Problems solved by technology

[0003] Existing electric energy meter enterprises only perform data communication on the RS485 port of the electric energy meter in the intelligent testing equipment. When the load is too much, there will be abnormal communication problems in the field operation, and it cannot be said that the fault is well controlled in the factory
In addition, some watt-hour meter companies use artificial pairings to measure the RS485 port voltage during the production stage, which is inefficient and cannot meet the requirements of assembly line operations.
