This research was motivated by technical-economic challenges imposed by mass metrology, specifically, in matters concerning calibration methods of non-automatic type weighing instruments (: digital scales). In order to contextualize the problem detected, in the industry there are different processes of mass measurement that are controlled by digital scales, such as: mass of liquids, chemicals, food, body mass of a person. In these processes, the scale is used in the following four conditions for mass measurement: (i) ascending and descending load, returned to zero; (ii) ascending and descending load, without the need to return to zero; (iii) only with ascending load and (iv) only with descending load. In this context and, maintaining the principles for the calibration of a measurement instrument in which it must be carried out under the same operating conditions as the instrument, metrology laboratories must knowing the metrological reliability (: errors and uncertainties) for each situation. This is exactly the main motivation for the development of the research. Thus, the experimental data obtained in a research laboratory under controlled environmental conditions allowed obtaining a minimum expanded uncertainty associated with the mass measurement of 0.0012 kg (=2; confidence level: 95%).
这项研究的动机源于质量计量所带来的技术经济挑战，具体而言，涉及非自动式称重仪器（即数字秤）的校准方法相关问题。为了将所发现的问题置于具体情境中，在工业领域存在不同的质量测量过程，这些过程由数字秤控制，例如：液体质量、化学品质量、食品质量、人体体重。在这些过程中，秤在以下四种质量测量条件下使用：（i）加载和卸载过程中，返回零位；（ii）加载和卸载过程中，无需返回零位；（iii）仅加载；（iv）仅卸载。在此背景下，并且秉持测量仪器校准的原则，即校准必须在与仪器相同的操作条件下进行，计量实验室必须了解每种情况下的计量可靠性（即误差和不确定度）。这正是开展此项研究的主要动机。因此，在受控环境条件下的研究实验室中获得的实验数据，使得能够获得与质量测量相关的最小扩展不确定度为0.0012千克（=2；置信水平：95%）。
