AC Conversion Type :
71 :
Average sensing rms indication.
72 / 73 :
AC conversions are ac-coupled true rms responding, calibrated to the
sine wave input.
*The basic accuracy is specified for a sine wave below 4000 counts. Over 4000
counts, add 0.6% to the accuracy. For a non-sine wave, the crest factor of the
waveform is specified at
≦
3 at full scale up to 2000 counts, decreasing linearly to
a crest factor
≦
1.5 at 1000 counts. Add
±
1.5% for a non-sinusoidal waveform.
Crest Factor (C.F.) is the ratio of Peak value to RMS value.
