CONNECTION TEST
– The connection test permits verification of the correct installation of the multimeter.
– In order to run the test, the multimeter must be connected to an active system with the following conditions:
• three-phase system with all phases present (V > 50VAC PH-N)
• minimum current flow in each phase > 1% of the CT full scale set
• positive flow of energies (i.e. a normal system where the inductive load draws power from the supply)
– To launch the test, enter the commands menu and select command C.16, according to the instructions in the Commands Menu section.
– The test permits verification of the following:
• reading of the three voltages
• phase sequence
• voltage unbalance
• reverse polarity of one or more CTs
• mismatch between voltage/current phases
– If the test is not passed, the display shows the reason for the failure.
