AC Conversion Type: 61-320:
Average sensing rms indication calibrated to the sine wave input.
61-322 / 61-324:
AC conversions are ac-coupled, true rms responding,
calibrated to the sine wave input.

61-322 / 61-324 The specified accuracy is for sine wave at full scale and non-sine wave at half
scale with crest factor up to 2.
Crest Factor:
C.F. = Peak/RMS
+1.5% addition error for C.F. from 1.4 to 3
+3.0% addition error for C.F. from 3 to 4.
