摘　　要：从电路原理出发,给出了电表改装实验中电路参数的计算方法和电路设计的技术要求;并通过对电路中相关物理量两种不同方式的测试,给出了在电表改装实验中正确选择元件、合理配置参数和减小测量误差的具体做法.结果表明,要提高测量准确度,应采用改装表与标准表同时接入电路测量的方式.the paper advances the calculation method of circuit parameter in the experiment of electricity meter refits and the technique requirement of circuit design according to circuit principle, gives a comparative analysis on the test results drawn by the two different related ways of physics measures, and offers a specific way of collocating reasonable circuit parameter to let up the diagraph error margin. The result shows that accurateness of measurement should adopt refitting form and standard form at the same time, connecting into electric circuit measurement.
