DEVELOPMENT OF RESISTANCE PARAMETER INSTRUMENT FOR ELECTRIC BLASTING NETWORK
Ji Zhang · Engineering Blasting · 2004
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.
