6.3. DISTANCE MEASURING ALONG THE STADIA HAIR
Stadia hair can be used for distance measuring and for setting the instrument in the center of the line between two
points.
1) Point at the staff and calculate the number of centimeter division between two stadia hairs (Pic.17).
Рiс.17
2) Value is equivalent to the distance in meters
between the staff and the instrument.
Example:
If centimeter division = 32 cm, horizontal distance from
the center of the instrument A to the staff B is 32 m
plus constant correction of the instrument (32m + 100
mm) (Pic.18).
