Description

【Technical field】 [0001] The invention relates to a test device for debugging the daily time error of an electric energy meter, and belongs to the technical field of daily time test devices. 【Background technique】 [0002] The daily timing error of the electric energy meter is the difference between the electric energy meter clock and the standard time after one day of operation. The internal clock of an electric energy meter with a large daily time error value will have a larger and larger difference with the standard time. When the difference between the electric energy meter clock and the standard time is large, the accuracy of the measurement data of the electric energy meter will be affected. Therefore, the electric energy meter is shipped from the factory. , It is necessary to detect the daily timing error of the electric energy meter. The State Grid and China Southern Power Grid have very strict requirements on the daily timing error of the electric energy meter. Only...
