˙ Accuracy is ± (% reading + number of digits)
˙ Ambient temperature: 23°C ± 5°C (< 80% RH)
˙ For the best measurements, with REL Δ function to
compensate for offsets.

Input Protection : 1000V
DC
Input Impedance : 10MΩ, < 100pF
Bandwidth : 40Hz to 10kHz
Minimum Resolution : 1µV in the 50mV range
CMRR / NMRR (Common / 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 AC accuracy.
For Crest Factor of 2.0 to 2.5, add 2.5% to AC accuracy.
For Crest Factor of 2.5 to 3.0, add 4.0% to AC accuracy.
AC+DC Accuracy : AC accuracy + DC accuracy + 1.0%
HFR Accuracy : AC accuracy + 1.0% for 40Hz to 400Hz
The Cut-Off Frequency of HFR : 800Hz (-3dB point)
Attenuation Characteristic of HFR : Approx -24dB
