Voltage Measurement Specifications (U: Displayed as V on panel display)
Effective measuring range Voltage: 1% to 150% of the range (1,000 V range, up to 1,000 V)
Current: 1% to 150% of the range
Active power: 0% to 225% of the range (when using 1,000 V range, up to 150%)
However, valid when the voltage and current fall within the effective
measurement range.
Other parameters: Valid within the voltage, current, and active power effective mea-
surement range.

within range in which the fundamental wave satisfies synchronization source
conditions
Temperature coefficient ±0.03%f.s. per °C or less. However, for 1 mA range, ±0.06%f.s. per °C or less.
Effect of power factor ±0.1%f.s. or less (45 to 66 Hz, at power factor = 0)
Internal circuitry voltage/current phase difference: ±0.0573°
Effect of common mode
voltage
±0.01%f.s. or less (600 V, 50 Hz/60 Hz, applied between input terminals and enclosure)
Magnetic field interference 400 A/m, DC and 50 Hz/60 Hz magnetic field
Voltage ±1.5%f.s. or less
Current ±1.5%f.s. or below value, whichever is greater, or less
200 mA/ 500 mA/ 1 A/ 2 A/ 5 A/ 10 A/ 20 A range: ±20 mA
1 mA/ 2 mA/ 5 mA/ 10 mA/ 20 mA/ 50 mA/ 100 mA range: ±200 A
Active power ±3.0%f.s. or below value, whichever is greater, or less
200 mA/ 500 mA/ 1 A/ 2 A/ 5 A/ 10 A/ 20 A range:
(Voltage influence quantity)×(±20 mA)
1 mA/ 2 mA/ 5 mA/ 10 mA/ 20 mA/ 50 mA/ 100 mA range:
(Voltage influence quantity)×(±200 A)
Effect of self-heating With input of at least 15 A to current input terminals
Current AC input signal
±(0.025+0.005×(I-15))%rdg. or less
DC input signal
200 mA/ 500 mA/ 1 A/ 2 A/ 5 A/ 10 A/ 20 A range
±((0.025+0.005×(I-15))% rdg.+(0.5+0.1×(I-15))mA) or less
1 mA/ 2 mA/ 5 mA/ 10 mA/ 20 mA/ 50 mA/ 100 mA range
±((0.025+0.005×(I-15))% rdg.+(5+1×(I-15))A) or less
I: Current read value (A)
Active power (above current influence quantity) × (voltage read value) or less
The effects of self-heating will continue to manifest themselves until the input resistance
temperature falls, even if the current value is low.
Measurement types Rectifiers: AC+DC, DC, AC, FND, AC+DC Umn
Effective measuring range ±1% to ±150% of the range.
However, up to ±1,500 V peak value and 1,000 V RMS value
Display range Up to ±152% of the range. However, zero-suppression when less than ±0.5%
Polarity Displayed when using DC rectifier
Over-range display Displays [o.r] (over-range) when input exceeds ±152% of the range or ±1,060.5 V.
Peak exceeded warning The PEAK OVER U lamp will light up for which the input voltage peak value exceeds
±1,500 V or ±600% of the range.
