Power-Up/Self Test Messages
The following sequence occurs when you turn on the Counter:
1. All of the vacuum-fluorescent display segments and the indicators
(or LEDs) are illuminated for the power-up test.
2. If all tests pass:
SELFTST: PASS
will be displayed (See NOTE below).
3.
HP-IB AT X
will be momentarily displayed (where X represents the
HP-IB address number), then the Counter will start taking
measurements. (Note: Earlier versions of the Counter do not display
the HP-IB address.)
NOTE
If there is a failure, each test that fails will display a failure message, and
SELFTST: FAIL
will be displayed. You must press any key in order for the
Counter to go on.
