Over voltage protection :
1000 V DC or 750 V ACrms.
Input Impedance :
10 MΩ // less than 100 pF.
* CMRR / NMRR : (Common Mode Rejection Ratio)
(Normal Mode Rejection Ratio)
VAC :
CMRR > 60 dB at DC, 50 Hz / 60 Hz
VDC :
CMRR > 100 dB at DC, 50 Hz / 60 Hz
NMRR > 50 dB at DC, 50 Hz / 60 Hz
AC Conversion Type :
Average sensing rms indication.
AC conversions are ac-coupled, true rms responding, calibrated to the sine wave
input. * The minimum LCD reading is 1400 count in Auto Ranging Mode.
Crest Factor : C.F. = Peak / Rms
+ 1.5% addition error for C.F. from 1.4 to 3
+ 3% addition error for C.F. from 3 to 4
