Running General Diagnostic Tests

Thermo Scientific
There are two diagnostic categories—tests and tools. Use the diagnostic tests to check the
functionality of the electrical subsystems and the PCBs. Use the diagnostic tools, specifically
the system evaluation tools, to look at the system as a whole instrument.
Before running the diagnostics consider the following:
• Did the system fail when you were running samples?
• Did problems occur after you performed maintenance on the mass spectrometer, data
• system, or peripherals?
• Did you change the system's configuration, cables, or peripherals just before the problem
occurred?
If the answer is yes to the first question, there is the possibility of a hardware failure, and
running the diagnostics is appropriate. If the answer is yes to one of the last two questions, the
problem is probably mechanical, not electrical. Check again that alignment, configurations,
and cable connections are correct before you run the diagnostics.

The diagnostic tests in the Tune Plus application test the major electronic circuits within the
mass spectrometer and indicate whether the circuits pass or fail the tests. If there is a problem
with the instrument electronics, the diagnostics can often locate it.
Note The diagnostic tests in the Tune Plus application are limited to diagnosing electrical
problems only.
