Focusing and Sighting
•
Before using the instrument
Turn the eyepiece to adjust the eyepiece image.
1 Using the gunsight, aim the objective lens toward the staff.
2 Gradually turn the eyepiece outward, stopping just before the
reticle cross-lines become blurred.
3 Turn the horizontal fine motion knobs until the staff is nearly
centered in the field of view, then turn the focusing knob to focus on
the staff.
4 Looking through the telescope, shift your eyes slightly up and down
and to each side.
5 If the staff and reticle show no deviation, the instrument is ready for
use.
If the staff and reticle deviate, return to step 2.
Procedure
• If deviation occurs at step 5, errors will occur when taking
measurements. Always make sure the instrument is correctly
focused.
