This unit is used for the automatic verification operation of the digital multimeter. The computer is used as the core to complete the verification of the digital multimeter, and the digital image processing technology is used for the digital universal representation number reading. The verification data and verification results in the multimeter verification process are stored in the computer. The device realizes the automatic operation of the digital multimeter from instrument plug-in, range adjustment, reading recognition, data storage, data processing, and result determination. The utility model relates to a digital multimeter verification device, belonging to the field of automatic verification of power meters.
