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
