4. Rotate laser unit 180° and mark point P
5. Measure the vertical distance from
the floor to each point. Calculate the
difference between distances D
to get D and distances D

the sum is not less than or equal to the
calculated maximum offset distance the
unit must be returned to your Stanley
Distributor.
Example: D = 10 m, D
