多分度秤测量结果的不确定度评定

【摘要】多分度秤是只有一个称量范围，且该称量范围又由不同分度值分成几个局部称量范围的一种秤，在对其进行测量结果不确定度评定过程中需要确定检定载荷点和分度值，测量结果的不确定度需满足特定关系时，才可进行相应的符合性评定。

Abstract： A multi graduation scale is a type of scale that has only one weighing range and is divided into several local weighing ranges by different graduation values. In the process of evaluating the uncertainty of measurement results， it is necessary to determine the calibration load point and graduation value. When the uncertainty of measurement results meets a specific relationship， corresponding conformity evaluation can be conducted.

Key words： multi graduation scale； uncertainty assessment； load point； graduation value
