Diagnostics and PCB and Assembly Replacement

Thermo Scientific
The TSQ system diagnostics can test many components of the TSQ mass spectrometer. If
there is a problem with the instrument electronics, the diagnostics can often locate the
problem. Replacing a faulty PCB or assembly can usually correct the problem. After the PCB
or assembly is replaced, the diagnostic tests are rerun to verify that the instrument is
functioning properly.
A subset of the diagnostic tools that are part of the Tune application 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 Thermo Fisher Scientific 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.
Note Three levels of protection are possible:
• No protection—All operators can access all workspaces.
• Automatic protection—Tune Master uses the default password, lctsq, to protect the
secure workspaces.
• Custom password protection—The Key Operator (or Laboratory Administrator or
Manager) can select a password to protect the secure workspaces.
If your TSQ system has been password protected, you must obtain the password before
you can access the secure workspaces (including the System Tune and Calibration
workspace). If the instrument password is lost, you must reinstall the TSQ software to
reset the default password (lctsq).
