摘　　要：本文力求用完整的信息评定与表示,通过对电参数测量仪功率示值误差测量结果不确定度的分析,解决电参数测量仪其他参量的示值误差测量结果不确定度的评定。目前在分析被测表的示值引起的标准不确定度时,一般采用A类评定方法,但考虑到被测电参数测量仪示值本身在变,且在重复性测量过程中,它的示值改变在不稳定变化范围内,因此被测表的示值引起的标准不确定度来源于被测电参数测量仪的示值变化和读数分辨力,故本文采用B类方法进行评定。评定结果具有一定的普遍性和实用性。This paper aims to seek a solution of the evaluation of measurement uncertainty about indication error of other parameters on the basis of the analysis of the assessment of measuring uncertainty about power indication error for an electric parameter meter.At present,type'A'evaluation method of uncertainty is often employed in analyzing the standard uncertainty caused by the indication for an electric parameter meter.However,considering its changeable indication and the fact that the indication changes within the range of unsteady changes during the repeated measuring,the standard uncertainty caused by the indication for an electric parameter meter stems from the indication changes and the ability to distinguish reading.Therefore,this paper employs type'B'evaluation method of uncertainty And the evaluation result is universal and practical.
