MEASUREMENT FOUNDATION

5.2. FOCUSING AND SURVEYING

1) Point the instrument at bright uniform background.

2) Rotate clockwise the ocular ring up to the stop. After that look into the ocular of the telescope and focus the view of

reticule, slightly rotating anticlockwise the ocular ring. You should stop rotating when the view of reticule will be clear. You

shouldn’t repeat this procedure very often.

3) Point the instrument at the staff with the help of front sight (13). Then, with rotation of the knob (4) place the staff in the

center of eyesight. Remove parallax* between the staff and reticule while rotating rack-and-pinion (7).

*Parallax removal

There is no parallax, when the object view and reticule view are xed to each other even if we change eye position to the

ocular. Parallax can cause big measurement errors. That’s why you should remove it with the help of rotating rack-and-

pinion (7).

5.3. CIRCULAR LEVEL

1) With leveling screws (5) make the bubble into the center of circular level (2).

2) Rotate the instrument through a full 180˚ (pic.6).
