    We have a temperature probe that is used in a water heater that comprises three thermistors. In production we can find one or more thermistors can short circuit (ie the measured resistance is low) or, more commonly, break to an open circuit (ie the measured resistance is too high). It takes time to replace the thermistor, so we would like a small tester made that can verify the component does n...
