7.6 Restoring Factory Calibration
How to restore it
The factory calibration constants for all the input actuation types that can
be used with the controller are stored in its nonvolatile memory. Thus,
you can quickly restore the “Factory Calibration” for a given input
actuation type by simply changing the actuation type to another type and
then changing it back to the original type. See Table 7-6 for the procedure.
Procedure
Table 7-6 lists the procedure for restoring factory calibration.
