3.8 Guidelines for Correct Results
Very short distances may be measured reflectorless in IR mode to well reflecting
targets. Note that the distances are corrected with the additive constant defined for
the active reflector.
Distance
measurement
When measurements are being made using the red laser EDM, the results may 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 road, but a vehicle passes between
the EDM and the target surface as DIST (F2) or ALL (F1) is pressed, the measure-
