Overload ............................................................. 600 mA for 2 minutes maximum
Fuse Protection for mA Input .............................. 0.44 mA, 1000 V, IR 10 kA
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 up to 300 mA, decreasing
linearly to crest factor
≤
1.5 at 600 mA. For non-sinusoidal waveforms add
+(2 % r 2 % FS) typical, for a crest factor up to 3.
