Each of these tests can be run individually. Information on the instrument self test and confidence check are described on page
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.
