Eyepiece Adjustment
Point the telescope to a uniform light surface such as
a wall or a piece of paper. Turn the eyepiece until the
cross hairs are sharp or distinct.
Target Image Focusing
Use the gunsight to aim the objective lens at the staff.
Turn the horizontal fine motion screw until the staff is
nearly centered in the field of view and then turn the
focusing knob to focus on the staff. Ensure that staff
image and reticle are sharp or distinct.
Power ON
The instrument is ready to measure.
Technical hints:
• First check and adjust the electronic and optical
line-of-sight errors, then the circular level on the
instrument and then the staff: before starting work
in the field, after long storage periods, after long
transportation.
• Keep the optics clean. Dirt or condensation on the
optics can limit measurements.
• Before starting work, let the instrument adjust to the
ambient temperature (approx. 2 minutes per °C of
temperature difference).
• Avoid measuring through window panes.
• Staff sections have to be fully extended and prop-
erly secured.
Measurement Preparations
• Touching the upper third of the tripod, can damp
vibrations at the instrument due to wind.
• Use the lens hood to cover the objective when
backlight disturbs.
• Evenly illuminate the measuring area of the staff
with a flashlight or spotlight in darkness.
