the reticle distinctly. Hold the other two unfixed legs with both hands and adjust position of these two legs
through observation of optical plummet. As it approximately aims at the station point, make all three legs
fixed on the ground. Adjust three leg screws of the instrument to make optical plummet collimate precisely
to the station point
3) Use circular vial to roughly level the instrument
Adjust length of three legs of tripod, make the circular vial bubble of the instrument in the middle.
4) Use plate vial to level the instrument accurately.
Rotate the instrument horizontally by loosening the Horizontal Clamp Screw and place the plate vial ①
parallel to the line connecting leveling screw A and B, and then bring the bubble to the center of the plate
vial by turning the leveling screws A and B.
②Rotate the instrument 90 , make it perpendicular to the connecting line of level screws A and B. Turn ℃
level screw C to make the bubble of the plate vial in the middle.
5) Precisely centering and leveling
Through observation of optical plummet, slightly loosen the central connecting screw and move the
instrument evenly (Don’t rotate the instrument), making the instrument precisely collimating to the station
point. Then tighten the central connecting screw and level the instrument precisely again.
Repeat this operation till the instrument collimate precisely to the measurement station point.
