5. Verify the distance readings are within +6 inches of the
actual distance measurement.
DIFF DISTANCE (Differential Distance Test) –
Optional Test
MPH units only—Metric units are NOT EQUIPPED with
this feature.
Prepare two flat 1'x1' or larger targets, preferably
painted with a flat white paint. Plywood or particleboard is
suitable. Place the targets at two precisely known, integer
feet, distances along the same line of sight. You may find
it useful to place the further target higher than the closer
target. Use whole number distances such as 50 or 75 feet,
not 50.26 or 74.87. It is strongly recommended that
distances between 50 and 100 feet be used for practical
reasons and that the zero foot point (measurement point)
be carefully marked. The minimum target separation
should be 10 feet. Position the Pro-Lite so that the front
face of the unit is precisely placed at the zero foot point.
You may find that using a tripod or monopod will be
useful, but is not a requirement.
Enter the DIF-TEST mode by pressing MENU and
selecting the Menu item. The following screen displays:
Diff Distance
Dist1
Carefully range to either of the two targets being sure
to hit only that target. The range appears in the area next
to "Dist1" text. After a suitable range is obtained, press
TEST / ▼ ARROW to accept this reading.
