Con Guration Key - Agilent Technologies 4349B Manual

4349B
Con guration Key
The Con guration key is used to set the beep mode and the power line frequency, and to run
the performance tests.
|Comparison results output to the beeper are classi ed as follows:
no output to beeper.
beeps when comparison result are IN for all measurement channels.
beeps when the comparison result is HI, LO, or No-Contact for any channel.
(default)
In the beeper
error occurs. In the beeper
The setting is saved in the EEPROM.
|Available power line frequency selections are 50 Hz and 60 Hz.
The power line frequency setting is stored and does not change after reset or power-o .
Once you set it, you do not need to set the line frequency again as long as the power line
frequency remains the same.
|There are ve service functions:
test front-panel keys.
test the handler output signal.
run ROM check sum program.
read-write test RAM. After the test, the 4349B resets its setting.
test EEPROM. The data stored in EEPROM is not a ected if no error detected.
If the error detected, the 4349B clears the data and restores the default data.
preforms the self-test which tests the 4349B's basic performance and displays the
results as the sum of the existing error codes.
