2. To open an existing template (*.vdf), select File > Open.
3. Change all settings according to your requirements.
4. Save the configuration as a template and/or initialize the measurement.
Note
For the initial test measurements, we recommend accepting the default
values for all settings. Based on the initial results, you can then modify the
trigger settings to optimize them.
Hardware Settings
In this settings panel you can adjust all hardware related parameters. The Input
Configuration defines how the signals supplied to the input channels are interpreted by
the instrument. The input configuration is sometimes also referred to as "Measurement
System". For details about the supported measurement systems please refer to the Users
Manual.
There are two additional options related to the input configuration. If you check Current:
IL3 = - IL1 - IL2 the current on channel 3 is not measured but calculated. The main
application is a 3-wire measurement system with only two current transformers, where
the sum of the 3 phase currents equals zero. In this case you can calculate the third
current.
The second option defines which voltages are used as source for event detection, flicker
and harmonics measurement. If the box is checked the parameters are evaluated based on
the phase to phase voltages rather than the phase to neutral voltages.
