Accuracy
Refer to 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.
True RMS Readings: Voltage and current accuracies are specified from 10% 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 < 3:1 at full scale•
Crest factor < 6:1 at half scale•
