电子计价秤计量比对及结果分析

Measurement comparison and result analysis of electronic price scales

为全面了解上海市计量技术机构的非自动衡器检定装置的技术水平,确保电子计价秤量值传递的准确可靠,上海市计量测试技术研究院作为主导实验室,对准确度等级为Ⅲ级、最大秤量为15 kg的电子计价秤组织实施了计量比对,比对参数为称量示值。本文从比对技术依据、传递标准、参考值、比对结果等方面做了详细的阐述,同时对比对过程中出现的问题进行了分析,并提出了建议。

To comprehensively understand the technical level of non-automatic weighing apparatus in metrological institutions in Shanghai and ensure the accuracy and reliable transmission of values for electronic price scales,Shanghai Institute of Measurement And Testing Technology,as the pilot laboratory,organized a measurement comparison for electronic price scales with an accuracy class of 3 and a maximum weighing capacity of 15 kg.The comparison parameter used was the weighing indication.This article provides a detailed explanation from various aspects such as the technical basis for the comparison,reference standards,reference values,and comparison results.It also analyzes the issues encountered during the comparison process and provides suggestions.
