FIELD CALIBRATION TEST
This laser level left the factory fully calibrated. Kapro
recommends the user check the accuracy of the laser
periodically, especially if the unit falls or is mishandled.
1. Check the height accuracy of the cross created by the lateral
(#5) and the horizontal lines.
2. Check the height accuracy of the cross created by the
longitudinal (#4) and the horizontal lines.
3. Check the accuracy of the forward vertical beam.
4. Check the accuracy of the side vertical beam.
5. Check the perpendicularity between the 2 vertical beams.
1.Checking the Height Accuracy of the cross created by
the lateral (#5) Horizontal lines.
(Up and down deviation)
1) Set up the laser on a table or on the floor between 3 walls
A, B and C . The distance between A and B should be
approximately 5 meters.
2) Position the laser level approximately 0.5 meters from wall A
and 2 meters from wall C .
3) Unlock the pendulum and press the Beam Selector (a),
twice to project all 3 lasers beams.
4) Direct the cross lines of the horizontal beam and the side
vertical beam (# 5) towards wall
A
.
5) Mark on wall
A
the center of the cross beams as
a1
,
and on wall C mark the center of the cross beam as c1
(see figure # 1).
