number and press Enter. The highlight moves to the sensor value of the selected

value.

If the sensor value entered is not between the previous breakpoint sensor value and
the following breakpoint sensor value, then the new breakpoint pair will be moved to
the position in the curve that bounds the sensor value of the new breakpoint pair. If
the pair is moved, a message will be displayed to indicate to the location to which the
breakpoint pair was moved.
