摘　　要：基于GPIB的数字万用表自动测试系统由计算机、万用表、交/直流标准信号源、打印机、GPIB接口等组成。系统软件以VB 6.0伟开发平台,分自动校准/测试/检定功能模块。微机同时控制信号源和万用表完成自动校准,再人机对话选择校准检验判断是否再校。用户输入被测表型号、GPIB地址,选择测量功能与量程及次数等,执行自动测量。自动检定采用标准源法,按需选择检定点,实时处理其数据并判定结果。Automatic testing system of digital multimeter based on GPIB consists of computer, multimeter, alternating/direct current standard signal sources, printer, interfaces of GPIB and so on. System software developed with VB 6.0 can be divided into three function modules of automatic regulating\ testing \ evaluating. The computer controls both signal sources and the multimeter simultaneously to accomplish automatic regulating, and man-to-machine dialogue selective regulating determines whether it is necessary to regulate again. The user inputted the type of the tested multimeter and GPIB address, and selected measurement function, range, times etc, and automatic measurement was performed. The standard sources were employed in automatic evaluating, the evaluated point was selected according to its requirements, handled the data in real time and judged the result.
