6.1 Measurements
Description The 3D Disto is a combination of a precise laser distance metre (LDM) and angle
encoders. Targeting with the visible red laser beam allows measurement of the
distance between the 3D Disto and the target and of horizontal and vertical direc-
tions toward the target. Measurements are used to establish the relation between
different targets, such as horizontal distances, tie distances, height differences to
determine room dimensions, angles from wall to wall, areas, volumes, plumb points,
or other features.
The 3D Disto supports measuring and targeting even in difficult situations such as
targeting over long distances, at inaccessible targets or in bright light conditions. A
built-in tilt sensor ensures that measurements relate to true horizon or true plumb
line, defined by gravity.
