	Basic 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 one digital change.
