Field calibration metering error system and method

The invention relates to a field calibration metering error system and method. The problems in the prior art that electric energy meters need to be frequently assembled and disassembled for error detection, time and strength are wasted, there are potential safety hazards, and the pertinence and the efficiency are low are solved. The system includes an electric meter side and a server side, the electric meter side includes an electric energy meter and a metering box connected to the electric energy meter, and the metering box includes a sampling unit, a calculating unit and a communication unit. The sampling unit collects current voltage information, and the calculating unit calculates an actual energy value within a set pulse number according to a received request, compares the actual energy value with a conventional energy value in the pulse number, calculates an error value and sends the error value to the server side. According to the field calibration metering error system and method, the error detection
