| Abstract: | In order to solve the problem that the calibration of widely used handheld digital multimeters still relies on manual work, according to JJF 1587-2016 "Calibration Specification for Digital Multimeter", an automatic calibration device for hand?held digital multimeter is designed. The calibration device realizes the position control, function, range switching and motion control of the hand?held digital multimeter through the electromechanical system. The data reading of hand?held digital multimeter is realized through the visual recognition system. Combined with calibration software, 8?station continuous automatic calibration is realized. It is verified through test that the device improves the calibration efficiency of handheld digital multimeter and can meet the calibration requirements of handheld digital multimeter. |
