Height error.
Point “O” does share the same height as the laser output source of the instrument,
but the height of the laser height needs to be corrected.
Adjustment required:
First attempt a small error adjustment using a hexagonal wrench key (3 mm).
Adjust the horizontal laser
line until it matches the reference line (AOB).
If further adjustment is needed, use the two screws indicated in the figure below. The middle screw
needs to be loosened first only by little. Then move the horizontal laser line toward the reference line by
either tightening or loosening the two outer screws. Then secure the adjustment be tightening the
middle screw. If needed, make small adjustments again using the hexagonal nuts.
