Electrical Specifications
Accuracy is (% reading digits + number of digits) or otherwise specified, at 23C 5C &
less than 75% relative humidity.
True RMS model 197 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.

Lo-Z DCV Input Impedance:
Initially approx. 2.5k, 600pF nominal;
Impedance increases abruptly within a
fraction of a second as display voltage is
above 50V (typical). Ended up impedances
vs display voltages typically are:
10k @100V
60k @300V
200k @600V
420k @1000V
