Technical Data
* The typical measurement uncertainty of +/- 2 mm is
valid for measurements on white, diffusive, reflective
targets up to 5 m at low ambient light and moderate
temperatures. For distances greater than 5m, the
measurement uncertainty could increase additionally
by 0.1 mm/m. In unfavourable conditions (such as
bright sunlight, targets with poor reflectivity, or high or
low temperatures) the measurement uncertainty
could further increase up to +/- 4 mm for distances
below 5m and additionally by roughly 0.15 mm/m for
distances greater than 5 m.

Electromagnetic Compatibility
(EMC)
WARNING
The device conforms to the most stringent
requirements of the relevant standards
and regulations.
However, the possibility of causing inter-
ference in other devices cannot be totally
excluded.
FCC statement (applicable in U.S.)
This equipment has been tested and found
to comply with the limits for a Class B
digital device, pursuant to part 15 of the
FCC Rules. These limits are designed to
provide reasonable protection against
harmful interference in a residential instal-
lation.This equipment generates, uses and
can radiate radio frequency energy and, if
not installed and used in accordance with
the instructions, may cause harmful inter-
ference to radio communications.
However, there is no guarantee that inter-
ference will not occur in a particular instal-
lation. If this equipment does cause
harmful interference to radio or television
reception, which can be determined by
turning the equipment off and on, the user
is encouraged to try to correct the interfer-
ence by one or more of the following
measures:
•Reorient or relocate the receiving
antenna.
•Increase the separation between the
equipment and receiver.
•Connect the equipment into an outlet on
a circuit different from that to which the
receiver is connected.
•Consult the dealer or an experienced
radio/TV technician for help.
Laser classification
The device produces visible laser
beams, which are emitted from the
instrument:
It is a Class 2 laser product in accor-
dance with:
•IEC60825-1 : 2014 „Radiation safety of
laser products“
Laser Class 2 products:
Do not stare into the laser beam or direct it
towards other people unnecessarily. Eye
protection is normally afforded by aversion
responses including the blink reflex.
WARNING
Looking directly into the beam with optical
aids (e.g. binoculars, telescopes) can be
hazardous.
CAUTION
Looking into the laser beam may be
hazardous to the eyes.
