Thanks Mike, very relevant, I cleaned up the beam finder switch and the

an improvment over 2.5 and 4 squares (1:1.6). Beam finder switches clearly
don't get used much!


Glad to hear that this helped you.

Exercise all those switches vigorously. My 485 took quite some time to become fully functional. I cleaned and used DEOXIT on the thing about 3 or 4 different times before the trace came fully back as it should be. Make sure to use a cleaner that does not leave residue or attract dust.

There are a lot of these switches on TEK scopes and they all suffer from the same malady. Clean everyone that you can find on your 2215.

I find dirty switches and contacts are the number one cause of scope "failures".

Good Luck with your scope.
