Ok, I have a 1100 and an passive probe, and I try to use it, I want to use it but everything time I do it does not work right. I always have to take it apart and clean the contacts then re-align it. I need it to work and work everything I grab it, or at least a large percentage. As it is now, overtime I use it it needs contacts cleaned.

Whats the secret to making it work reliably?
