Reading measurements using a Leveling Rod

Height reading

Read the rod where it is intersected by the

horizontal hair. For example, the height reading

in Figure 1 is 2.0 ft.

Fig. 1

Distance Measurement

Read the rod where it is intersected by the

upper and lower stadia hairs. In Figure 1, these

readings are at 1.9 ft. and 2.1 ft. The stadia

ration is 1:100, therefore the distance from the

Fig. 2

instrument to the rod is: (2.1-1.9) x 100 = 20ft.

Angle Measurement

As shown in figure 2, sight point A and note the reading on the

horizontal circle. Rotate the level and sight point B. The angle turned

is the difference between A and B. The angle A0B = xº = A - B.
