Check that the meter is connected to the specified voltage and that voltage
phase connections and the neutral (if used) are connected to the correct termi-
nals.
9
For a transformer connected meter, check that the current direction of the pri-
mary and secondary current of the external transformers is correct. Also check
that the transformers are connected to the correct meter terminals.
10
Switch on the power. If a warning symbol is displayed, refer to the error codes
in Troubleshooting.
11
Under the menu item "Instantaneous Values" on the meter, check that the volt-
ages, currents, power and power factors are reasonable and that the power
direction is what to be expected (the total power should be positive for a load
that consumes energy). When doing the check the meter should be connected
to the intended load, preferably a load with a current above zero on all phases
to make the check as complete as possible.
