QUICK MEASUREMENT CHECK

12.1

Voltage

Switch off power supply.

Connect a single phase voltage to terminals 41 and 42 (VA voltage) and set to 0 V.

Switch on power supply and set as before. Switch on the AC voltage.

Press

once,

twice,

once to read the magnitude of the voltage on phase A.

Raise the voltage to rated volts. The LCD will show the voltage measurement in

primary volts : divide by the set ratios to check accuracy.
