[0002] With the rapid development of my country's economy, the demand for electricity from all sectors is increasing, and the uneven distribution of electricity consumption at different times is becoming increasingly serious. To alleviate the increasingly acute contradiction between electricity supply and demand, regulate the load curve, and improve the uneven distribution of electricity consumption, power departments in some provinces and cities have begun to gradually introduce multi-rate electricity meters, which charge users based on their time of day. The widespread use of electricity meters has also made meter inspection particularly important, and simple on-site electricity meter verification instruments are more convenient for people at different levels to use.
