Auto range
switching | Range up:When the measuredvalue exceeds
110% of the rated value.or when the
peak value exceeds 350%of the peak value.
Range down:When the measured value
becomes less than30% of the rated value. |
Measurement
mode
Switching | The mode can be setfor each element
and also for each voltage and current measurement circuit. |
