoff (0%) on left side and on the right side cutoff was equal to 30%. Scale’s colour maps are changed accordingly.

NOTE: By clicking on the diagram and hover over the scale with your mouse, you can easily define your Cutoff with scrolling up and down.

High and low value sizes correspond to the diameters of circles from highest and lowest level, respectively. Diameters of circles from levels in between increase linearly from lowest to highest diameter with respect to number of levels. Each level has its own diameter.

Scale’s colour map can be generated from different palettes (Palette dropdown). Below you can se examples of all of them; Rainbow (warm), Rainbow, Gray scale and single colour, which is colour from the channel on the diagram.


There are two possible circle styles; outline (by default) and fill. On the left filled circle style is shown and only outlined circle on the right. 

Campbell plot lets you choose between XY and YX projections. XY has x axis horizontal and y axis vertical, YX projection has it the other way around; x vertical and y horizontal.

Positions of x and y axes are set as on the selected icon. Left we have XY projection and YX on the right. 


Selection marker (selected on the image below), shows you the value of the area where your mouse cursor is currently positioned on the diagram. Value is shown in upper left corner of visual control.



Free marker (not selected above), allows you that you can mark the position with one left click on the mouse on the wanted area. You cannot click on the area where there are no values (cut out levels). Little cross will be drawn, to show marker’s position with its index written on the side. If Show marker values is checked, value on the marker will be shown instead of its index. On the picture there is also marker table, which has all markers values collected. Only for demonstration reasons on the picture below, line connects markers and their values in the table. 

The Dewesoft X 3D graph shows three-dimensional arrays or arrays with history. With this graph, we can show FFT history, order tracking, drain flow count, and even Thermo vision data.

When you select 3D graph, following distinct settings will appear on left and right part of the screen:

- Display options
-Tick marks
-Z Axis
-Projection
-Cursor Type


1. History count

History count defines the number of lines which will be shown on the display. Number of lines depends on the amount of memory reserved by the channel. Please note that increasing the value might result in very slow display since it requires lots of computing performance.

With the “history count,” you can increase the shown buffer.

2. Tick marks

3. Z axis

Z axis type can be set to either logarithmic or linear. Minimum and maximum of each scale can be defined by clicking on the min and max value like in any graph. That also works for the z scale which is on the left side of the display.

Z axis palette can be either in rainbow or grayscale color.

Auto scale will automatically scale z axis.

4. Projection

The Projection of the axis can be changed. First icon (x up, y right) is planar view and is mostly used when time based data is shown like FFT history, for example. The second one (x left, y up) is useful when displaying matrix channels like rainflow count or thermovision picture. Order tracking is in between, some users prefer first while another persons prefers second way. There are also two three dimensional views.

In Projection we can choose between 2D graph or 3D graph.

5. Cursor type

Moving the mouse button around on the graph will place the cross hair cursor on the nearest point on the graph.
When clicking on the point for a short period of time (long click will rotate the display), the cross hair will be held in place and the value of all three axis will be displayed near the cursor. All the cursors can be removed with right mouse click.


The inputs to the 3D graph could be:

- block based FFT math
- STFT math
- block based CPB math
- order tracking order and frequency based history
- 3D rain flow counting
- FLIR thermal vision picture (requires special plugin).

NOTE: 3D view might not be available on computers which don't have DirectX installed or the graphics card doesn't support 3D features required from a graph.

Settings in 3D:

  • Auto scale will automatically scale z axis.
  • History count defines number of lines which will be shown on the display. The number of lines depends on the amount of memory reserved by the channel. Please note that increasing the value might result in very slow display since it requires lots of computing performance.
  • The Z axis type can be set to either logarithmic or linear. Minimum and maximum of each scale can be defined by clicking on the min and max value like in any graph. That also works for the z scale which is on the left side of the display.
  • Z axis palette can be either in rainbow or grayscale color.
  • The Projection of the axis can be changed. The first icon ( x up, y right ) is planar view and is mostly used when time-based data is shown like FFT history, for example. The second one ( x left, y up) is useful when displaying matrix channels like rain flow count or Thermo vision picture. Order tracking is in between, some users prefer first while another person prefer second way. There are also two three-dimensional views.

The three-dimensional view can be rotated by pressing and holding the left mouse button to rotate it. Scrolling the mouse wheel or pressing Shift and left button will zoom in or out the display when moving the mouse up and down. Right, click and moving the mouse will rotate the graph around the display plane.

Cursor operations

Moving the mouse button around on the graph will place the crosshair cursor on the nearest point on the graph. When clicking on the point for a short period of time (long click will rotate the display), the cross hair will be held in place and the value of all three axis will be displayed near the cursor. All the cursors can be removed with right mouse click.

Additionally, we can change the cursor to calculate the slope between x and y axis. First we click on the first point, then on the second point and the value on the left will show (in our case) speed of frequency change over the time.

2D / 3D table is designed to display numeric values of signals on measured frequencies. It can be used for faster determination of amplitude at specific frequency.

Input

  • Math,
  • FFT Analyser math,
  • Order tracking math.

Design options

In addition to normal Group functions, you can also display multiple channels in one window with common frequency column.


2D table maximum frequency:

Maximum frequency displayed in the table is dependant on Bandwidth selected in Channel setup -> Analog in .


3D Table:

3D Table can be used along with 3D graph for numeric representation of graphically displayed data. In 3D mode, only one channel per table can be displayed.


3D Table row and column definition:

Row and column size and resolution is set in Order tracking setup by changing “Calculation criteria - frequency limits” and “Order FFT setup”.

Dewesoft X provides together with other different instruments also Tabular values display to show list of all the measured data and related time.

When you select Tabular values display in the design or run mode, following settings will appear on left part of the screen:


1. Display type

The Tabular values table displays in separate columns:
- Time data
- Values of channels


2. Display options

The Tabular values display offer three possibilities:

- Display time

When we select this field check box, time data from measurement start in predefined format is displayed, if it is not checked, the Time column is hidden. All values of selected channel are displayed.


- Absolute time
When we select this field check box, the date is displayed additional in absolute time format. All values of selected channel are displayed.


- Print on value change only
When we select this check box, additional part of Tabular values setting - Change threshold section is displayed (description see below). Only selected channel values which meet condition that is defined in Change threshold field are displayed.


3. Print format


The Tabular values display offer settings for displayed channels values:

- Scailing
Select the Scaled or Raw type from drop down list according to your requirements. Usually the scaled value is displayed, but sometimes it is nice to see the raw channel values, especially when data is transmitted digitally (CAN, PCM or other digital buses).

When Raw type is selected, then new field appears:

- Raw value format
Select the Hex, Decimal, Octal or Binary format type from drop down list according to your requirements. This is valid only when raw values will be displayed.


4. Font

Dewesoft X Video display provides showing content sensitive acquired videos together with other different data of measurement in various instruments. This video information can help to interpret and to document these data and measurement.

NOTE: Video display possibility on Design tool bar is available only in case of physical connection and set up of camera in Dewesoft X Setup - Video tab .

1. Apperance on screen

The Video display present content sensitive acquired video information.

2. Camera (Video) settings

  • Unproportional

3. Cameras selector

It will display the available cameras to select the right one.

Dewesoft X provides new control elements, allowing users to control Dewesoft actions like start and stop or to directly influence outputs, like function generator parameters.

Control element have two basic mode of operations:
- Dewesoft action to control Dewesoft X for example in full screen
- Control channel operation to manually control function generator or for example some of digital outputs

In the Dewesoft action mode, only push buttons are allowed. There are several actions possible:
- Start .... will start the measurement from Stop mode
- Stop ... will stop the measurement (and storing)
- Pause ... will pause recording, it is actually pause/resume toggle - if paused, it will resume measurement
- Freeze ... will freeze the recorders if Freeze buffer is enabled in Project setup
- Store ... will start storing
- Trigger ... will issue manual trigger in Store mode
- Screen select ... will select the screen named the same as Action string

Action string defines the name of the button.

When using Control channels, we can display Control element as:
- Input field ... to manually enter a new control value
- Push button ... to allow short on/off event
- Switch ... to switch between two or more states (could be defined by the control channel)
- Turn knob ... to allow smooth transition between values defined by min and max
- Horizontal / vertical slider ... same as turn knob, but linear

For turn knob, horizontal and vertical slider we can also define minimum and maximum limit. In analyse mode Control element has no function.

Dewesoft X offers an additional data displays and controls to create instrument appearance on the online display screen.

STATIC IMAGE

The static image can be used to illustrate your measurement or as base picture to place different instrument displays with measured data on it.


When you select the Static image control in the design mode, the empty place holder for the picture is placed on display. We can resize it and place the image onto the place holder by pressing the Load button in the control setting on the left side.


A standard OS dialog will open allow to load any jpg, jpeg, bmp, ico, emf and wmf image. Pressing Open will load the image.


We have an option to Scale the image proportionally to the size of the placeholder with Full option, we can scale it to proportionally or keep the original size.

NOTE /TEXT ELEMENT

The Text element can be used to write any text at any position of the screens like caption, comments and reminder.

When you select the Text notice in the design or run mode, on left part of the overview screen a text controls will appear:


NOTE: the Line element doesn't have any Channel selector.


The Text element is very simple: just a field where you can enter your text.

In the Font section, you can define the text styling in same way as by other Windows text editors. Choose from all installed fonts on your Windows system, define the font Size, Color and appearance like Bold, Italic or Underlined.

The Paragraph section contains two features: the Alignment of your text (Left, Centered or Right) and the Word wrap (active by default).

Press the Edit button on Text editor section or simply double-click on the text field to enter or change the text.

In Edit mode we can also enter some variables, like setup file name, data file name, data file length or global header entry.
For the global header, we need to write the name of the header entry, for example <GLOBAL_HEADER SECTION=Comment>


When you have finished, simply click anywhere outside of the text element or press once again Edit button to confirm the changes.

LINE ELEMENT

The line control can be used to draw lines, connect different elements, mark something,...

When you select the Line control in the design or run mode, on left part of the overview screen a line control will appear:

NOTE: this the Line element doesn't have any Channel selector.

1. Line element appearance

The Line element is very simple: just click once where you want to start your line and the second time where it should end.

2. Draw shapes

In Shape section you must first check Closed (and in case of need Filled) field, then:

1. you draw line with two points (first two corners of shape) as described above
2. move mouse cursor to third corner of shape, press and hold Shift key on keyboard and when you left click the shape appear; while pressed left mouse button, you can move this corner on desired location; with releasing left mouse button (and consecutive Shift key) shape is drawn
3. on this way you can add fourth, fifth,... corner

3. Positioning and size

- To modify a line, simply click once on it to select element and then move the end points to the desired new location. On same way you can modify shape change position whichever corner. When cursor is over start / end point of line or over corner of shape, change to 'hand' and modifying is possible.

- To move whole line or shape, simply click once on it to select it and then move (with cursor on line / shape and with pressed left mouse button) whole line or shape to the desired new location.

4. Line, arrows and shape properties

Use the Line, Arrows and Shape sections to style up your line with different colors, widths, arrows,... - please try out the functions to find the best for your requirements.

Balanced rotors are essential for most kinds of rotating machinery. Unbalance will create high vibrations causing material defects and reducing lifetime of a material. In most cases the rotor unbalance is the major problem of vibration, it is related to the first order (= rotational frequency).

The goal of balancing is to minimize vibrations related to the first order. Basically it works like this: We measure the initial state, then we add a trial weight of known mass, calculate the position and mass of a counterweight, remove the trial weight and put the calculated weight on the opposite side, to cancel out the imbalance.

This is how the visual control in Dewesoft X looks like:


There is a complete PRO training course written on Balancing, explaining all the settings and procedures. Check it now: http://www.dewesoft.com/pro/course/balancing-44

With FRF geometry editor, you can quickly draw simple structures, as well as import more complex ones. If you want to import the structures, select the Load UNV option.

The search window will appear and you have to define the path to the UNV file.

After that, the geometry (nodes, lines, ...) is ready to be used for animation.

When we want to draw our own structure from beginning, we have to enter the UNV editor.

In the UNV editor, we define the nodes, trace lines, triangles and quads. Each defined or imported point has its own index (for animation) and coordinates (in cartesian or cylindrical coordinate system).

Visit Dewesoft PRO training course Modal testing for more information's about UNV editor.

The geometry can be freely moved and zoomed in and out in the Mode section.

  • Rotate the geometry around all of its three axis. 
  • Translate the geometry over the available space. 
  • Scale the geometry and take a look at its details. 

With the Scale and Speed number, we define the amplitude and speed of the animation nodes.

In the FRF geometry visual control we can display either nodes, numbers, trace lines, quads or coordinate system.

The object that is selected (in a yellow rectangular) will be shown in the visual control, other objects will be hidden.

Example: the nodes, lines and quads are shown (in a yellow rectangular) while the indexes of nodes and a coordinate system are hidden.

The point of animation is selected in the Show frequency window. We can animate the structure from the cursor channel or we can manually insert the frequency.

Polygon is a platform for tests involving moving objects. It was made especially for vehicle dynamic testing and advanced driver assistance systems - ADAS, which increases safety in the traffic. Polygon provides a visual representation of measurements in the three-dimensional virtual space. It also provides easy tools for geometric measurements between multiple static or movable objects. Polygon visualization and outputs can be calculated during the measurements or after in offline mode. Due to it's flexibility it's not only used in Automotive, but also Marine, Heavy machinery, ...


In Polygon 3D visual control we can set up different things:

1. Camera position


  • Manual means that view angle can be adjusted to any position manually. It can be translated with right mouse button, rotated with left mouse button and zoomed in and out with mouse wheel or pressing both mouse buttons and moving the mouse up and down.
  • Attach to car view can also be set with mouse (move, rotate, zoom). Similar to manual but with one big difference that camera will move with the vehicle (first vehicle on the list if there are more than one). Camera will move with the vehicle but will not rotate with it.
  • Follow car view can also be set with mouse (move up and down and zoom). In this case the view will follow the car and also rotate with the car. By default the camera will be at the back of the car following it like in driving simulation games. It’s suitable for driving assistance when following virtual routes.

2. Vehicle presentation



Vehicle can be visualized with a 3D model (Vehicle) or as an exact size rectangle on the ground (Exact sized box).

Attitude indicator is a visual control that helps us graphically present the measured altitude.




Modal circle visual control is used when you want to get resonances exact frequency and damping factor. The method Dewesoft X is using, is based on the well-known circle-fit principle. The FFT lines to the right and the left side of a peak (so called “neighbour lines”) are drawn by real and imaginary part in the complex coordinate system. A circle is aligned between them with minimum error to each point and the resonance frequency is approximated

The modal circle can be calculated in two different ways:

From cursor channel - the frequency of the peak is taken from the position of the cursor channel (yellow cursor).

Manual - the frequency is inserted manually by a user. With peak search, we define the bandwidth of the interval in which the resonant peak is searched. If the central frequency is 260,00 Hz and the search range is +/- 10 Hz, it will search for the resonant peak from 250 Hz up to 270 Hz.

Neighbour count defines the number of neighbourhood lines in the FFT. By changing the neighbour count, you can select how many FFT lines left and right from the peak are taken into calculation.

If the resonant peak is not found near the cursor channel or the manually inserted frequency, we get a warning instead of a drawn circle.
