一、概述1测量依据JJG539《数字指示秤检定规程》2测量环境温度:16℃;相对湿度:60%3测量标准:M1、M12级砝码4被测对象:60t电子汽车衡5测量过程:用砝码直接加载、卸载的方式进行检测,测量示值与标准砝码之即为60吨电子汽车衡的示值误差。6评定结果的使用:符合上述条件的测量结果,可直接使用本不确定度的评定结果。二、数学模型Δm=M-m(1)式中:Δm——被测数字电子秤示值误差;M——被套测数字电子秤的示值;m——标准砝码质量值。
I. Overview 1 Measurement According to JJG539 “Digital Indicating Scale Verification Regulation” 2 Measurement environment temperature: 16 ℃; Relative humidity: 60% 3 Measurement standards: M1, M12 weight 4 The measured object: 60t electronic truck scale 5 Measurement process: Directly loaded with the weight, unloading way to detect, measure the value and the standard weight that is 60 tons of electronic truck scale indication error. 6 Use of the evaluation result: The measurement result meeting the above conditions can be directly used to evaluate the result of this uncertainty. Second, the mathematical model Δm = M-m (1) Where: Δm - measured digital electronic scale indication error; M - was measured digital electronic scale indication; m - standard weight quality value.
