CALIBRATION STORAGE
The BHK-MG 40W Power Supply. maintains the calibration tables in Flash Memory until a PACK
is executed. There are six calibration areas maintained in Flash Memory: Working, Prior, Oldest,
Factory, Master, and First. The calibration password is required In order to store the calibration.
The calibration can be copied to another area using the CAL:DUMP? and CAL:COPY com-
mand. The syntax is as follows: CAL:DUMP? [source];:CAL:COPY [destination], where [source]
and [destination] refer to the areas of Flash memory where calibration data is stored, designated
as: WORKing, PRIor, OLDest, FACTory, MASTer, FIRst. Source refers to the calibration area
that is to be copied, destination to the area that the calibration will be copied into.
The ability to save to the FACTORY area is prohibited. If a user needs to overwrite the factory
calibration, a special firmware needs to be created to provide a special password for this capa-
bility. Each customer that requests this capability will be provided a password that the company
can specify. it must contain at least one alpha, one numeric and one punctuation character
(!@#$%^&*) and be at least 6 characters long and not longer than 20 characters in length. All
alpha data must be upper case and no control nor space characters are allowed.
The Master calibration should never be overwritten. Factory, Master, and First are set to the
same values when the power supply is calibrated at the factory. The Working calibration is the
active calibration. Each time a CAL:SAV is executed, the values are saved in the Working
(active) area. At the same time, the values previously stored in Working are moved to Prior, and
the values previously stored in Prior are moved to Oldest. The values previously stored in Old-
est are no longer available. Table 4-4 illustrates calibration storage and the use of the
CAL:DUMP? query and CAL:COPY command.
