摘要（英）：

The utility model provides a portable electric energy metering terminal calibration instrument. The instrument comprises a standard power source, a standard electric energy meter, a communication protocol detection module, a pulse comparing module, and an electric energy error calculating module. The standard power source is connected with the standard electric energy meter and a detected electric energy metering terminal. The detected electric energy metering terminal is connected with the communication protocol detection module. The pulse comparing module is connected with the standard electric energy meter and the detected electric energy metering terminal. The electric energy error calculating module is connected with the pulse comparing module. The instrument which can achieve on-site detection of errors of the electric energy metering terminal further provides communication protocol on-site detection. Operations of users are facilitated. Interoperability is further achieved.
