3-11. OPERATOR'S SELF-CHECK PROCEDURE
3-12. This section, beginning with paragraph 3-225, includes checks that allow the operator to
make a quick evaluation of the counter’s operation. These checks will fundamentally verify
the following:
Keyboard
Display and Annunciators
Memory; RAM and ROM
HP-IB
3-13, GENERAL OPERATION INFORMATION
BEFORE THE INSTRUMENT IS SWITCHED ON, ALL PROTECTIVE
EARTH TERMINALS, EXTENSION CORDS, AUTOTRANS¬
FORMERS AND DEVICES CONNECTED TO IT SHOULD BE
CONNECTED TO A PROTECTIVE EARTH GROUNDED SOCKET,
ANY INTERRUPTION OF THE PROTECTIVE EARTH GROUND¬
ING WILL CAUSE A POTENTIAL SHOCK HAZARD THAT
COULD RESULT IN PERSONAL INJURY.
ONLY THE 250V FUSES WITH THE REQUIRED RATED CURRENT
AND SPECIFIED TYPE SHOULD BE USED, DO NOT USE RE¬
PAIRED FUSES OR SHORT CIRCUITED FUSEHOLDERS. TO DO
SO COULD CAUSE A SHOCK OR FIRE HAZARD.
3-14. Power-Up/Self-Check
3-15. When the counter is turned on, an internal check is made of several major components
in its circuitry. During this cycle, all front panel segments and indicators will light momentarily,
followed by the momentary display of the instrument’s decimal HP-IB address (e.g„ HP-IB
Addr 28).
3-16. After the power-up sequence, the counter will initialize itself. Ail math and statistics will
be off, the function will be Frequency A, and the gate and cycle modes will be in Norm. All of the
input controls will be set according to their switch positions.
3-17. Any failures during the power-up cycle will disable the counter and produce a display
of numbered error or fail messages. Within the 5335A, fail messages generally indicate a hard¬
ware failure, and error messages indicate the user has attempted an improper operation. Refer to
Error Messages, paragraph 3-229.
3-18. Display
3-19. The number to be displayed is formatted into engineering notation with the digits
grouped into threes for convenient reading and an exponent with a range of ±18. When dis-
