The safety instructions and the user manual
should be read through carefully before the
product is used for the first time.
The person responsible for the product must
ensure that all users understand these directions
and adhere to them.
Technical data
* favourable conditions are: white and diffuse reflecting target
(white painted wall), low background illumination and
moderate temperatures.
** unfavourable conditions are: targets with lower or higher
reflectivity or high background illumination or temperatures at
the upper or lower end of the specified temperature range.
*** Tolerances apply from 0.2 m to 5 m with a confidence
level of 95%.
With favourable conditions the tolerance may deteriorate by
0.1 mm/m for distances above 5 m.
With unfavourable conditions the tolerance may deteriorate
by 0.15 mm/m for distances above 5 m.
