摘要
分析了用半偏法测量电流表内阻时系统误差产生的原因,提出了三种具体的改进方法,并对三种改进方法的优点及精确度进行了详细的讨论。
This article discusses the possible reasons of the system errors,which could happen while using halfbias method to measure the inner-resistance of current meter,and brings forward three detailed improvements.Further discussions about the advantages and precision of the improvements are also provided.
