摘　　要：本文以数字多用表校准装置为例,对其测得值的典型值进行不确定度分析,并针对实际工作中数字多用表校准后,整个测量范围内的测得值不确定度存在计算时间长、易出错、效率低等问题,提出预评估应用实际工作的思考。This paper takes the digital multimeter calibration device as an example to analyze the uncertainty of the typical measured value.In view of the problems of long calculation time,easy error and low efficiency of the measured value uncertainty in the w hole measuring range after the calibration of the digital mulimeter in practical work,the paper puts forward the thinking of preevaluation application.
