Device description
The laser distance measuring device BD11 is used to determine
distances, areas and volumes in interior spaces. Indirect
measurements are carried out employing the Pythagoras
function.
The multi-line, illuminated displayindicates the determined
values.
Owing to the dust- and splash-proof housing (IP54), the device
is also suited for use on construction sites.
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 result may
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.
