摘  要:运用贝塞尔公式进行 A 类不确定度评定时,通常包含了重复性和分辨力引入的不确定度分量。文章以 FLUKE 5700 为标准,将 Agilent 34401 作为被校准仪表,对其进行不确定度评定,并讲述了重复性引入的不确定度与分辨力引入的不确定度之间的关系。以此为基础,进一步讨论了重复性引入不确定度的读数方法,以及多功能、多量程数字式仪表如何确定分辨力引入的不确定度。

Abstract: When the Bessel formula is used to evaluate the type A uncertainty, the uncertainty components introduced by the repeatability and resolution are usually included. This paper takes FLUKE 5700 as the standard, and uses the Agilent 34401 as the calibrated instrument which is evaluated its uncertainty, and describes the relationship between the uncertainty introduced by repeatability and the uncertainty introduced by resolution. Based on this, the numerical reading method of the uncertainty introduced by repeatability and how the multi-function or multi-range digital meters determine the uncertainty introduced by resolution are further discussed.

Keywords: repeatability; resolution; digital instrument; type A uncertainty
