16. RMS voltage measurement specications Urms
Measurement method Measured during the 200-ms aggregation period in accordance with IEC61000-4-30
When set to 3P3W3M or 3P4W (or 3P4W2.5E [available after the rmware update]),
the phase voltage and line voltage setting is applied to the RMS voltage, Urms
Displayed items RMS voltage on each channel
AVG (average) RMS voltage on multiple channels
(For details, see Calculation Formula.)
Display selection Phase voltage/line voltage (When 3P3W3M/3P4W/3P4W2.5E [available after the
rmware update] are set, both will be stored)
Measurement range 1000.0 V
Measurement accuracy With a voltage of between 10 V and 660 V input: ± 0.2% of the declared voltage input
(at a declared input voltage of 100 V to 440 V but with a voltage of between 10% and
150% of the declared input voltage input)
With a voltage other than above input: ±0.1% rdg. ±0.1% f.s.
17. Voltage DC value measurement specications Udc
Measurement method Average value of the values obtained during the 200-ms aggregation period
Displayed items Voltage DC value

Displayed items Voltage CF Value
Measurement range 224.00
Measurement accuracy Accuracy not dened
19. RMS current measurement specications Irms
Measurement method True RMS method
Measured during the 200-ms aggregation period based on IEC61000-4-30.
Displayed items RMS current on each channel
AVG (average) RMS current on multiple channels
(For details, see Calculation Formula.)
Measurement range Depends on the current sensor in use
Measurement accuracy ±0.1% rdg.±0.1% f.s. + (current sensor accuracy)
(Note: While using 2000 A range of Model CT7742, f.s. tolerance should be 2.5 times
the value)
