4263B
If the dierence between the LO AD measurement value and reference value is more than
20 %, the 4263B displays
\WARNING: Out Of Limit "
This is only a W ARNING message , so the LO AD correction data will still be used.
The LO AD correction data is saved in non-volatile memory (EEPROM), and is cleared when the
4263B is reset. It is not cleared when the *RST command was executed from GPIB .
Comparator K ey
The Comparator key toggles the comparator function ON and OFF . The comparator determines
whether the measurement result (displayed value) is within the upper and lower limits set by
the Primary and Secondary Comparator Limit keys . When the comparator function is ON, the
Comptr On annunciator will be displayed. The comparison results can be displayed on the
LCD display , can be output to the handler interface , or can be revealed by the beeper .
The comparator will yield one of the following results:
HI (high) : Greater than upper limit
IN (in) : Between the upper limit and lower limit
LO (low) : 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
Comparison Display : HI, IN, LO , N.C.
Handler Interface : HI, IN, LO , N.C.
Beep (F AIL mode) : HI, LO , N.C.
(P ASS mode) : IN
Note
When the measurement parameter or the deviation mode is changed, the
comparator function is automatically turned OFF .
