Section 4
Preparing to Test or
Troubleshoot
INTRODUCTION
4.1.
Every time you power-up, reset the system, or change parts of
it, you should perform the following operations before using the
system to test or troubleshoot a UUT.
l
Self-tests: Ensure that the pod, probe, and
I/O
modules
are connected and working correctly. The tests check that
the devices are operating, but the tests do not check the
accuracy of the devices’ measurements.
l
Configuration: Specifies the disk drive to be used, port
configuration, error reporting, and other system settings.
Settings can
be
saved on and restored from the user disk.
l
Calibration: Adjusts the system to measure data as
accurately as possible.
An alternative to recalibration on power-up or system
reconfiguration is saving calibration data (for that
configuration) on a user disk and restoring it when
necessary.
