CMRR / NMRR: (Common Mode Rejection Ratio) (Normal Mode Rejection Ratio)

VAC: CMRR > 60dB at DC, 50Hz / 60Hz

VDC: CMRR > 100dB at DC, 50Hz / 60Hz NMRR > 50dB at DC, 50Hz / 60Hz

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:
