If the answer is yes to either of the last two questions above, the problem is probably
mechanical, not electrical. Verify again that alignment, configurations, and cable connections
are correct before you call the service engineer. Keep careful notes documenting the nature of
the problem and the corrective steps you have taken. If you are not successful in correcting the
problem, you can email this information to your field service engineer. The Field Service
department can then do a preliminary evaluation of the problem before an engineer arrives at
your site.
Note A subset of the diagnostic tools targets specific functions of the entire mass
spectrometer. In general, these system evaluation tools do not contain pass or fail criteria
nor do they rate the performance. Instead, they provide data that can be interpreted by a
service engineer. Because the system evaluations examine complex interactions, the service
engineer uses the data in conjunction with other tools and tests to form a diagnosis.
 To run diagnostics
Note Some diagnostic tests require that you infuse calibration solution.
1. Open the Tune window.
2. Click the Diagnostics icon (lower left corner) to open the Diagnostics pane.
3. Select which diagnostics you want to run and click Start.
The data system displays the status of the diagnostics in the Tune window.
Fuses protect the various circuits by opening whenever an overcurrent condition occurs. On
the mass spectrometer, an open fuse indicates a failed board or electronic module that a
service engineer must replace.
The electronic assemblies that control the operation of the mass spectrometer are distributed
among various PCBs and other modules located in the tower, in the embedded computer, and
on or around the vacuum manifold of the mass spectrometer.
CAUTION Thermo Fisher Scientific service is required. Because the electronic
assemblies are close-packed to minimize the size of the instrument, only a service engineer
can replace electrical components (that is, fuses, PCBs, power supplies, and so on).
