for the 5975 and G3397B for the 5977)..
Select Instrument Status in the windows area and click MSD to display the MSD’s
actuals values including the source and quad temperatures and quad manifold
vacuum pressure.
WARNING
If you are using hydrogen as a carrier gas, do not turn on the Micro-Ion vacuum
gauge if there is any possibility that hydrogen has accumulated in the analyzer
chamber. Read “Hydrogen Safety”on page 18 before operating the MSD with
hydrogen carrier gas.
