质量比较仪校准结果的不确定度评定及CMC表示

The calibration results of mass comparator uncertainty and CMC

质量比较仪是砝码量值传递系统最重要的配套设备。是基于ABA或ABBA循环方式测量质量差值,以全量程或电子秤量范围加配衡的秤量方式的高分辨率电子衡量设备。本文根据质量比较仪的工作原理和计量特征,分析质量比较仪校准结果不确定度的来源、评定方法和最佳校准能力的表示,为开展质量比较仪校准提供技术帮助。

A quality comparator is the most important system of weight value transmission equipment, and ABA or ABBA cycle mode based on the high resolution electronic weighing equipment, with high resolution electronic weighing equipment weighing way full range or electronic weighing range plus tarred. According to the working principle and measurement characteristics of mass comparator, this paper analysis of mass comparator calibration results the sources of uncertainty, evaluation methods and the optimal calibration capability, to provide technical assistance to carry out quality eomparator calibration.
