CMRR/NMRR

(Common mode rejection ration/normal mode rejection ratio)

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

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

NMRR >50 dB at DC, 50 Hz/60 Hz

AC conversion type:

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 non-sine waves below 2000 counts, refer

to the following for accuracy:

±1.5% addition error for C.F from1.4 to 3

Crest factor: C.F. = Peak/rms
