Front P anel 4339B
Open K ey
The Open key is execute the OPEN correction measurement to obtain the OPEN correction
data. The 4339B uses this data to cancel the leakage of the test xture and to obtain the limit
value for the contact check function. The correction data is stored in non-volatile memory
(EEPROM). See \ P erforming OPEN Correction " in Chapter 1 for more information.
If is pressed, the following OPEN correction menu is displayed.
OpenMeas P eroforms the OPEN correction.
MeasV al Displays the OPEN correction data (OPEN measurement value).
Exit Exits the menu.
At reset, the correction data is cleared.
Calibration K ey
The Calibration key executes the calibration function. Calibration cancels the internal oset
error and the proportional error of the 4339B due to environmental temperature changes . The
calibration data are stored in backup memory . Refer to \P erforming Calibration " in Chapter 1
for more information.
At reset , the calibration data is cleared.
Comparator On/O K ey
The Comparator On/O key toggles the comparator ON and OFF . The comparator determines
the measurement result (displayed value) is within the upper and lower limits set by the
Comparator Limit key . When the comparator is ON, the Comprtr On annunciator( 9 ) will be
displayed. The comparator will yield one of the following results:
HIGH Greater than upper limit
IN Between the upper limit and lower limit
LO W Less than lower limit
N.C. (no-contact) Contact check failed (at contact check ON state)
In addition, these results are transmitted to the following destinations:
Destination Condition
Display HIGH, IN, LOW , N.C.
Handler Interface HIGH, IN, LOW , N.C.
Beeper HIGH, LOW , N.C. (when beeper mode is fail), or
IN (when beeper mode is pass)
