5. Measure the vertical distance from
the floor to each point. Calculate the
difference between distances D
to get D and distances D

6. Calculate the maximum allowed offset
distance and compare to the difference
of D and 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

D = 30,75 mm, D
P1
D = (30,75 mm - 30 mm) = 0,75 mm

(0,75 mm) - (- 0,75 mm) = 1,5 mm
1,5 mm ≤ 2,7 mm (TRUE, unit is within calibration)
