The Master calibration should never be overwritten. Factory, Master, and First are set to the
same values when 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 Oldest are no longer available. Table 4-2
illustrates calibration storage and the use of the CAL:COPY command.
