Scope Alignment Test
This test ensures the accuracy of the UltraLyte’s
targeting mechanics, and should be performed
periodically.
1. Put the instrument in test tone mode. Press the
Test/Options button repeatedly until the display
reads "tt," which stands for
test tone
. When test
tone mode is active, pressing the trigger
generates an audible tone. The tone’s pitch is
related to the strength of the laser pulse
returned to the instrument: a high tone indicates
a strong return, a low tone indicates a weak one.
2.
Select a target.
Choose a prominent target with
definitive horizontal and vertical edges. The
target’s reflective qualities and distance from
you should be such that you can clearly hear a
change in the pitch of the test tone when you
pan the instrument over the edges of the target.
(A telephone pole is an excellent choice.) Make
sure there is nothing behind the target the
instrument might detect, so you know without
doubt that any change in pitch is due strictly to
the target.
3.
Scan the target.
Press and hold the trigger while
panning the instrument across the target. The
tone changes pitch when the instrument
acquires the target. The highest pitch—the “on
target” tone—should occur when the scope's red
aiming dot is centered on the target.
Scan the target both horizontally and vertically,
making certain the pitch decreases evenly off
each side of the target. If there is any
discrepancy between the “on-target” tone and
the position of the red aiming dot, perform the
realignment procedure (see Realigning the
Scope on page 54).
Note: When checking vertical alignment to a
close target, be aware of the offset between the
center of the scope and the center of the
transmit lens, which is 2 inches.
