Wiring test

The wiring test checks whether the multimeter has been installed correctly.
Requirements
In order to run the wiring test, the multimeter must be connected to an active system and the
following conditions must be fulfilled:
● Three-phase system with all phases (V > 50 V AC PH-N)
● Minimum current flow in each phase (> 1% of current transformer)
● Positive flow of energies (normal system in which the inductive load draws power from
the supply)
Run wiring test
1. Call up the command menu. You can find more information in chapter Command menu
(Page 36).
2. Select command C.16 as described in the instructions in chapter Command menu
(Page 36).
3. Check the following points:
– Reading of the three voltages
– Phase sequence
– Voltage unbalance
– Reverse polarity of one or more current transformers
– Mismatch between voltage/current phases
If the test is not successful, the display indicates the reason why it has failed.
