Voltage input impedance is all around 1 OMO.
Maximum voltage input: 600Vrms.
• Display true virtual value. Frequency response: 45-400Hz
• Accuracy assurance range: 5-100% measuring range, with less than 10 residual counts allowable in case of
short circuit.
• The following deviation shall be added to calculate non -sinusoidal wave based on crest factor:
a)Crest factor is 1-2: add 3%.
b)Crest factor is 2-2.5: add 5%.
c)Crest factor is 2.5-3: add 7%.
