4339B Front P anel
Beep Comparison results output to the beeper are classied into following modes:
OFF Does not emit a beep (no output to beeper).
P ASS Emits a beep when the comparison result is IN.
F AIL Emits a beep when the comparison result is HIGH, LOW or N.C.. (default)
Note
In the OFF mode , the 4339B does not emit a beep when a system error or
operation error occurs .

Line | A vailable power LINE frequency selections are 50 Hz and 60 Hz.
Svc | There are ve service functions .
KEY T ests the front-panel keys .
HNDL T ests the handler output signal.
CSUM Runs the ROM check sum program.
RAM T ests RAM (the read-write test). After the test, the 4339B resets the
instrument's settings .
EEPROM T ests EEPROM. The data stored in EEPROM is not aected when no
error is detected. If errors are detected, the 4339B clears the data
and restores the default data.
TEST (Self-test) | The self-test tests the 4339B 's basic performance and displays
the results as the sum of error codes of each existing error .
The 4339B also executes its self-test when it is turned ON (power-on test). The
settings of the 4339B are not aected by the self-test, except when errors occur .
