For optimal working, we recommend that you install the latest version of Dewesoft. If you already have
Dewesoft installed, please check if a newer version is already available. You can either check on the
website under Support/Downloads/Dewesoft X3 section or directly in software under the Options/Check
for updates. In both cases the changelog is included

First connect the power supply to the connector named POWER IN of your SIRIUS system.
SIRIUS USB: connectors on the rear side
USB cable
Then connect the USB cable to the rear-side of the SIRIUS system (see connector named USB in
Illustration “ SIRIUS USB: connectors on the rear side ” ). Finally, connect the other side of the USB cable to
the USB port of your computer.

3.2.3. Dewesoft settings SIRIUS
The connected device will show up in the Dewesoft settings. Click on the Options button at the top
right, and then on the Settings item in the pop-up to open the Dewesoft settings dialogue.
Dewesoft settings
In the Devices section, you can see the connected SIRIUS device. When you select one of them, the
properties pane at the right will show the related data e.g. Serial number, Firmware version, etc.

3.2.4. Channel setup SIRIUS
When Dewesoft has started up, you will be in the Measure mode and see the Setup files list or you can
create a New setup ❶ . Click on Ch. setup (on the right of Setup files) to switch to the Channel setup
mode ❷ . In the channel setup you can see a preview of the connected devices on the upper left side.

Hint
When you click on a connector in the image the corresponding channel in the Channel setup
grid will automatically be selected. This also works the other way around: when you select a
channel (or multiple channels) in the setup grid, the corresponding connectors in the image will
be highlighted.
The sampling rate will be set for all connected SIRIUS devices: of course only up to the max. sampling
rate of the individual slices.

3.3. Simple measurement
This chapter describes measurement basics, how to configure SIRIUS and gives some details on the
measurement setup.
3.3.1. Help - manual
Note that this document is just a quick start guide. For detailed information about Dewesoft consult the
Manual. To open the manual press the F1 button or click on the Options button ❶ and then select
Manual from the pop-up menu ❷ .
Help - Manual
3.3.2. Analog channel setup
In the analog channel setup screen you can see all channels of your connected SIRIUS systems. Per
default only the first channel will be set to Used. Unused channels will not show up in measure mode
and can thus not be used for display, calculations or storing: thus, we will also set the other channels to
the used. You can left-click on the Used column of channel 2 ❶ , hold the mouse button and move the
mouse down to channel 6 ❷ : then release the mouse button and all channels will be selected – this is
shown by the black rectangle around the buttons. Then you can click into the selected region to toggle
Used/Unused for all channels at once. The selected channels will also be highlighted in the small
preview image of the device ❸ .
When you press the Setup button of a channel (the column at the right edge of the channel table – not
shown in this screen-shot), you can change all the settings of the channel amplifier. You can also
change the sample rate of SIRIUS ❹ .

3.3.3. Sample rate
One of the most important settings is the sample rate. The sample rate defines how many data points
SIRIUS will transfer to the Dewesoft. Higher sample rate also means that more data needs to be
transferred via USB to your computer.
The sampling speed mainly depends on your application. To display your signal in a time domain with a
good time resolution, you should sample 10 to 20 times faster than the frequency of the signal that you
want to measure, e.g. 1 kS/s for a 50 Hz sine-wave. If you have a lot of high frequency components, it may
be necessary to sample 100 times faster, e.g. 5 kS/s for the 50 Hz sine-wave, or even more. If you display
only the frequency domain (FFT analysis), a 2.5 times faster sampling would be sufficient (125 S/s for the
50 Hz sine-wave). The higher the sampling rate, the better the time resolution. But also the file size will
increase.

3.3.4. Measurement mode
A click on Measure (at the right side of Ch. setup in Illustration below) will take you to the Recorder
screen measure mode where you can already see live data.
Hint
When switching to Measure mode the data will not be stored automatically.
Measure mode
In measure mode you can have several measurement screens ❺ . Dewesoft will create 2 default displays:
Recorder and Custom but you can also create new displays or change the widgets on existing displays
as you like.
The most important sections of the Measure mode are highlighted in screen-shot Illustration “Measure
mode”:
❶ shows the live measurement data in different widgets which are depending on the selected
measurement screen. In this case we see a simple recorder widget where data is presented in time
domain. You can use the channel-selector list ❷ to assign measurement channels to the widgets. Each
widget has different settings, ❸ shows the settings of the currently selected recorder widget.
To start storing the data, press the Store button ❹ . When you are done with recording, press the Stop
button.
Now Dewesoft has created a data file with all the data that you have seen during the recording session.
You can now click the Analyse button (on the left-top of the screen to the right of the Measure button)
to go to Analyse mode.
