Starting Up the Mass Spectrometer

Note The data system must be running before you start up the mass spectrometer. The mass
spectrometer will not operate until software is received from the data system.
1. Turn on the flows of argon and nitrogen at the tanks if they are off.

To start up the mass spectrometer
Electronics service switch and the Vacuum service switch (TSQ Quantum Access) are both in
the Service Mode position.
Power circuit breaker switch in the On (|) position, power is supplied to those mass
spectrometer components that are not affected by the Vacuum service switch and the
Electronics service switch.
Electronics service switch in the Operational position, the following occurs:
• The Power LED on the mass spectrometer front panel illuminates green to indicate that
power is provided to the mass spectrometer electronics. (The electron multiplier,
conversion dynode, ion source, and mass analyzer and ion optics RF voltages remain off.)
• The embedded computer reboots. After several seconds the Communication LED on the
front panel illuminates yellow to indicate that the data system and the mass spectrometer
have started to establish a communication link.
• After several more seconds, the Communication LED illuminates green to indicate that
the data system and the mass spectrometer have established a communication link.
Software for the operation of the mass spectrometer is then transferred from the data
system to the mass spectrometer.
• After three minutes, the System LED illuminates yellow to indicate that the software
transfer from the data system to the mass spectrometer is complete and that the
instrument is in standby.
• The Vacuum LED on the front panel of the mass spectrometer remains off until the
turbomolecular pump reaches 80 percent of its operational speed of 750 Hz. At this time
the ion gauge is turned on and the Vacuum LED illuminates yellow. The Vacuum LED
illuminates green, and the high voltage can be turned on, only if the pressure in the mass
analyzer region, as measured by the ion gauge, is below the maximum allowable pressure
of 7 × 10
-4
Torr.
