Design of Automatic Calibration System for Digital Multimeter
Abstract: Digital multimeter is widely used in electrical measurement due to its many functions and excellent performance. In order to ensure the accuracy and precision of electrical parameter measurement, regular verification work must be carried out on the digital multimeter. Traditional verification methods mostly use manual verification methods, but due to the human factors of the verification personnel, there are disadvantages such as low efficiency, high cost, and complicated verification process. For this reason, the digital multimeter automatic verification system is developed by comprehensively using computer technology, image processing and recognition technology and communication technology, and the uncertainty analysis of the verification results is carried out.
