Display settings

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

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 revision and analysis of this data.

In Dewesoft X, we can set up different screens in Acquisition section in Measure label.

Dewesoft X allows us 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.

All controls can be combined in 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 and own specific displays can be created with different appearance.

All Dewesoft X pre-defined and added displays can be adapted to meet the user's requirements and to have a simple and efficient overview of your signals and measurement. Pre-defined display is excellent starting point to create your own display with different appearances of acquired signals on screen with:

Add instruments

Dewesoft X provides some default screens with pre-defined displays of different instruments for each input:

  • Recorder
  • Scope
  • FFT analyser
  • Modal test
  • Order tracking
  • Torsional vibration
  • Balancing
  • Power
  • Fatigue analysis
  • Sound Power
  • .......

These instruments are built as a jump start that software acts like a classic instruments like strip chart recorders, classic oscilloscopes and so on. Some of the following pre-defined displays - screens:

Name of pre-defined displayIconDescription


Scope - oscilloscope screen has predefined one Scope instrument, which is
usually used for displaying fast, short-time events. Like in a traditional scope
you can define trigger conditions.


Recorder screen has predefined the recorder instrument displays for all of the
active channels by default. This screen is meant to display the time -history
plotting capabilities and to get an idea of the acquired signals over a long time -


Custom screen is intended to be defined and supplemented by the user with adding
and arranging instruments.

FFT analyser

FFT display (Fast Fourier Transformation) screen has predefined FFT and
one scope instrument displays for the all of active channels by default (each
graph can display up to 4 signals). The basic idea of the FFT display is to display
the frequency components of your acquired data.

Power grid analysis

Power display screen has predefined Vector scope of selected signals and
one scope instrument displays for the all of active channels by default. The
basic idea of the power display is to display the voltage and current as well
as the phase between them.


GPS screen has predefined GPS display, digital meters for GPS channels and
one recorder instrument display. The basic idea of the GPS screen is to
observe a graphical representation position data together with a display
acquired values in digital meters and a recorder view for time domain display
of acquired data.

With a completely new setup, there are only few displays which are added. These are Recorder, Scope and Custom.

Additional predefined displays can be added by selecting the display icon. We type the name, and select an icon.

A new predefined display can be added by choosing from display templates. Here all the standard displays named above are shown.

These screens can be altered to meet the user’s requirements and arrange them freely in front of any graphic in your system to have a simple and efficient overview of your signals and measurement.

When you press the Design button  or when selecting Design mode from the menu bar, design mode is selected and you are allowed to create your own display - appearance of channels data on the screen.

After you press Design button, next to this button 'Add instrument' design tool bar appear.

As soon as you enter any Pre-defined display screen, you can enter the Design mode.

Important: When you have finished the adaptation, please press the Design button again to fix the layout, otherwise you won't have the full functionality of the instruments.

After you press Design button again, design mode tool bar disappears.

All pre-defined displays can be adapted to your own requirements with:

- Shown predefined standard instruments for selected pre-defined display (and for all used channels) on the lower right part of this screen
- Control properties and Design tool button on upper left part of this screen to enter Design mode - Add instruments for this type of display with button on "add instrument" design tool bar
- Instrument setting on middle left part of this screen
- Assigning channels to new instruments with channels selector on right part of this screen
- Using additional screen edit function on design tool bar of this screen and Displays menu edit display option
- Instrument appearance setting: position, size, grouping,...

To add an visual control to your display, after selecting Design mode just click on the desired icon on "add visual control" design tool bar, described at Instruments setup.

Every time when you click on the visual control icon, a new visual control will be added at the left-top corner of the visual control area.

You can add visual control according to your requirements. Due to the flexibility of the Dewesoft X display screens, you can arrange the visual controls according to your requirements with nearly no limitation.

As a standard, channels will be automatically assigned to new visual controls. But usually you don't want these channels to be in the new instrument and you want to reassign another channel.

Make sure that the new visual control is still selected - this is indicated by a white box around the selected visual control. If it is not selected, click on it once more. Then click on any input from the Channel selector on the right side of the screen to assign this channel to the new instrument.

Some instruments like the Recorder, Scope and FFT allow more channels assigned to one graph.

To reassign any instrument from one channel to another, first click the instrument to select it, then unclick the currently selected channel from the Channel selector (depending on instrument type, it will display unassigned or simply remove the channel), then click on any other channel from the Channel list.

You can have the same channel assigned to multiple instruments if desired.

Dewesoft X offers a very powerful and flexible Channel selector. It can display the available channels as already known in a channel list or in a grouped form.

Channel selector offers the following capability:

Channel (list) view / Group view- different view on all used channel selector
Select / deselect channels- assign or reassign channels to visual controls

Channel (list) view / Group view

When you select the Group view, channels will be grouped according to its source. We will have groups for analog input (AI), counters (CNT), Math and other math modules. We can see the channels by expanding the group simply by clicking on it.

Another view of the channels is the channel list view. Here the channels will be listed in alphabet order regardless of its source.

A third view is the list of all selected channels (right side below). This will show the channels which are currently selected on the display. This provides an easy way to deselect channels for current display by simply clicking on each item.

If there is only one hardware group available (e.g. Al) the channels are always displayed in List view!

Select /deselect channels

The channels, which are shown on currently selected visual control can be selected by clicking on the channel. If the channel is already on the visual control, it will be marked and clicking on it will remove it from visual control.

There are several other ways to assign channel to visual control. We can drag and drop the channel to the visual control. When we click and hold the left mouse button, channel will be selected and we can drag it over to any visual control. We can drop it to any place and that will add the channel to the display or we can drop it on the display's channel list to replace the channel. In the example below the CNT2/Angle will be replaced with the AI1/FFT block count.

In Design mode we can drag and drop channel to empty place on the display. This will add new visual control from the type currently selected on the Design bar and automatically assign the channel to it.

Searching for channels

Dewesoft X setups can easily have hundreds and even thousands of channels. To find channels we have added a feature to search for them by the name. If we enter the keyword in Search field, Dewesoft X will look for channels with those keyword in the name (at any place) or the channels connected to the keyword (output channels of different math modules). We can cancel the search by pressing the X button on the right side of the search bar.

Additional settings in analyse mode

In the Analysis mode the list is expanded and we can change the color of the channel, rename the channel or add any math from the channel selector:

  • formula
  • filtering (IIR, FIR, frequency domain filter)
  • time domain analysis (intergral, derivarive, scope math, latch math, delay channel, ...)
  • statistics (basic, array, classification)
  • frequency domain analysis (FFT, STFT, octave, cepstrum)
  • machinery diagnostics (CA, angle sensor math, envelope detection, tracking filter, ...)
  • counting
  • constant (from current value)
  • PID control
  • reference curve
  • acoustics (weighting filters, RT60)

Available channels are dependent from the type of the selected channel in analysis mode.

For example, when we want to add a filter to any channel, right click on the channel and select Add Math -> Filter.

The filter window will be opened and the channel which was selected will be automatically chosen.

If selected channel source is math, then we have additional two options to edit the math function or to delete the math function.

When you have to display dozen of channels in many elements - instruments, you must arrange them for clear appearance:

- position of the elements
- size of the elements
- define the transparency of the element

Make sure that your instrument is selected (simply click on the element to select it, a white box around it will indicate the selection).

Now you have two possibilities:

  • Drag the element and drop it where you need it
  • Use the arrow keys to move it in the desired direction

Tip: use the SHIFT key simultaneously with the arrow keys to increase moving speed.

If the element comes in conflict with other elements, you can bring the element in front of the other one or behind it; therefore right-click on the element and then select Bring to front or Send to back from the appearing menu list.

You can define the size of your instrument completely free. Note that you have 8 handles around the visual control.

We can adjust the size of the control with dragging those handles. When the instrument is selected, simply click on one of the six white boxes at the outline of the instrument (the cursor will change to double arrow ), keep the mouse button pressed and move the mouse into the desired direction.

We have now defined the instrument, its channel(s), size and its position. But what to do when instruments overlap one another?

Dewesoft X offers a transparency for each element, which can be set to:

  • None,
  • 25%,
  • 50%,
  • 75% or
  • Full transparency.

The transparancy of the visual control can be set in two ways:

  • use the Transparent checkbox in the Control properties bar and select the transparency value from the drop down list 
  • right-click on the desired element, select Transparency and the desired value from the appearing menu

The following example should give you an impression of the transparency function - the Digital meter transparency has been set to 100%.

Full screen

Active online display screen can be enlarged on full Dewesoft X window by pressing Ctrl + F. To escape from this mode press ESC button (or Ctrl + F) on your keyboard.

Add new display

Displays can be managed by choosing the display icon.

If we want to create standard display, then we can choose it from template list.

If we want to create just an empty display, then Custom template must be chosen.

We can add the display as main display.

This will add a new screen right next to the selected display on the display menu bar.

We can also add the display as a sub display.

This will add a new display as a child item of currently selected screen. The display icon will get a drop down button to change the currently shown display.

Then we can change the name and icon by changing Display properties. Name of the displays can be changed by entering a new name in the Display name field. Icon of the display can be changed by setting one of the standard icons or by selecting any file when choosing the Custom item from the Icon dropdown and then selecting any image file. Note: 32x32 is the best resolution for custom icons.

We can also move display left or right by choosing the Move left or Move right button.

Remove display

Selected display can be deleted with selecting Remove display option from the Remove menu.

Dewesoft X offers a Design Control properties to create a complex view off all the acquired and calculated data on the online display screen.

With the Control properties, Dewesoft X allows creating, arranging and grouping of different elements:

  • Define the number of columns in a group.
  • Add / Remove instruments to/from group
  • Adjust the transparency of instruments
  • Define Unified properties (different settings for each instrument)
  • And in some cases, switch between a single and multi-axis.

Columns number in group

Placing each instrument individually on the display can take some time, especially when you have to display dozen of channels. Therefore, Dewesoft X allows creating instrument groups, which are boxes with the same sort of instruments. With the Cols drop-down list, you can define how many columns of instruments should be allowed in a group. You can select a predefined number of columns or enter a custom number up to 10.

Add/Remove instrument to/from group

Sometimes you might require more instruments on one display. After defining the column number, simply press + button to add or - to remove the instrument from the group and from the display.

You can even press the small "arrow" button to quickly define number of instruments group.

Unified properties

As a standard, all instruments within one instrument array (group) have the same properties. For example, all digital meters within an array are set to 50% transparency, show the peak-peak value with very slow (5s) average time.

Untick the Unified properties check box to allow different settings for each instrument within the selected group. In our example now you can set e.g. AC RMS value for the first instrument, RMS for the second, MIN for the third and MAX for the fourth.

Dewesoft X offers an additional screen edit function to create intelligible display all channels data on the screen.

Instruments appearance- arrange elements - instruments with positioning, size and define
Common function- to copy & paste, delete and undelete elements
Additional controls- to illustrate your measurement with background picture; to write text on the
screens with text element; to draw lines and shape, connect different
elements with line element

Copy and paste existing group of instruments

You can use the Copy function to create a new group or an element. The new elements will have exactly the same settings and can be edited as all other.

To copy the element, right-click on the element and select Copy group to clipboard from the menu list:

Then move the cursor to the desired position (must be on screen outside group), right-click again and select button Paste.

That’s all - the new element is available with the same settings and applied channels.

Delete instrument

You may want to delete the instrument from the display screen. To delete any instrument, just click it once to select it, and then click:

The Delete instrument button on Design mode tool bar or press the Delete button on your keyboard.

IMPORTANT: When one instrument in group is selected with using this function,whole group will be deleted!

Undelete instrument

If you have deleted an instrument from the display screen and want to undo that select Undelete from the Edit menu.

IMPORTANT: Be aware, that this function works only for the last deleted instrument!

Dewesoft X offers two different time base types for multiple graphs: single time axis or multiple time axes.

Tick the Single time axis checkbox to change between these two modes.

Single time axis

The advantage of the single time axis is to have more space to display the data.

Multiple time axis

The advantage of the multiple time axes is to make it easier to read time related information.

Time axis type

You can show either absolute or relative time in the Time axis type (in case of the Vertical recorder in the vertical direction) for each graph. Click on any graph to select it and then use the selector to make your choice.

  • Relative - elapsed time since recording or monitoring began 
  • Absolute - current date and time; this format is compatible with the timing information according to UTC 
  • Absolute (time only) - current time only 
  • Absolute (day+time) - day in year and current absolute time

Grid resolution

To make the analysis more comfortable, Dewesoft X contains the possibility to change the number of grid lines in the recorder display.

Depending on the range and signal, it may be more practical to change the number of grid lines in Y axis ticks from 2 (default) to 8 - or remove them completely.

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 the Display type drop down list (Different setups will give you a different numbers of display types).

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

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 also represents 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, display will reduce the data continuously according to the static/reduced rate selected in STATIC/REDUCED RATE drop down list in the channel setup.

Upper & Lower limit

You can set high and/or low alarm limits for each instrument, which will cause the instrument numbers to change from green to red when it is either above the high limit or below the low limit (colors can be easily adjusted).

If you want to use limits for an instrument, select it by clicking on it once. Check the Use 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 rises above 330 deg or changes to yellow when it falls below 200 deg, we set this meter up accordingly (see picture above).

Note: 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 color simply click on the colored 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 of the Alarm monitoring function.

Minimum and maximum shown value

You can define a Minimum and a Maximum shown value for the bar graph; this feature is very important for better scaling on the display. For example, your angle measurement range is from 0° to 360°C.

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

Run mode - Time axis scaling

IMPORTANT: This way of changing Time axis can't be done in Design mode - it is available only in Run mode.

Use the blue plus and minus symbols to expand or compress the time axis.

Clicking minus will show more time across the graph. You can show the entire length of the recording, regardless of how long it is! Even days and days of data can be shown here.

By unchecked Single time axis - the multiple times axis, this control appears for each graph. Appearance and functionality by vertical instruments are same, except time axis is vertical.

Y-axis scaling/auto scaling

IMPORTANT: This way of changing Y-axis can't be done in Design mode - available only in Run mode.

If you want to change the Y-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 extremes and then type in a new number. This is possible when the cursor has the following appearance: A grey outlined box around the scale value indicates the selected channel.
  • Auto scale Move cursor to the axis scale. If you have reached the auto scale area, the cursor changes to the following appearance: A gray outlined box around the scale value indicates the selected channel. Press the left mouse button to activate auto-scaling for this channel or press the right mouse button to undo auto scaling. The auto-scaling function always calculates the minimum and maximum value of the currently displayed signal and uses 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 (it only works in the area left of the graph, where the scale is):

Left mouse button

Auto scales the selected channel (see also above).

<CTRL> + Left mouse button

Selects all available channels and scales all channels to the same maximum and minimum (highest and low estimated value within all channels).

<CTRL> + <ALT> + Left mouse button

Selects all available channels and scales each channel to its own maximum and minimum.

<SHIFT> + Left mouse button

Scales the selected channel symmetrical around zero (± values are the same).

<CTRL> + <SHIFT> + Left mouse button

Scales all available channels symmetrical around zero (all ± values are the same)

<CTRL> + <SHIFT>+ <ALT> + Left mouse button

Selects all available channels and scales each channel symmetrical around zero (each channel to its ow n ± value).

Right mouse button

Undo auto scale for the selected channel (see also above).

<CTRL> + Right mouse button

Selects all available channels for undo auto scale.

Note: Displaying X and Y axis information described this way can't be done in Design mode - available only in Run mode.

If you move the mouse cursor over the signal, a white cross appears, showing the current position of the measurement cursor. As soon as you stop moving the mouse or trackball, the cursor will fix its position on the signal and move with the time. The cursor readout is displayed above the graph and shows:

X axis informationThe absolute or relative time at the cursor position, depending on the selected axis type
Y axis informationThe signal value at the cursor position, including units.

As one graph may contain up to four signals, the measurement cursor always tracks the nearest signal next to the current position.

Appearance and functionality of vertical instruments are the same, except:

- Y-axis information is absolute or relative time at the cursor position
- X-axis information is the signal value at the cursor position
- the cursor readout is displayed below the graph

NOTE: The measurement cursor is not available when the time base is set to a short time. It's only working for long time measurements.
