Select
Pump
from the
Options
menu.
This starts the forepump and the turbomolecular pump. Watch the vacuum
gauge readout and allow time for the gauge to achieve 4 x 10-5 Torr.
8.
Observe the displayed masses.
Mass 4 (helium) should be much larger than mass 18 (water), which should be
larger than mass 28 (nitrogen), which should be about 4 times larger than mass
32 (oxygen).

If the nitrogen and oxygen are larger it indicates an air leak, which could
damage the filament. Immediately click
Press for Standby
to turn off the
filament.
10.
If a leak exists, locate and fix it.
Typical areas to check for leaks are around fittings and areas under vacuum.
