Power measurement feature
Voltage measurement range and the display digits
The active power is displayed in units of W. For apparent power and reactive power, read the
unit “W” in the following table as “VA” and “var,” respectively.

1 Under the following conditions: within the effective input range, within six months after the last calibration,
at a temperature of 23 °C ± 5 °C, sine wave, power factor of 1, and common mode voltage of 0 V.
If the waveform is asymmetrical (waveforms such as half-wave rectified waveforms and full-wave rectified
waveforms), errors will occur.
2 When you are using the 5 mA range and the input is less than 10 % of the range, add (0.1 % of range).
