Guidelines for Correct Results
Distance measure-
ment
When measurements are being made using the red laser EDM, the results can be
influenced by objects passing between the EDM and the intended target surface. This
occurs because reflectorless measurements are made to the first surface returning
sufficient energy to allow the measurement to take place. For example, if the
intended target surface is the surface of a building, but a vehicle passes between the
EDM and the target surface as the measurement is triggered, the measurement may
be made to the side of the vehicle. The result is the distance to the vehicle, not to
the surface of the building.
