摘要
标准电阻生产后 ,需要对其进行检定。人工检定的方法操作烦琐且易引入误差。我们采用HP 34 970A(数据采集 /开关单元 ) ,经HPIB总线与PC主机相连 ,组成自动测试虚拟仪器 (软件平台采用HPVEE ,虚拟仪器的最大特点是用户可以自行定义仪器的功能和界面 )。测试完毕 ,通过DDE(DynamicDataExchange)自动生成检定报告书。这样 ,不仅简化了测量过程 ,测量精度也得到了提高。本文详细讨论了软、硬件的主要技术及设计思想。
It is necessary to check the standard resistances after they are produced. Manual method is prolix and usually produces error easily. Here, Virtual Instruments is used with the connection of computer HP 34970A to HPIB bus. HP VEE is used as the software platform of VI. After testing, report is given by DDE. Simplified measurement process with high precision is presented. The designing ideas and main techniques are also given in detail in this paper.
