Anyone know much about electronics?
I have an NTC probe that reads 9K @ 0C and I want to add a mechanical offset as the controller does not have this functionality.
If I throw a 32K resistance in parallel I should get my +5C offset at 0C which is perfect.
BUT... I'm feeling a little greedy and I'd like to trim it a little each way, and I reckon between 25K and 50K would be a perfect amount. If I throw a 50K potentiometer in there, it's variable between 0 and 50,000 which is not ideal. Is there such a thing as a potentiometer or similar that provides between 25K and 50K resistance?
