NOTE:
Instrument has 3 voltage ranges. Range has to be chosen according to the
network nominal voltage, according to the table bellow.
Nominal phase voltage: U
Nom
Recommended Voltage range
50 V ÷ 110 V
Voltage Range 1: 50 V ÷ 110 V (L-N)
110 V ÷ 240 V
Voltage Range 2: 110 V ÷ 240 V (L-N)
240 V ÷ 1000 V
Voltage Range 3: 240 V ÷ 1000 V (L-N)

Nom
Recommended Voltage range
86 V ÷ 190 V
Voltage Range 1: 86 V ÷ 190 V (L-L)
190 V ÷ 415 V
Voltage Range 2: 190 V ÷ 415 V (L-L)

Voltage Range 3: 240 V ÷ 1730 V (L-L)
NOTE:
Assure that all voltage clips are connected during measurement and logging
period. Unconnected voltage clips are susceptible to EMI and can trigger false events. It
is advisable to short them with instrument neutral voltage input.
