摘要
通过研究电位差计的使用原理,介绍了用电位差计测量电源电动势及微安表内阻的方法,并结合不确定度理论对数据进行了分析和处理,以保证设计和测量精度。
Through researching potentiometer application principle, the method of measuring electromotive force and inner-resistance of micro-ampere-meter in use of potentiometer was introduced. In combination of uncertainty theory, data analysing and processing were all done so as to ensure both the design and the accuracy measured.
