Description

technical field [0001] The invention relates to the technical field of electric energy meter calibration, in particular to an electric energy meter error correction method with high meter calibration efficiency and high meter calibration accuracy. Background technique [0002] At present, the calibration method of the high-precision electric energy meter of the electric meter manufacturer generally adopts the error calibration method, that is, the error of the meter calibration station is read after the electric energy meter emits a pulse, and the compensation amount is calculated and then written into the electric energy meter. This calibration method has the disadvantages of long calibration time and low production efficiency. [0003] For energy meters with low precision requirements, power calibration is usually used, that is, reading the power of the energy meter and the power of the meter calibration station, calculating the compensation amount and writing it into the ...
