PPC and MicroATX PC Diagnostics
The primary diagnostics for the instrument are the power-on diagnostics, the
CheckIt Utilities diagnostics, and the instrument diagnostics. Procedures for
running these diagnostics are described next.
The power-on diagnostics check the basic functionality of the instrument at every
power on. If any failures occur at power on, the screen displays the calibration
and diagnostics property page. Table 6--6 lists a subset of the power on tests. Use
the results of the tests to help you isolate problems to system modules.
The power on tests ensure that hardware is installed and can be accessed by the
software. The tests provide limited diagnostic information, but do not provide
any performance information. The instrument 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 interrupt lines and trigger lines
are also checked.
If there are no failures, you can view the results of the tests in the Instrument
Diagnostics page under the Utilities menu.
