摘要
本文以电子秤为例介绍了数字指示秤测量结果不确定度的来源和评定方法,并通过实例计算数字指示秤的标准不确定度,合成不确定度以及扩展不确定度;并且列举了不同分度值和载荷点的测量不确定度。
Taking electronic scale as an example,this paper introduces the source and evaluation method of uncertainty in measurement results of digital indicating scale.We calculate the standard uncertainty,combined uncertainty and expanded uncertainty of digital indicator scale through examples,and list the measurement uncertainty of different graduation values and load points.
