Accuracy is ±(% reading + number of digits) at 23°C ±5°C < 80%RH.
Voltage Measurement
Function
DCV
ACV
LPF ACV
Initial Voltage: ≥ AC 0.6V.
Over voltage protection: 600 V AC RMS/DC.
The cut-off frequency of the low pass filter: 1 kHz.
Input Impedance: 3MΩ // 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.
For non-sine wave add the following Crest Factor corrections:
For Crest Factor of 1.4 to 2.0, add 1.0% to accuracy.
For Crest Factor of 2.0 to 2.5, add 2.5% to accuracy.
For Crest Factor of 2.5 to 3.0, add 4.0% to accuracy.
