Connections
Please ensure that the PE conductor (earth) is connected
to the multimess D9-PQ.
Ensure that measurement cable E is connected for each measurement. This is
normally the earthing point of the voltage transformer.
Ensure that switching (3-wire) is selected. (Setting via display or software)
Set the voltage transformer ratio
Enter the nominal conductor-conductor voltage
Set the current transformer ratio
Note
Connecting multimess D9-PQ Power IN in a 3-wire grid
If in a 3-wire grid power is connected to the IN input, it will be calculated and
recorded.
The values measured for IN are not included in the 3~ power calculations. It
is, therefore, possible to use the multimess D9-PQ to capture any additional
current via the fourth power input.
