Note
Each of these tests can be run individually. Information on the instrument self test and
confidence check are described on page 2-68. Refer to "Test Descriptions", on
page 2-70 if you require a description of the other tests.
When an individual test is selected, the message "Testing..." appears next to the
name of the test. When the test is complete, the message "Testing..." is replaced
by either the message "Passed" or "Failed". This pass/fail indication excludes
the keyboard test and the bitmap display test, both of which rely on your interaction to
detect a failure.
When the individual test is complete, the result is displayed until
the self test failed, information about the failure is displayed on the screen.
