摘　　要：非自动衡器在生产生活中十分常见,其测量准确性至关重要,与人们的利益密切相关。因此,对非自动衡器的精度要求极为严格。但是,非自动衡器在使用过程中,容易受到各种因素的影响而产生误差,影响测量结果的准确性和客观性。对此,文章以电子计价秤为例,深入分析非自动衡器的测量误差不确定度。探究电子计价秤测量误差不确定度的来源,得到电子计价秤的最大允许误差改变载荷和最大秤量示值误差的测量不确定度,以期为检定机构开展检定工作提供参考。Non-automatic weighing apparatus is very common in production and life,and its measurement accuracy is very important and closely related to people’s interests.Therefore,the precision requirements of non-automatic weighing instruments are extremely strict.However,the non-automatic weighing instrument is easily affected by various factors in the process of use,resulting in errors,which affect the accuracy and objectivity of the measurement results.In this regard,the paper takes electronic valuation scale as an example to analyze the uncertainty of measurement error of non-automatic weighing device.The source of the uncertainty of the measurement error of the electronic valuation scale is explored,and the uncertainty of the maximum allowable error change load and the maximum measurement error of the scale is obtained,in order to provide reference for verification institutions to carry out verification work.
