Procedure
Example: Self-Test
Manually you can use the Performance Test Record as described on the previous
page in the section "Recording Your Test Results".
See Table D-1, Recommended Test Equipment, for test equipment requirements.
You should complete the Performance Verification tests at one year intervals. For
heavy use or severe operating environments, perform the tests more often.
The procedure in this section is used to quickly verify that the digitizer is
functioning. This test should be performed anytime the user wants to verify that the
digitizer is connected properly and is responding to basic commands.
This test verifies that the digitizer is communicating with the command module,
external controller, and/or external terminal by accepting the *TST? common
command and performing a digitizer self-test. You have a high confidence (90%)
that the digitizer is operational if self-test passes.
1. Verify that the digitizer and command module or system resource manager
(e.g., embedded controller) are properly installed in the mainframe.
2. Remove any input connections to the digitizer input terminals. Errors may
be induced by ac signals present on the digitizer's input terminals during a
self-test.
3. Execute the digitizer self-test using the *TST? command.
4. A "0" returned means self-test passed with no failures. Any other value
returned is a self-test error code and means a failure was detected. See the
TEST command in Chapter 3 for obtaining information about self-test
failures. See Appendix C and the TEST command in Chapter 3 for self-test
error codes.
Note
If an incorrect address is used, the digitizer will not respond. Verify proper
address selection before troubleshooting.
This BASIC example performs a digitizer self-test. Any number other than 0
returned indicates a test failure. See Appendix C and the TEST command in
Chapter 3 for self-test error codes.
