One-year accuracy (accuracy up to 12 months after calibration) | 1.5 times the reading errors for the accuracy at 6 months |
*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).
