摘要
现有万用表校验仪具有操作复杂、显示单一、高压检测电流过大、电压/电流错误档位切换缺少判断和保护功能以及频繁开关动作导致的开关配合失调等不足,本文以单片机作为微控制器核心配合外围人机交互输入模块开发了万用表校验检测平台,用于万用表实训各种数据的校验,并显示校验结果。万用表校验平台解决上述问题,提高万用表校验的效率和该实训课程的教学效果。
The existing multimeter calibrator has the deficiencies of complicated operation,single display,excessive current in high-voltage detection,lack of judgment and protection function in the switching of the wrong voltage/current position,and the switch mismatch caused by frequent switching actions.In this paper,a multimeter calibration platform is developed with microcontroller as the core and other circuits,which is used to verify various data of the multimeter for training and display the calibration results.The multimeter calibration platform solves the above-mentioned problems and improves the efficiency of multimeter calibration and the teaching effectiveness of this hands-on course.
