Turning Off Selected Mass Spectrometer Components
There are different ways that you can turn off some or all of the mass spectrometer
components:
• Turn off individual mass spectrometer components from the TSQ EZ Tune window.
Turning off individual mass spectrometer components might be necessary when you are
troubleshooting or when you are running certain diagnostic procedures.
• Place the mass spectrometer in Standby mode. Standby is the normal condition to leave
the mass spectrometer in when it is not in use. Choose
Control > Standby
(or toggle the
On/Standby button) from the TSQ EZ Tune window to place the mass spectrometer in
standby.
• Place the mass spectrometer in the Off condition. The Off condition is similar to
Standby, except all high voltage components of the mass spectrometer are turned off.
Choose
Control > Off
from the TSQ EZ Tune window to place the mass spectrometer in
the Off condition.
• Place the electronics service switch in the Service Mode position. The electronics service
switch turns off all components in the mass spectrometer other than the +24 V power
supply, forepump, turbomolecular pump, Vent Delay PCB, and fans.
• Place the vacuum service switch in the Service Mode position. The vacuum service switch
turns off all vacuum system components, including the +24 V power supply, forepump,
turbomolecular pump, Vent Delay PCB, and fans.
• Place the right-side power panel circuit breaker switch in the Off position. Placing the
right-side power panel circuit breaker switch in the Off position removes all power to the
mass spectrometer, including the vacuum system.
• Press the System Power Off button. Pressing the System Power Off button removes all
power to the mass spectrometer, gas chromatograph, and autosampler.

Note
The communications link between the data system and the mass spectrometer
should automatically reestablish after you reset the data system. When this occurs the
Communication LED on the front panel of the mass spectrometer illuminates yellow and
then green. If the system is unable to reestablish the communications link, press the
System Reset button on the power panel of the mass spectrometer.
