Turning Off Selected Mass Spectrometer Components

Thermo Scientific
If possible, use the Windows restart procedure to shut down and restart the data system so
that Windows can properly close applications and save changes to files.
Note The communications link between the data system and the mass spectrometer
should automatically reestablish after resetting the data system. When this occurs the
Communication LED turns yellow and then green. If the system is unable to reestablish
the communications link, press and hold the Reset button for three seconds.
 To restart the data system by using Windows (soft reboot)
1. On the Windows taskbar, choose Start > Shut Down.
2. Select Restart, and then click OK.
 To restart the data system by using the power button (hard reboot)
1. Press the power button on the data system computer.
2. Wait at least 20 seconds after the computer shuts down.
3. Press the Power button again.
There are five ways that you can turn off some or all of the mass spectrometer components:
• Turn off individual mass spectrometer components by using the Tune Plus window.
Turning off individual mass spectrometer components might be necessary when
troubleshooting a problem or running certain diagnostic procedures.
• Place the mass spectrometer in standby mode, which is the normal state to leave the mass
spectrometer in when it is not in use.
• Place the mass spectrometer in off mode, which is similar to standby, except that all
high-voltage components of the mass spectrometer are off.
• Place the electronics service switch in the Service Mode (down) position so that you can
perform maintenance procedures involving nonvacuum system components of the mass
spectrometer.
• Turn off the Main Power switch, which removes all power to the mass spectrometer,
including the vacuum system.
Table 5 summarizes the On/Off status of mass spectrometer components, voltages, and gas
flows.
