Practical advice
General advice
The reception lens (14) and the laser beam output (15) must not be covered during the
measuring process.
The measuring tool must not be moved while a measurement is being taken. For this
reason, place the measuring tool against or on a firm surface whenever possible.
Influences on the measuring range
The measuring range depends on the lighting conditions and the reflective properties of
the target surface. For better visibility of the laser beam in bright extraneous light, use
the laser viewing glasses (18) (accessory) and the laser target plate (17) (accessory) or
shade the target area.
Influences on the measurement result
Due to physical effects, the possibility of inaccurate measurements when measuring vari-
ous surfaces cannot be excluded. These include:
– Transparent surfaces (e.g. glass, water)
– Reflective surfaces (e.g. polished metal, glass)
– Porous surfaces (e.g. insulating materials)
– Structured surfaces (e.g. roughcast, natural stone).
If necessary, use the laser target plate (17) (accessory) on these surfaces.
