With the circular bubble centred 
and adjusted, the line of sight 
should be horizontal.
Checking (see example):
1. Choose a distance of appr. 30 m 

within a gentle terrain.

2. Set up a staff at both final points 

(A, B).

3. Set up the instrument at point I

1

 

(halfway between A and B, just 
pass it down) and centre the 
bubble.

4. Read both staffs.

reading on A = 1.832 m
reading on B = 1.616 m

Δ

H = A - B = 0.216 m

5. Set up the level about 1 m from 

staff A

6. Read staff A (eg.: 1.604 m)
7. Find nominal reading B; eg.: 

Reading A - 

Δ

H = 1.604 m - 

0.216 m = 1.388 m

8. Read staff B, compare nominal-

/actual- reading.

)

When the difference 

nominal-/actual- reading is more 
than 3 mm the line of sight must be 
adjusted.
1. Turn the adjusting srew until the 

middle hair gives the required 
reading (eg. 1.388 m).

2. Check line of sight again.

)
