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

the sum is not less than or equal to the

1,5 mm ≤ 1,8 mm (TRUE, unit is within calibration)
Horizontal Beam Accuracy
1. Place laser unit as shown with horizontal,
vertical, and both 90° vertical reference
laser beams ON. Mark point P
horizontal and left 90° vertical reference
laser beams cross.
