Design Strategy of Automatic Calibration System for Handheld Digital Multimeter
Abstract: The traditional calibration method of handheld digital multimeter has the characteristics of complex operation process, low efficiency and large error. To optimize this situation, a corresponding calibration system needs to be developed. The design strategy of the automatic calibration system of the handheld digital multimeter is analyzed. The system can automatically switch the gear of the multimeter, and can also compare the signals at the same time, and realize the simultaneous calibration of several multimeters. This is very conducive to improving the measurement industry. The work quality and efficiency have certain engineering practical value.
