it during the inspection. Place the two feet tine of Bipod on Point E and F on the cross lines. Adjust
the two legs to make the bubble on the prism pole centered.
Set and level the instrument on Point A near the cross. Sight tine of Point C with the center of reticle, and fix the
Horizontal Clamp Screw. Rotate the telescope upward to make D near the horizontal hair. Flex the prism pole Leg
e to make the D in the center of reticle. Then both Point C and D are on the central line of reticle.
Set the instrument on Point B on another cross lines. With the same way flexing the Leg f to make Point C and D
are on the central line of reticle.
Through the inspection by the instrument on Point A and B, Prism pole has been perpendicular. If then the bubble
offset from the center, adjust the three screws under circular vial to make the bubble centered, refer to Chapter 20.2.
Check and adjust again until the bubble is in tche center of the vial from both directions.
