AC Conversion Type: 61-320: Average sensing rms indication.
61-322 / 61-324: AC conversions are ac-coupled, true rms responding, calibrated to
the sine wave input.
* The basic accuracy is specified for sine wave below 4000 counts. Over 4000 counts, need to add 0.6% to the
accuracy for non-sine waves below 2000 counts, refer to the following for accuracy:
Crest Factor (C.F.):
+1.5% addition error for C.F. from 1.4 to 3
+3.0% addition error for C.F. from 3 to 4 where C.F.=Peak / RMS
