Environmental conditions
l
When the product is transferred from a cold to a significantly warmer environment, water may
condense on some elements inside the scanner. To avoid this, we recommend placing the
scanner in an airtight plastic bag before bringing it from a cold to a significantly warmer
environment. This allows the condensation to form on the bag and not inside the scanner. If
you do not have the possibility to pack the scanner airtight, please wait until observable
condensation water evaporates from the scanner before switching on the laser scanner.
l
For applications requiring the highest degree of accuracy such as reverse engineering and
starting with the scanner at lower temperatures, it is advised to turn the scanner on and warm
it up until the internal temperature stabilizes.
l
If the temperature of the scanner is above or below the specified range, you will get a warning.
Scanning is still possible but the temperature may have impact on the measuring accuracy. If
an upper or lower temperature limit is exceeded, the scanner will automatically shut down to
avoid damages.
l
Strong dust formation, fog, rain or snowfall may result in bad measurements. You should avoid
scanning under these conditions.
l
You should avoid scanning objects against direct sunlight. This may result in limited scan data
in this area.
l
Objects or surfaces may have an increased range noise if they are directly illuminated by bright
sunshine.
l
Highly absorbing or highly reflective surfaces increase the range noise and thus the measuring
inaccuracy. If these surfaces are of importance, you should treat them, for example with
developer or anti-glare-spray.
Starting a scan
If you are in a distance less than the eye safety distance (NOHD), respect the laser safety measures
described in the laser scanner manual and in the appropriate national and regional regulation and
work place safety legislation.
If you are in a distance less than the eye safety distance (NOHD), respect the laser safety measures
described in Laser safety (page 16) and in the appropriate national and regional regulation and work
place safety legislation.
Remember that the scanner is turning and the mirror unit is rotating with high speed. Ensure that
the scanner can move freely and that no objects can touch the mirror unit.
You can start your scan either by clicking on the Start Scan button on the Home screen of the
operating software or by pressing the Start / Stop button on the scanner.
If there is not enough space on the SD memory card, you will be warned and the scanner will refuse
scanning. In this case, please remove scan data from the memory card or insert a new card and try
again.
