The Rotary Laser leaves the factory fully calibrated. Kapro
recommends that the level is checked regularly, and after the
unit has been dropped or mishandled.
Horizontal Plane Calibration Test
1. Set up the Rotary Laser approximately 150ft (50m) from a wall
or measuring staff.
2. Position the Rotary Laser so that the X-axis is pointing in the
direction of the measuring staff or wall.
3. Turn on the Rotary Laser.
4. Mark the height of the laser beam on the wall or measuring
staff (h1).
5. Rotate the Rotary Laser 180°.
6. Mark the height of the laser beam on the wall or measuring
staff (h2). The difference between the heights should not
exceed 3/8 inch (10mm).
7. Repeat Procedure for the Y-axis.
