一、前言日本电气计器检定所东京试验所现用超高电阻电桥和 Guildline 公司制造的9520型太欧表建立超高电阻标准并开展检定工作。由于这些仪器所测的阻值极高,分布电容及测量仪器本身的工作原理使得时间常数很大,数据稳定性不良,所需测量时间也较长。要想提高测量效率和检查精确度,就须实现测量的自动化,为 First, the foreword Japan’s Electrocardiograph test Tokyo Testing Institute is currently using ultra-high resistance bridge and Guildline manufactured 9520-type ultra-ohmmeter table to establish ultra-high resistance standards and carry out verification work. Due to the extremely high resistance measured by these instruments, the working principle of the distributed capacitance and the measuring instrument itself makes the time constant very large, the data stability poor, and the measurement time required. To improve measurement efficiency and inspection accuracy, it is necessary to automate the measurement
