Check Accuracy of Horizontal Laser

To check the accuracy of the horizontal laser:
1. Find a horizontal site that is almost level, preferably a
concrete slab, that is ≥7.62 m (25 ft) wide with two
opposing walls to use as targets. You can also use
scrap wood as targets. See Figure 5.
2. Put the Product about 15 cm (6 in) from target
3. Point the horizontal laser at target
4. Put a mark at the point where the horizontal laser
intersects the target area.
5. Turn the Product 180 ° on its center so that the
horizontal laser intersects with target
