MEASURE WITH THE INSTRUMENT
HEIGHT MEASUREMENT
1. Set up the instrument in the middle between two measuring points A and B. Level the instrument.
2. Aim the instrument at point A and read the height A1 at the levelling rod (A1 =2,218 m).
3. Aim the instrument at point B and read the height B1 at the levelling rod (B1 = 1,950 m).
4. The height difference ∆h is definded as follows:
∆h = A1 - B1 = 2,218 m -1,950 m = 0,268 m

DISTANCE MEASUREMENT

Distance measurement with the upper and lower cross hair short lines
For distance measurements the cross hair of the instrument is equipped with upper and lower short
lines. The sector of the levelling staff that is between those two short lines is multiplied by 100 which
yields the distance between instrument and rod.
In other words:
The distance in centimeters between the short lines on the levelling rod is equal to the distance in
meters.
L (m) = ∆h (cm) x 100
14
∆h = (2,57 m - 2,33 m) * 100
∆h = 24 cm * 100
∆h = 2400 cm / 100 = 24 m
or
∆h = (2,57 m - 2,33 m) * 100
∆h = 0,24 m * 100
∆h = 24 m
