We have a similar potentiometer to the one pictured here which gives no resistance readings between any of the three legs; is there any way of obtaining reference readings without altering the adjustment?


My thoughts were to give it a good spray with solvent switch-cleaner with the meter still connected and on

If you are getting no reading at all either there is something wrong with your meter or the way you are using it. What reading do you get shorting test leads? Check range setting
Very brief reply now, more later. Glad messages are working. Cut track means pot acts only as a variable resistor (like any other resistor ie 2 connections) but can be adjusted from 0 to specified maximum. 3rd leg irrelevant.
When you say 'no resistance reading', what does the ohm meter say? 0 (or say 0.3) means short circuit, eg copper track or solder bridge. anything above say 10M means open circuit, same as connected to nothing. A pot in circuit is almost bound to have a measurable resistance between each pair of legs (except for the 3rd leg of a cut track pot, which might be connected to anything or nothing.

Confusion Between Us
There had been some confusion between us regarding your resistance readings where you have noted a 0; when I see this, I read it as no reading at all, whereas you mean it to be continuity.
As an illustration; when I connect my two meter probes together I am looking for a reading of continuity, yet I still get a small reading 0.1 or 0.2, I have accepted this as normal to be okay.
