Description of the device
The laser distance measuring device is used to determine
distances, areas and volumes in interior spaces. Indirect
measurements are carried out employing the Pythagoras
function.
The device is equipped with separate operating elements (2) for
the different measuring functions. The multi-line and optionally
also illuminated display (3) indicates the determined values.
Owing to the dust- and splash-proof housing (IP54), the device is
also suited for use on construction sites.
Operating elements
Measuring distance
The range of the device can be gathered from the Technical data
chapter.
Under certain conditions – e.g. at night, in twilight or when the
target is hidden in the shade – greater distances are possible
even without target plate. During the day use a target plate to
increase the distance for poorly reflecting targets.
Target surfaces
There might be measurement errors, when the laser encounters
colourless liquids (e.g. water), dust-free glass, styrofoam or other
semi-permeable materials. The measurement results could also
be falsified, if the laser encounters a high-gloss surface and is
deflected by it. Non-glossy, non-reflective or dark surfaces can
extend the measurement duration.
