Over voltage protection : DC1000V or AC 750 Vrms.
Input Impedance : 10MΩ // less than 100pF.
CMRR / NMRR : (Common Mode Rejection Ratio)
(Normal Mode Rejection Ratio)
V : CMRR > 60dB at DC, 50Hz / 60Hz
AC
V : CMRR > 100dB at DC, 50Hz / 60Hz
DC
NMRR > 50dB at DC, 50Hz / 60Hz
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 a
non-sine wave, the crest factor of the waveform is specified of
≦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.
