Applications
Plumbing a surface
1.Position tool close to the surface to be plumbed.
2.Turn on tool.
3.Measure distance A at a point relatively close to tool and make a note of
the distance.
4.Measure distance B at a point further away from tool and make a note of the distance.
Note: The greater the distance between the two points of measurement, the greater the accuracy.
5.Compare distance A with distance B. If distance A equals distance B, then the surface is plumb. If distance A does not equal distance B, then the surface is not plumb and should be corrected.

Transferring points with the plumb beam
1.Mark the point to be transferred (labeled A in this illustration).
2.Use the Mounting accessory or a Tripod to position the plumb down beam over point A.
3.The plumb up beam will transfer this point along a perfectly vertical axis to point B.
Leveling
1.Adjust the height of tool using the mounting accessory or a tripod so that the horizontal beam hits a reference point (labeled A in this illustration).
2.Rotate tool around its mounting axis to position the front level beam at a point of interest (labeled B in this illustration).
Note: It is possible to use the beam as a leveling instrument without marking a line through beam locations, however, some may find it more satisfying to mark the beam location at a variety of points and then create a straight line through those points to achieve a level line.

Grading |
|
1.Position tool at the highest point of the surface to be graded.
2.Turn tool on.
3.Measure distance A and make a note of the distance.
4.Measure distance B at distance X away from A and note these distances.
5.Slope = (B – A)/X
Note: To calculate Pitch, set X equal to 12”.
4. Mark point B.
Note: This process may be reversed. Plumb Transfer
