Measurement Characteristics
Accuracy is ±(% reading + number of digits) at 23°C ± 5°C, less than 80% R.H.
Temperature coefficient: 0.2 × (Specified accuracy) /°C, <18°C, >28°C
Operating temperature: 0°C ～ 30°C (≦ 80% RH)
30°C ～ 40°C (≦ 75% RH)
40°C ～ 50°C (≦ 45% RH)

400.0V 100mV
750V 1V
±(1.0% reading + 5 digits) 50Hz ～ 500Hz 750V rms
Input Impedance：≧1M// less than 100pF.
AC Conversion Type: Reading less Full Scale 15% add 4 dgt.
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.
