Press SELECTION COMPLETE when done.
Point Pattern
This allows you to decide between a Single Point (X, Y) or a Grid point pattern (X, Y). Single Point (X,
Y) is used to create test points one at a time on the test field by entering the “X” and “Y” coordinates
for each point. The Grid (X, Y) pattern is used to place an entire square or rectangular grid of points
on the field at one time. Each Custom test can contain a maximum of 248 test points.
When entering single points, the “X” coordinate designates the distance in degrees the point will be
located to the left or right of the center of the test field. For example, an entry of “15” will place the
point 15 degrees to the right of the center, while an entry of “-10” will place the point 10 degrees to
the left of the center.
The “Y” coordinate designates the distance in degrees the point will be located above or below the
center of the test field. For example, an entry of “6” will place the point 6 degrees above the center,
while “-12” will place the point 12 degrees below the center. The combination of “X” and “Y”
coordinates locates the point in the test pattern.
