Accuracy is ± (% of reading number of digits) or otherwise specified, at 23 C ± 5 C & less than 80%relative humidity.
True RMS voltage & current accuracies are specified from 1 % to 100 % of range or otherwise specified.
Maximum Crest Factor < 1.70:1 at full scale & < 3.4:1 at half scale, and with frequency components fall within the specified frequency bandwidth
for non-sinusoidal waveforms.
