View MSD Temperatures and Vacuum
Pressure monitoring requires an optional Micro-Ion vacuum gauge (G3397A for
the 5975 and G3397B for the 5977 series).
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.
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 19 before operating the
MSD with hydrogen carrier gas.
