替代法测表头内阻的误差分析

The Error Analysis of the Measurement of Amperemeter Resistance with the Substitute Method

讨论了用替代法测微安表内阻时产生误差的原因和消除误差的方法，提出了选择电路参数时应注意的事项．

In this article we discuss the error origin and the amendment in the process of amperemcter resistance measurement with the substitute method and we also point out the matters needing attention in the selecting of the circuit parameter.
