7 Specifications
[1]
Maximum input for specified accuracy = 10 × range or 1000 V.
Frequency sensitivity during current measurement
[1]
For maximum input, please refer to AC current measurement.
[2]
The accuracy for duty cycle and pulse width is based on a
5 V square wave input to the DC 5 V range. For AC coupling, the duty cycle
range can be measured within the range of 5% to 95% for signal frequency
> 20 Hz.
500 V 30 V, < 100 kHz No spec. 60 V No spec.
1000 V 50 V, < 100 kHz No spec. 120 V No spec
