Checking square (Accuracy of 90° angle between the
level beams)
1. Use a room that is at least 5 meters long. Mark a point
(A1) on the floor near the wall at one end of the room.
2. Set up the laser so that its down beam is over point A1.
Make sure the front level beam points toward the far wall of
the room.
3. Mark a dot at the center of the room using the target and
transfer the dot location to the floor (A2).
4. Mark a dot on the far wall (A3).
5. Set up the laser so that its down beam is over point A2 and
the front level beam points to the A3 mark.
6. Mark the location of the square beam (A4) on the side wall.
Note: To ensure accuracy, the distances from A1 to A2,
A2 to A3, and A2 to A4 should be equal.
7. Turn the unit 90° so that the front level beam aligns with
point A4, while down beam is still over point A2.
8. Mark the location of the square beam on the wall and
transfer its location onto the floor (A5) as close as possible
to point A1.
9. Measure the distance between points A1 and A5. If the
distance is less than or equal to 3mm (while the distance
from A2 to A1, A3, A4 is approximately 2.5 m), then the
unit is calibrated.
10. You can check the angle to the other square level dot in
the same manner.
