corrections for a frequency converter head are automatically loaded
("...Default.csv"). These corrections are defaults for the specific head,
to improve nominal accuracy of the amplitude readings, but this accuracy
is not specified. Press Edit SA, when you want to view or edit the
corrections using the SA mode corrections. This state stops all
auto-loading of the default corrections. Refer to step 8.
The other non-SA supported modes do not allow viewing or editing of the
corrections, but they all share the same corrections.
Therefore, any manual changes to the corrections (using SA via Edit SA)
are then used by other supported modes (RTSA/IQA/OTA) as well.

editing Edit SA was used). Default is OFF.
