摘　　要：为适应仪器仪表国际标准要求及满足仪器仪表虚拟化发展方向,研制了仪器仪表电气安全性测试仪,分析了其绝缘电阻测试系统的原理与设计,该测试系统由单片机系统、测试回路和计算机系统组成,在0～2 000 MΩ的测量范围内,该系统测量误差＜1%(1σ),精度高,符合IEC61010标准要求;同时结合了PC机和单片机系统作为测控核心,使系统操作方便,也符合仪器虚拟化发展方向.A security tester for apparatus and instrument is designed and manufactured in order to meet the international standards of instrument and the demand of instrument development. The theory and design of isolation-resistance test system in electric security tester are introduced. The testing system, which is composed of computer system, testing circuit and MCU,meets the standard of IEC61010. The measured error is less than one per（1σ） between 0 and 2 000 MΩ. The system is centered with computer and MCU ,thus facilitating its manipulation and answering the demand of instrument development.
