1-3 Electrical Specifications

Accuracy is ± (% reading + number of
digits) at 23°C ± 5°C < 80%RH.
Temperature coefficient :
Add 0.2 x (Specified accuracy) / °C, < 18°C,
> 28°C .

V
400~750Vrms 50Hz ~ 500Hz *1
0~400.0 V
V ±(0.7% + 2 digits)
400~1000 V
*1: For readings of less than 15% of full
scale (4000 digits), add 2 digits to reading.
The settling time will be longer.
Overload protection :
750 Vrms // 1000Vdc
Input impedance: 1MΩ // less than 100pF.
AC Conversion Type:
AC Conversions are ac-coupled, true rms
responding, calibrated to the rms value of
a sine-wave input. Accuracies are given for
sine-wave at full-scale and non-sine wave
below half-scale. 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.
