Installation and Operation

1. Switch on your DEWETRON measurement device.

2. Use the provided DEWETRON OXYGEN Installer if not installed already.

3. Start the OXYGEN measurement software (if not automatically).

After startup, you see the following measurement screen:

Fig. 1 Screen Area

1	Open screen overview	2	Instrument area
3	Action Bar	4	Menu

This is the “main” screen of the instrument to operate all measurements, readings, recordings and settings. There is not only one screen, you can define a couple of them, each with different instruments and views to stay focused during the measurement application. To open the Screen Overview, just click or slide 1. The Instrument Area 2 is the place, where you can drag’n’drop all different instruments (recorder, scope, digital meter, gauge, power instrument…) and arrange them as you like. All actions can be performed in the Action Bar 3 to start/stop a recording, load and save data and configuration setups. The bar on the right side is the Menu Bar 4 contains the settings in logical groups.

Functional Check

For a quick functional check and first measurement experience, use a test cable (mains plug with to safety banana plugs) and test voltage magnitude.

1. Switch on your DEWETRON device.

2. Connect the mains plug of the test cable to a wall socket and the banana plugs to an voltage input of the DEWETRON device.

3. Navigate to the channel list on the screen 19 or 21.

4. Set Samplerate to at least 100 kHz.

5. Press “Create Power Group” button 39.

6. Select the Wiring Type 1P2W in the selection above.

7. Drag’n’Drop the Voltage Input channel into the U1 Field.

8. Drag’n’Drop Current Input channel into the I1 Field.

9. Check mains voltage in the preview.

Fig. 6 First Setup

Attention

The green highlighted box is the actually selected synchronisation source.

Note

Make sure, that you use only an appropiate isolated input channel. Examples for this are TRION(3)-POWER and TRION(3)-HV boards.

Setting up sensors

To make properly measurements, the sensor scalings (e.g. current transducers) have to be set correctly. In the most cases, the sensor label gives information about the input/output scaling. This value is often known as “transducer factor”, “ratio” or “sensitivity”. Important is the unit of the scaling, e.g. 20 mV/A or 50 A/V or 1:50. The order to input the correct scaling is the following:

• Click/Touch the “Scaling” field of the concerning channel 35.

• The Channel Scaling pops up to change the defaults.

• Change the unit to the primary measured unit (e.g. A for Amps).

• Enter the scaling value directly if given in the shown unit (e.g. A/V).

• If the sensitivity is given, select the sensitivity button and enter the value.

Arrange Instruments

Now it is time to launch the measurement.

1. Leave the channel setup by pressing 19 (or sliding 21)

2. Clear the screen by opening the instrument selector 22 and pressing the button “Clear” at the bottom.

3. Create an instrument (e.g. Power Instrument) by changing to the channel list (press 21) and drag’n’drop the PowerGroup channel onto the instrument area (Default Name of PowerGroup is POWER/Number).

4. Arrange and resize the instrument for a good view.

5. Add another instrument by moving to the instrument list 22 and drag’n’drop an item to the screen.

6. Append Channels by selecting them from the channel list 21.

Power Instrument

You can also add other instruments to the screen, simply by drag’n’drop. To add a channel to specific instruments, just select them in the channel list and drag’n’drop on the instrument. Or simple select the instrument first and assign channels afterwards by selecting them in the channel list.

Power Screen Templates

Fig. 9 Power Templates Setup

1	Open Screens	3	Select Power Module Template
2	Add predefined item	4	Add Power Screen Template

Adding the predefined PowerModule for a Power Group will add a new measurement screen with a prearranged group of instruments. This is available for each created Power Group in your setup. Templates are available for each wiring type.

Fig. 10 Power Templates Screen

1	List display of the power instrument	3	Voltage Chart Recorder in Range of 10 seconds
2	Vector diagram of the power instrument	4	Current Chart Recorder in Range of 10 seconds

The Power Templates always consist of a group of 4 instruments. The top 2 instruments are displaying the calculated power values in list and vector form. The bottom two instruments are displaying the raw waveforms of voltage and current in chart recorders. The voltage signals and the current signals are displayed in one chart recorder respectively. The signals are displayed in a time range of 10s and automatically scaled to fit to the value-axis. The two chart recorders are linked, so scrolling in one recorder to change the time scale will also affect the other recorder in the same way. Double clicking on any instrument on the template measurement screen will open the Instrument Group Settings. You can change the Instrument Group display name, visible on the top center of the screen and you can dismantle the group into each separate instrument. After dismantling the Group it is possible to resize and rearrange the instruments as well as changing individual instrument settings.
