Vertical Laser Accuracy

To check the accuracy of the vertical laser:
1. Find a door jamb that has ∼2.29 m (7.5 ft) clearance on both sides of the door.
2. Put a center mark on the door header an equal distance from both sides of the door jamb.
3. Put a cross mark (mark 1) on the floor centered on the mark on the door header. See Figure 9.
4. Put a second cross mark (mark 2) ∼2.29 m (7.5 ft) from mark 1. Use the vertical laser to make sure that
mark 2 is centered on the door header and intersects mark 1.
5. Put the Product on mark 2 with the vertical laser on.
6. Put a third cross mark (mark 3) on the floor ∼4.57 m (15 ft) from the Product. Use the vertical laser to make
sure that mark 3 is centered on the door header and intersects mark 1.
7. Put a cross mark  on the door header above mark 1.
8. Move the Product to mark 3 and align the laser so that it intersects the centers of marks 1 and 2.
9. Put another cross mark  on the door header above mark 1.
10. Measure the distance between the center points of the two cross marks.
If the distance is ≤3 mm at 10 m (1/8 in at 30 ft), the laser is within calibration accuracy.
