Alignment Data Wizard (with Flash)
If your instrument has Processor Assembly type PC6S or PC7S (see "Show System"
on page 1837) the instrument has an internal flash EEPROM that can store a backup
of the alignment data. In this case, the interface to the Alignment Data Wizard is
enhanced to accommodate this internal storage. This section details the use of this
internal flash. For details on using external storage, see the previous section
("Alignment Data Wizard (without Flash)" on page 1946).
The Alignment Data Wizard guides you through the operations of backing up or
restoring alignment data.
