When any of the Characterize Preselector routines are initiated a
confirmation window will be seen, as shown in Figure 16-15. Once this has
been accepted do not disturb its completion by any means or the system
could become corrupted
It is also recommended that the current calibration database be backed up
before any of the Characterize Preselector routines are run, just in case an
interruption does occur and the database needs to be restored. For
information on how to back up the current database see Chapter 19,
“Post-Repair Procedures”.
