If your measurement is greater than the Allowable
Distance Between P1 & P2 for the corresponding
Distance (D1) in the following table, the laser must be

Horizontal Line Accuracy - Level
Checking the level of the laser's horizontal line requires a flat
vertical surface at least 30' (9 m) wide.

Place the laser at one end of the wall as shown
in Figure
#1, and turn the laser ON.

Vertical Line Accuracy - Plumb
Checking the plumb of the laser's vertical line.
1.
Measure the height of a door jamb (or a reference point on
the ceiling) to get height D1 (Figure
