Electrical Specifications
Accuracy is ± (% reading number of digits) or otherwise specified, at 23 ° C ± 5 ° C & less
than 75% relative humidity. True RMS voltage accuracies are specified from 5 % to 100 % of
range or otherwise specified. Maximum Crest Factor < 1.4 : 1 at full scale & < 2.8 : 1 at half scale,
and with frequency components within the specified frequency bandwidth for non-sinusoidal
waveforms.
