由于操作者的存在而引起周围环境参数的变化,可给精密称量结果带来不良影响。因此,应用技术设备在3～4m 处远距离操纵高精度天平和获得测量信息。但这种技术设备同样也可能成为误差源。例如在日本千代(chyo)天平公司的精密天平的计量鉴定期间进行了研究,查明了读数系统任何元件对最佳空间位置的偏离都将导致一种器具误差分量。由文献[3]可知,在评定测量准确度时最困难的
Due to the existence of the operator caused by changes in ambient parameters, can bring adverse effects on precision weighing results. Therefore, the application of technical equipment at 3 ~ 4m remote control high-precision balance and access to measurement information. However, this technical equipment may also be a source of error. A study, for example, was conducted during the metrological qualification of a precision balance at Chyo of Japan, identifying that deviations of any element of the reading system from the optimum spatial position will result in an instrumental error component. From the literature [3] shows that in the measurement of the most accurate measurement accuracy
