Automatic calibration equipment of electric energy meter error

The utility model provides an automatic calibration equipment of electric energy meter error, an error is measured for being directed at receive the examination electric energy meter, the device includes the load module, microprocessor gathers measured module and installs the test terminal of testing software, the load module is connected to and receives the examination electric energy meter, microprocessor gathers measured module and is connected to the test terminal, a serial communication port, still including being used for gathering the optic fibre that receives the smooth pulse signal of examination electric energy meter with the transmission, a photoelectric conversion module for inciting somebody to action light pulse signal converts electric pulse signal into, a signal line for transmitting electric pulse signal, the one end and the input of photoelectric conversion module of optic fibre are connected, the other end of optic fibre with contacted by the smooth pulse signal pilot lamp of examination electric energy meter, measured module is gathered to microprocessor to the output passing signal line connection of photoelectric conversion module. The anti -electromagnetic interference of optic fibre can the reinforce, can keep apart the electromagnetic disturbance who exerts in receiving the examination electric energy meter, has guaranteed the electromagnetic compatibility of electric energy meter automatic calibration equipment of electric energy meter error's in experimental normal work.
