start
Under the conditions of reference voltage, reference frequency, and power factor of 1, the meter can start and continuously record when the load current is 0.4% Ib.
Stealth
When a reference voltage of 115% is applied, the circuit is disconnected and no more than one electrical energy pulse is output.
