Five different sensitivity curves are available to select from
(curves 1 through 5). Sensitivity curve 1 is the default curve
and causes the function speed to increase or decrease
equally with an equal amount of movement of the controller
(Figure 4-55).
Selecting a sensitivity curve of 2 through 5 causes the
function speed to be reduced, from the default sensitivity
curve 1, relative to the same controller position over the full
travel of the controller (Figure 4-56). Sensitivity curve 1
(default) is the most sensitive and sensitivity curve 5 is the
least sensitive (Figure 4-55).
Adjust the sensitivity of a controller function by doing the
following:
