Chapter 2 Operating Your Universal Counter
Front Panel Display Messages
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.)
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.
Possible individual failure messages are:
FAIL: DISP
FAIL:CPU
FAIL: ROM
FAIL:RAM
FAIL: EEPROM
FAIL: HP-IB
FAIL: QSPI
FAIL: FPGA
FAIL: FR END
FAIL: MEAS
FAIL: INTERP
In addition, the following power-up message may be displayed:
