摘　　要：针对数字多用表种类繁多、操作复杂、校准效率低下等问题,开发数字多用表自动校准系统,该系统能够自动调用Excel表格中设置好的校准点,控制校准源输出信号、读取数字多用表读数并自动计算误差判定,实现了数字多用表的自动化校准并能保证整个系统的稳定性。Aiming at the problems of various types,complex operation and low calibration efficiency of digital multimeter,an automatic calibration system of digital multimeter is developed. The system can automatically call the calibration points set in Excel table,control the output signal of calibration source,read the reading of digital multimeter and automatically calculate the error judgement. It realizes the automatic calibration of digital multimeter and ensures the stability of the whole system qualitative.
