Electrical Specifications
Accuracy is (% reading digits + 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.
