Suntan Reliability of a Trimming Potentiometer
The reliability of a potentiometer depends on its ability to continue performing its intended function. Since the primary function is to provide a continuous and proportional voltage output, the primary reliability considerations are continuity and proportional voltage output. A failure in continuity is always catastrophic, as the device is no longer acting as a potentiometer.
The primary constituents of continuity are:
- Wiper contact to conductive surface
- Continuous conductive surface
- Wiper (output) and excitation terminal continuity
