6. a kind of detection method for digitalized electrical energy meter, which is characterized in that the detection method includes:
Power output order is issued using error testing main control module；
Using digitlization power source according to the power output order output quantization digital quantity；
The quantization digital quantity is transferred to by digital standards electric energy meter and tested digitalized electrical energy meter using communication module and is counted
It calculates, respectively obtains the first accumulation electric flux and the second accumulation electric flux；
The first accumulation electric flux and the second accumulation electric flux are compared using the error testing main control module
The error amount of the tested digitalized electrical energy meter is obtained afterwards.
