For the 7000 Triple Quad GC/MS, in the Triple Quadrupole Vacuum Control, the turbo speed is 100%, and the Rough Vac is 1.44E+2 mTorr. When pressed "Pumpdown" the High Vac is still off. How to Pumpdown?
I'm sure you've tried, but when we have issues like this with our 6545XT QToF, restarting the PC and hard restart (power-off/power-on) for the MS works every time.
Sounds like your MS is pumped down but high vacuum gauge not giving a value. Close sw and then power cycle MS.
