passed, proceed to the following section.
Overview of the Self-Test Routines
The Utility menu includes the following three self-test menu items:
•
TEST LOOP:
•
TST PRINT:
•
TEST:
The Counter includes several self-tests. Some self tests are performed at
the power-up of the Counter. Some of these self tests can also be invoked
from the Utility menu. Other tests can also be invoked from the Utility
menu, but a slightly different test is performed. For example, a power-up
self test might work regardless of connections to the inputs while a Utility
menu self test may require a specific signal to be connected. Some self tests
can only be invoked from the Utility menu, for example, the keypad test.
You can specify that the tests should loop forever (
TEST LOOP: ON
or
OFF
) or until any key is pressed.
