[QUOTE="Mr Magoo, post: 332937, member: 3008"] That's what I had heard. Contrary to the owner of a well known lapidary supplier, potentiometer [i]are not[/i] reliable. And the example he gave, that is why the automotive industry uses them, is a bad example. They were notorious for failing - causing all sorts of problems. In fact they went to using two so one could check the other but now the likely hood of a problem occurring has doubled . Which is why the auto industry gave up and started using hall effects. Either way, I wouldn't like to swear on the capabilities of a pot for reliable accuracy. [/QUOTE]
