±(0.5% of reading + 5 counts)
Normal Mode
Rejection, typical
Rejects AC signals by >60 dB at 50 Hz or 60 Hz (user selectable)
Common Mode

AC Voltage
Conversion Type AC conversions are true RMS. The AC measurement is based
on the AC and DC components of the signal as shown below:
AC Measurement = RMS(AC+DC) – DC
