Controls and Indicators
Five light-emitting diodes (LEDs) are located in the upper right of the front panel of the mass
spectrometer. See Figure 10 and Figure 11.
The Power LED illuminates green whenever power is supplied to the vacuum system and
electronic assemblies of the mass spectrometer.
The Vacuum LED illuminates yellow when the turbomolecular pump is nearly at speed
(80 percent of its operating speed of 750 MHz), and it is safe to turn on the ion gauge. The
Vacuum LED is off if the turbomolecular pump is not at speed. The Vacuum LED
illuminates green whenever the pressure in the analyzer chamber, as measured by the ion
gauge, is at or below the value required to enable high voltages to the mass analyzer.
