[0002] An electric energy meter is an instrument used to measure electric energy. It is also called an electric meter, a fire meter, or a kilowatt-hour meter. It refers to an instrument that measures various electrical quantities. When using an electric energy meter, you should pay attention to the following: in the case of low voltage (not exceeding 500 volts) and small current (tens of amperes), the electric energy meter can be directly connected to the circuit for measurement.
