• After several more seconds, the Communication LED turns green to indicate that the
data system and the mass spectrometer have established a communication link. The
data system transfers operational software to the mass spectrometer.
• After three minutes, the System LED turns yellow to indicate that the software
transfer from the data system to the mass spectrometer is complete and that the mass
spectrometer is in standby mode. Or, the System LED turns green to indicate that the
mass spectrometer is functional and the high voltages are on.
You can reset the LTQ Series mass spectrometer tune and calibration parameters to their
default values at any time. This feature is useful if you have manually set some parameters that
resulted in less than optimum performance. However, Thermo Fisher Scientific recommends
that only Thermo Fisher Scientific field service engineers reset your system's parameters.
IMPORTANT
• Make sure that the system problems you are experiencing are not due to improper API
source settings (such as spray voltage, sheath and auxiliary gas flow, or ion transfer
tube temperature) before resetting the instrument parameters to their default values.
• If you reset the instrument calibration file, always repeat the calibration of the internal
electronic devices. Otherwise, all instrument calibrations might produce incorrect
calibration results.
 To reset the tune and calibration parameters to their default values
1. Open the Tune Plus window (see
2. Save a copy of the master calibration file.
3. Do one of the following:
• To restore the default calibration parameters, choose File > Restore Factory
Calibration.
• To restore the default tune parameters, choose File > Restore Factory Tune Method.
4. To calibrate or tune the mass spectrometer, follow the procedures described in the
LTQ Series Getting Started Guide.
