Checking square (Level to square beam 90° calibration)
1. Find a room at least 5m long. Mark a point (A1) on the floor at one end
of the room.
2. Set up the laser so that its down beam is over point A1. Make sure the
level beam points toward the far end of the room.
3. Mark a point (A2) on the floor at the center of the room using a target to
transfer the level beam location to the floor.
4. Mark a point (A3) on the far wall or transfer the level beam location to
the floor.
5. Move the unit to point A2 and align the level beam to point A3 again.
6. Mark the location of the square beam (A4) on the floor.
7. Note: To ensure accuracy, the distances from A1 to A2, A2 to A3, and A2
to A4 should be equal.
8. Turn the unit 90° so that the level beam aligns with point A4, without
moving the point A2.
9. Mark the location of the square beam (A5) on the floor as close as
possible to point A1.
10.Measure the distance between points A1 and A5. If the distance is less
than or equal to 3mm, then the unit is calibrated.
