This paper introduces an intelligent testing system for overall measurement of the rotational noise of potentiometers. In terms of IEC standard, the testing system can be used for measurement of the rotational noise and the contact resistance variation and the output smoothness of potentiometers. The testing system is particularly suitable for analyzing and researching the patterns of the rotational noise of potentiometers because it can stroe and restore patterns of the rotational noise. It can be formed easily and also used as a quality checking apparatus of potentiometers in factories.
