Good Morning,

I am putting together a winkey keyer kit (I know it is not true homebrew,
but I am just a lowly English teacher). Anyways, I have a variable pot with
three poles and need to know which one is ground. How can I find that out
with a multimeter?

Thanks and 73

Do you mean you want to know which tag is attached to the wiper? If that
is what you mean, just measure the resistance between any pair of
terminals, the pair for which the resistance does not change regardless of
position of the pot, neither pin will be the pin you want.

Its usually the centre one.
