Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot
be excluded when measuring on different surfaces.
Included here are:
– Transparent surfaces (e.g., glass, water),
– Reflecting surfaces (e.g., polished metal, glass),
– Porous surfaces (e.g. insulation materials),
– Structured surfaces (e.g., roughcast, natural
stone).
If required, use the laser target plate 9 (accessory) on
these surfaces.
Furthermore, faulty measurements are also possible
when sighting inclined target surfaces.
Also, air layers with varying temperatures or indirect-
ly received reflections can affect the measured value.
Accuracy Check of the Distance Measurement
The accuracy of the measuring tool can be checked as
follows:
– Select a permanently unchangeable measuring
section 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 measurement
should be carried out under favourable conditions,
meaning, the measuring distance must be indoors
and the target surface for the measurement must
be smooth and reflect well.
