摘要
用 HX-20微型计算机于电阻器件质量参数的检测,必须解决 A/D 转换问题.本系统用7151计算万用表实现了 A/D 转换,它与 HX-20一样运行 BASIC 语言.HX-20对7151进行初始化并控制测试电路,实现检测自动化,并使系统获得很高的测试精度.
It is necessary to solve the problem of A/D conversion by means of HX-20 microcomputer for testing the qualitative parameters of the carburized procelain resistor.In this system,we use 7151 computing multimeter to realize A/D conversion.Moreover,HX-20 microcomputer runs BASIC language as the multimet- er does,so it can initiale the multimeter and controls its measuring circuit to realize automatic detection,thus the system achieves a high measuring precision.
