In order to meet the increasing demand of distributed DC power supply, DC load and DC power verification, a multi-epitope DC electric energy meter automatic verification device is developed. The verification principle, hardware design and software design are given, and the repeatability test, stability test and uncertainty evaluation of the calibration device are also carried out. The test results show that the calibration device has stable measurement value and high accuracy, and the calibration results meet the requirements of the relevant national verification regulations. It has wide application prospects.
