所谓非自动秤,是指在称量过程中必须用人操作的秤。正确地判定非自动秤的准确度等级,关系到秤的允许误差和有效使用范围,有助于我们在计量过程中正确地选用衡器,获得相应准确度的计量结果。 按照国家计量检定规程规定,非自动秤的准确度分为三个等级,即2级(高准确度级)、3级(中 The so-called non-automatic scale, refers to the weighing process must be operated by the scale. Accurately determine the level of non-automatic scale accuracy, relates to the allowable error scale and the effective use of range, help us in the process of measuring the right selection of scales, to obtain the appropriate accuracy of the measurement results. In accordance with the provisions of the national metrological verification procedures, non-automatic scale accuracy is divided into three levels, that is, 2 (high accuracy level), 3 (medium
