5.8 Turning Off Selected MS Detector
Components
There are five ways that you can turn off some or all of the MS detector
components
• Turn off individual MS detector components from the Tune Plus window.
Turning off individual MS detector components might be necessary when
you are troubleshooting or when you are running certain diagnostic
procedures.
• Place the MS detector in Standby. Standby is the normal condition to
leave the MS detector in when it is not in use. Choose
Control > Standby
(or toggle the On/Standby button) from the Tune
Plus window to place the MS detector in Standby.
• Place the MS detector in the Off condition. The Off condition is similar to
Standby, except all high voltage components of the MS detector are
turned off. Choose Control > Off from the Tune Plus window to place
the MS detector in the Off condition.
• Place the electronics service switch in the Service position. The
electronics service switch allows you to perform maintenance procedures
involving non-vacuum system components of the MS detector.
• Place the main power circuit breaker switch in the Off (O) position.
Placing the main power circuit breaker switch in the Off (O) position
removes all power to the MS detector, including the vacuum system.
The on/off status of MS detector components, voltages, and gas flows is
summarized in Table 5-1.
