Operating Instructions for General Construction Applications
Note: A level plane of laser light is created by the rotating beam of the laser. The laser light can be
used to reference elevations with the use of a laser detector.
1.
Place the instrument on a flat, level surface such as a tripod. Setup the instrument in an
area where it can not be obstructed and is set at a convenient height.
2.
Press the “A” button. Allow the instrument to self-level.
3.
Setup a "
Benchmark
".
Note: Setup a Benchmark
During the work day, periodically check your initial set-up to ensure that the laser reference has
not moved.
Establish, at a suitable distance (furthest possible), a benchmark (reference) on a stable surface
(ie. tree, building). Periodically during the work day, check the benchmark to ensure that your
setup has not moved.
