Commands
Self-test
More Commands/Self-test
The Self-test command allows you to test subsystems in the programmer,
verifying proper operation or isolating possible problem areas.
An automatic self-test is also performed each time the programmer is powered
up. If errors occur during the powerup test, the Self-test screen is displayed,
showing the areas that failed.
Some self-tests (such as User RAM test) can be disabled so they are not
checked during powerup. Disabling and enabling self-tests is done in the
More Commands...Interface menu.
Note: For details (help) on the function of each self-test, move the cursor
to the test you want information about and press F3.
For information on how to verify the performance of your programmer,
refer to Appendix A.
Halting a Self-test
You can stop a self-test at anytime during its operation by pressing CTRL+Z.
Running the Self-test
To perform a Self-test, follow these steps:
1. Make sure the device socket is empty.
2. Select the test mode. You can select either one-pass or continuous testing.
To toggle modes, move the cursor to the Test Mode field and press SPACE.
One Pass testing runs the specified test once. Continuous testing runs the
specified test until there is a failure or until you halt the procedure by
pressing CTRL+Z.
Note: There may be a delay before the programmer responds to the
Ctrl+Z if the programmer is running the system RAM test.
3. To test all hardware, move the cursor to the Perform All Tests prompt
and press ENTER.
To test a particular item, move the cursor to the desired test and press
ENTER.
Interpreting Self-test Results
Four conditions are used as status indicators on the self-test screen:
? UNTESTED
P PASS
F FAIL
- NOT INSTALLED
When testing begins, a ? appears next to the untested areas. As each
test completes, either P (pass) or F (fail) appears next to the test name,
showing the results of the test performed. If a hardware item is not installed,
a — appears.
During testing, the message area of the self-test screen indicates that testing
is in progress. During the System RAM test, the Remote and the Terminal
indicators blinks to indicate that testing is in progress.
