Hello all,

I'm working on 13 year old Varian 4000 MS. Today I've got the communicate "the trap filament is not being properly controlled". It seems strange because all diagnostic tests were ok, and the filament is new - it was changed in last week (the last one was broken). I tried to turn off/on the electronic switch, as was suggested by the service, but it didn't help. Diagnostic tests are still ok, but when it comes to acquisition the communicate appears again.

If anyone can help it would be great, because I can't finish analysing my samples and I'm really in total despair.
