TLA 711 Color Benchtop Controller Service Manual
Power-on Diagnostics. The power-on diagnostics check the basic functionality of
the controller and mainframe at every power on. If any failures occur at power
on, the screen displays the calibration and diagnostics property page. Table 6–7
lists a subset of the power on tests. Use the results of the tests to help you isolate
problems.
The power on BIOS and TLA 700 power-on diagnostic tests ensure that hardware
is installed and can be accessed by the software. The tests do not provide any
performance information, but they do provide limited diagnostic information.
The separately invoked TLA 700 mainframe diagnostics provide more extensive
tests than the power-on diagnostics.
The power on tests check the generic hardware including the keyboard, mouse,
memory, CPU, and associated peripherals. The interface circuitry between the
controller and the mainframe backplane is also tested. The interrupt lines and
trigger lines are also tested for each installed application module.
If there are no failures, you can view the results of the tests in the Calibration and
Diagnostics page under the System menu. To view the Extended diagnostics,
click on the Extended tab.

QAPlus/WIN. If the benchtop controller passes all of the BIOS tests, the primary
tree will have you run QAPlus/WIN. To run QAPlus/WIN you must have either a
working keyboard or a working mouse (or other pointing device) and have
Windows 95 running. QAPlus/WIN is a comprehensive software application to
check and verify the operation of the benchtop controller. Repair or replace any
failed component identified by QAPlus/WIN.
