Controls and Indicators
Six LEDs are located at the upper right side of the front panel of the mass spectrometer.
See Figure 9 (TSQ Vantage, TSQ Quantum Access, or TSQ Quantum Access MAX mass
spectrometer) and Figure 10 (TSQ Quantum Ultra mass spectrometer).

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 is at or below the value
required to enable high voltages to the mass analyzer (7 × 10
–
4
Torr).
The Communication LED illuminates yellow when the mass spectrometer and the data
system are trying to establish a communication link. The Communication LED illuminates
green when the Ethernet communication link between the mass spectrometer and the data
system has been made.
The System LED illuminates yellow whenever the mass spectrometer is in standby—that is,
high voltage is not supplied to the ion source, mass analyzer, or ion detection system, but the
mass spectrometer power is on. The System LED illuminates green whenever the high voltage
is enabled and the system is in the On state. High voltage is enabled if the analyzer chamber is
below 7×10
–
4
Torr.
The Scan LED flashes blue whenever the mass spectrometer is on and is scanning ions.
The syringe pump LED illuminates green whenever the syringe pump is pumping. The LED
illuminates yellow if the syringe pump is at the end of its travel.
