Accuracy
See the Specifications section for operating conditions and temperature coefficient.
Accuracy is specified as follows: ± (a percentage of the reading + a fixed amount)
at 23 °C ± 5 °C (73.4 °F ± 9 °F), 0% to 75% relative humidity. Specifications are for 50,000
counts mode.
True RMS Readings: True RMS voltage and current accuracies are specified from 5% to 100%
of the range unless otherwise specified. Frequency must be within the specified bandwidth for
non-sinusoidal waveforms. Crest factors are as follows:
• Crest factor < 5:1 at full scale
• Crest factor < 10:1 at half scale
