适用范围：1.1 This standard applies to dc potentiometers assembled from resistors and switches and operating entirely on direct current, having accuracyclasses of 0.000 5......0.l ( 5 ppm......1000 ppm ). It applies also toauxiliary equipment which is a built-in part of the potentiometer.1.2 This standard does not apply to potentiometers which are set auto-matically or semi-automatically nor to those which also employ graduations on the null detector to obtain a part of the indicated value, nor to external auxiliary equipment used with the potentiometer.
