Specifications are valid from 5 % to 100 % of amplitude range.
AC conversion: true rms
Maximum crest factor: 3 (between 50 and 60 Hz)
For non-sinusoidal waveforms, add (2 % reading + 2 % f.s.) typical
Input impedance: 10 M (nominal), < 100 pF, ac-coupled
Common mode rejection ratio: > 60 dB at dc, 50 Hz, or 60 Hz
