摘要(Abstract)：

电爆网路电阻参数测量的安全性、准确性至关重要。考虑到普通指针式仪表的缺陷,基于大规模集成电路31/2位双积分式A/D转换器ICL7106制做了一种电爆网路电阻参数检测仪。文中介绍了该仪表的主要技术指标、各组成部分的测量原理,同时介绍了检测仪电路及其调整。试验测试表明,该检测仪测量结果准确、安全可靠。
Security and veracity is very important in measuring the resistance parameter of electric blasting network. In consideration of the shortages of common pointer-type meters, a kind of resistance parameter instrument for electric blasting network was developed based on the large-scale integrate circuit 312 digit twin integral style A/D converter ICL7106. In this paper, technical specifications and component function of the instrument are introduced and the detecting circuit and its adjustment are presented. The trial tests show that this instrument is veracious in measuring results and safe in use.
