AC conversion: Inputs are ac-coupled and calibrated to the rms value of sine wave input. Conversions
are true-rms responding and specified from 5 % to 100 % of range. Input signal crest factor can be up to
3 at up to 500 V, decreasing linearly to crest factor <= 1.5 at 1000 V. For non-sinusoidal waveforms add
± (2 % reading + 2 % FS) typical, for a crest factor up to 3.
Input impedance: 10 MΩ (nominal), < 100 pF, ac-coupled
Common mode rejection ratio (1 kΩ unbalanced): > 60 dB at dc, 50 or 60 Hz
Overload protection: 1000 V rms or dc, 10
