Realigning the Scope
The scope may become misaligned by a heavy blow
to the instrument. The procedure in the table below
corrects the alignment. The point of the procedure is
to align the laser’s point of impact with the scope’s
red aiming dot, using sound to indicate when the
scope is on target.
To align the scope properly, you need:
• Two metric Allen wrenches
to expose and turn
the scope adjustment screws, one 2.5mm and
one 1.5mm.
• A target
at which to aim the instrument.
• A highly stable base
for the instrument. A tripod
is recommended.
Target Selection
Choose your alignment target carefully. The target
should be at least 700 ft. (200 m) away. It should be
a prominent target with definitive horizontal and
vertical edges that will cause a clearly perceivable
change in the pitch of the test tone (a telephone pole
is an excellent choice). Make certain there are no
background objects that the instrument might detect.
