Tory, 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 Master calibration should never be overwritten. Factory, Master, and First are set to the
same values when a BIT 4886 card is factory-installed in a BOP power supply. The Working cal-
ibration 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 Oldest are no longer available. Table 4-6 illustrates calibration storage and the use of
the CAL:COPY command. An example is shown in PAR. 4.1.2
