电位差计的检定方法有许多种,此处所选用的方法是根据被校仪器和标准仪器的特点而定。因为电位差计本身是一种比率仪器,所以其检定可以与外部标准无关。在该方法中使用的小型专用装置可以使大多数实验室完成自己的检定。Brooks 叙述了一种检定电位差计的方法,该方法主要依靠一台已经检定好的万能 There are many ways to calibrate the potentiometer. The method chosen here is based on the characteristics of the instrument being calibrated and the standard instrument. Because the potentiometer itself is a ratio instrument, its verification can be independent of external standards. The small dedicated device used in this method allows most laboratories to perform their own tests. Brooks describes a method of verifying a potentiometer that relies primarily on a well-calibrated omnipotence
