[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, please note that in the case of low voltage (no more than 500 volts) and small current (tens of amperes), the electric energy meter can be directly connected to the circuit for measurement. In the case of high voltage or high current, the electric energy meter cannot be directly connected to the circuit and must be used in conjunction with a voltage transformer or a current transformer.

[0003] During the use of the electric meter, since the electric meter is mostly exposed outdoors, dust will adhere to the outer side due to environmental influences, which will cover the display area of ​​the electric meter. When the staff observes the meter data, they need to wipe the dust off the display area of ​​the meter before they can observe and record the data. At the same time, the staff's fingers will also be contaminated with dust, reducing the convenience of using the meter.
