Overload .............................................................600 mA for 2 minutes maximum
Overload Protection.............................................440 mA, 1000 V, FAST fuse
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 % reading + 2 % FS) typical, for a crest factor up to 3.
