A maximum (or minimum) point is detected whenever an amplitude
excursion greater than half of a division occurs. The half of a division
excursion requirement must be satisfied on both sides (left and right) of the
peak (or minimum). The maximum (or minimum) point must be
>-60
dE3.
See Figure 4-4.

When the maximum or minimum point is at or near either edge of the
display, the excursion requirement is satisfied by a half of a division excursion
on just one side of the maximum (or minimum). See Figure 4-5.
