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?

  • Thanks very much for your answer. I applied the vacuum for this short-term storage.
    I was curious about the Micro-ion E gauge in our operation. In the manual, it is optional in EI mode but required in CI mode. I believe we operate it in EI mode all the time, so then can I simply operate it without the IG attached? We checked the resistance of the Gauge pins yesterday and found it's broken. It is a very expensive to buy new, so I ordered a cheap one from ebay to give a shot. Still, it would be great if I can use MSD without it.
