HOW TO SET SLOPES (FALLS/GRADES) 

Working Example 2 (when you do NOT know the grade to set)

To make the next adjustment, use the remote control if distance “

D

” is less than 20m; or a 

colleague closer to the laser with the remote control, if “

D

” is more than 20m. (Please note that 

the remote control range outdoors is a maximum of 20m).

Press X/Y button once to change the axis to Y, then press and hold the + button to move the 

laser beam down the measuring staff  until a continuous tone is heard. 

The laser is now set at the desired Fall.

Note: If the laser is switched OFF and ON again, this value is lost; as the laser reverts back to 

auto level.

Keep the detector clamped in place on the measuring staff  & by moving between covers 

A

 & 

B

, 

keeping a continuous tone on the detector, the ground can be cut away at the base of the staff , 

following the grade set by the laser.

Obviously, allowance must be made for the actual depth of the pipes’ exit & entry positions in 

each manhole.

Grade Ratio

As an example, if distance “

D

” is 20m (20,000mm) & fall “

F

” is 250mm, the formula shown below 

determines the Grade ratio:

Distance “

D

” in mm / Fall “

F

” in mm = Grade ratio.

i.e. 20,000/250 = 

80

A 

1:80

 Grade (fall) is used typically for a foul drain run.
