摘要
介绍一种基于 AD7705和 ATMega8的新型接地电阻测试装置，分析该接地电阻测 试装置的设计原理，详细地说明系统的软硬件设计方法，并创造性地提出利用恒流源来构成系统 的采样电路。
A new-type grounding resistance measuring system based on IC AD7705 and iC Mega$ is introduced, and its working principle is illustrated in detail. Further the design method of hardware and software is given. Meanwhile, the constant-currant power which is used to the sample system is also creatively proposed.
