9. Instrument Shutdown
Procedure 1: (normal shut-down)
- The green button is located on the right side of the vacuum
chamber next to the specimen exchange chamber isolation valve
lever (refer to Figure 3.1). The green button light indicates
that the sample exchange airlock is at atmosphere. If this
button is not lit, press the button to vent the airlock.
Procedure 2: (run overnight)
FAILURE TO DO THIS CAN SEVERELY DAMAGE THE INSTRUMENT.
