2）Starting

 When the rated voltage, rated frequency and power factor is 1.0, the loaded current is 0.004Ib(class1)、0.005Ib(class2), the meter shall starts and measures energy continuously.

3） Creeping

 When the voltage circuit is loaded with a voltage 1.15 times of the rated voltage and there is no current in the current circuit, the meter is supposed not to output more than one pulse.
