What is BS EN 60523 - Direct-current potentiometers about?
BS EN 60523 is an international standard that discusses the uses of direct-current potentiometers .
BS EN 60523 applies to DC potentiometers that have accuracy classes of 0.0001 ... 0.1 [1 ppm ... 1,000 ppm (parts per million)] [1 × 10–6 ... 1 × 10–3(scientific notation)].
BS EN 60523 also applies to auxiliary equipment which is a built-in part of the potentiometer.
Note: BS EN 60523 does not apply to potentiometers in which the null balance is obtained automatically, to those which employ graduations on a balanced detector to obtain a part ...
