STONEX R2
If the spot illuminates the cross, the achievable adjustment precision has been reached; if
it lies outside the limits of the cross, the direction of the beam needs to be adjusted.
If the spot on the more reflective side of the plate is too bright (dazzling), use the white
side instead to carry out the inspection.
13.12 TRIBRACH LEVELING SCREW
If the leveling screw appears flexible, adjust the two adjusting screw in the leveling screw
to tighten the screw appropriately.
13.13 RELATED PARTS FOR REFLECTOR
1. The Tribrach and Adapter for Reflector
The plate vial and optical plummet in the adapter and tribrach should be checked. Refer to
Chapter 10.1 and 10.8. for more information.
2. Perpendicularity of the prism pole
As illustrated in Chapter 10.8, mark „+‟ on Point C, place the tine of the prism pole on the
Point C and do not move during the inspection. Place the two feet tine of Bipod on the
cross lines of Point E and F. Adjust the two legs “e‟ and “f” to make the bubble on the
prism pole centered.
Set and level the instrument on Point A near the cross. Sight the 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 to another cross lines. With the same way to flex the Leg
“f” to make Point C and D on the central line of reticle.
Through the adjustment of the instrument on Point A and B, prism pole has been
perpendicular. If the bubble offsets from the center, adjust the three screws under circular
vial to make the bubble centered.
Check and adjust again until the bubble is in the center of the vial from both directions of
the prism pole.
