Potentiometer testing systems and methods

Abstract:

A system includes analysis circuitry. The analysis circuitry is configured to determine a first electrical resistance between a first terminal of a potentiometer and a second terminal of the potentiometer. The analysis circuitry is additionally configured to determine a second electrical resistance between the first terminal and a wiper terminal of the potentiometer. The analysis circuitry is additionally configured to determine a third electrical resistance between the second terminal and the wiper terminal. The analysis circuitry is additionally configured to determine a wiper resistance of the potentiometer based on the first electrical resistance, the second electrical resistance, and the third electrical resistance. The system additionally includes an output interface coupled to the analysis circuitry and configured to generate an output indicative of the wiper resistance.
