Accuracy
Refer to the “Specifications” section for operating conditions and temperature coefficient.
Accuracy is specified as follows: ± (a percentage of the r 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: 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 < 2.1:1 at full scale
•
Crest factor < 4.2:1 at half scale
