To Run the Self-Test Routines
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 powerup 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 powerup
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.
You can also specify that failure messages be sent to a printer, the RS-232,
and the HP-IB—if in talk-only (
TST PRINT: ON
or
OFF
).
