Metering function

Start current: under rated voltage, when the load current value of the meter doesn’t exceed 1% of the max. current, the meter
starts.
Shunt running current: when there is no current in the current circuit of the meter, and 85%-125%of the rated voltage is applied
on the voltage circuit, the calculator shall not have more than
