INFLUENCE EFFECTS ON THE MEASURING
RESULT
Due to physical effects, faulty measurements cannot
be excluded when measuring on different surfaces. In-
cluded here are:
– Transparent surfaces (e.g., glass, water),
– Re
fl ecting surfaces (e.g., polished metal, glass),
– Porous surfaces (e.g. insulation materials),
– Structured surfaces (e.g., roughcast, natural stone).
Also, air layers with varying temperatures or indirectly
received re
fl ections can affect the measured value.
ACCURACY CHECK OF THE MEASURING
TOOL
The accuracy of the measuring tool can be checked
as follows:
– Select a permanently unchangeable measuring sec-
tion with a length of approx.
3 to 10 metres; its length must be precisely known (e.g.
the width of a room or a door opening). The measur-
ing distance must be indoors; the target surface for the
measurement must be smooth and re
fl ect well.
– Measure the distance 10 times after another.
The deviation of the individual measurements from the
mean value must not exceed ±3 mm (max.). Log the
measurements, so that you can compare their accu-
racy at a later point of time.
MAINTENANCE AND SERVICE
MAINTENANCE AND CLEANING
Store and transport the measuring tool only in the sup-
plied protective pouch.
Keep the measuring tool clean at all times.
Do not immerse the measuring tool in water or other
fl uids.
Wipe off debris using a moist and soft cloth. Do not use
any cleaning agents or solvents.
Maintain the reception lens 5 in particular, with the
same care as required for eye glasses or the lens of
a camera.
If the measuring tool should fail despite the care taken
in manufacturing and testing procedures, repair should
be carried out by an authorised after-sales service cen-
tre for SBM Group power tools. Do not open the meas-
uring tool yourself.
