Checking the Horizontal Leveling Accuracy
A free measuring distance of 15 ft on a rm surface in front of two walls A and B is required for the check.
1. Mount the tool onto a tripod, or place it on a rm and level surface 6'' from wall A. Switch the tool on and set the lock to
"unlock".

2. Sketch a vertical line on wall A and point the front laser so it lines up with the sketched line. Allow the tool to level in.
Mark this point on the wall (point

).
