25kg砝码示值误差检测数据

砝码是质量量值传递的标准量具。对砝码示值误差检定数据的分析可以用来判断全县砝码的整体计量准确性情况，为使用单位进行计量偏差监控提供数据支持。砝码的示值误差检定是由被测砝码与标准砝码依次使用电子天平进行称量，以ABA的顺序依次进行，A1、A2为标准砝码的称量示值，单位为g；B为被测砝码的称量示值，单位为g；E0为标准砝码修正值，单位为mg；根据公示E =E0+1000*((A1+A2)/2-B),计算出示值误差E，单位为mg；根据砝码标称值对应等级砝码的允许误差规定。示值误差E在允许误差范围之内，判断其示值误差合格。

Weights are standard measuring instruments for mass quantity value transfer. Analysis of the indication error verification data of weights can be used to assess the overall metrological accuracy of all weights within the county, and provide data support for metrological deviation monitoring for the employing units.
The indication error verification of weights is conducted by sequentially weighing the test weight and standard weights with an electronic balance in the ABA sequence, where A1 and A2 are the weighing indications of the standard weights in the first and third measurements respectively, with the unit of grams; B is the weighing indication of the test weight, with the unit of grams; E0 is the correction value of the standard weights, with the unit of milligrams.
The indication error E is calculated using the formula E = E0 + 1000*((A1+A2)/2 - B), with the unit of milligrams.
According to the allowable error specifications for weights of the grade corresponding to the nominal value of the weight, if the indication error E falls within the allowable error range, the indication error is deemed qualified.
