Reticle

PROCEDURE Check 1: Perpendicularity of the reticle to the horizontal axis
1. Carefully level the instrument.
2. Align a clearly visible target (the
edge of a roof for example) on
point A of the reticle line.
3. Use the telescope fine motion
screw to align the target to point B
on a vertical line.
If the target moves parallel to the
vertical line, adjustment is
unnecessary. If its movement
deviates from the vertical line,
have your Sokkia service
representative adjust it.
PROCEDURE Check 2: Vertical and horizontal reticle line positions
• Perform the check procedure under slightly hazy and weakly scintillating
conditions.
1. Install a target at a point about
100m in the horizontal direction
from the SET.
2. Level the instrument carefully, turn
on the instrument's power.
