Micro-Ion gauge

hello, Micro-Ion gauge in our 5975 MSD is blinking between green and red. I took it off of the spectrometer for a repair and capped the vacuum port. can the MS be remained in atmosphere for a while after vent or should it be kept under vac?

  • Thank you very much! I'll make sure to have those items correctly. Our instrument (5975C MSD) has been in idle condition for over an year but under vacuum up until recently I started it again. My real issue is autotune fail. The tune fail symptom is Ent lens offset that is out of range (64.26). I found in this Community that a similar case has been reported and resolved by disassembly and cleaning of HED and/or ion source. Am I right on the track? If you have any other opinion, please let me know.
