* The distance range can vary depending on the conditions and can
be above or below the specied value. The specied range value is
referring to non-extreme conditions, visibility about 20 km, moder-
ate sunlight, slight heat shimmer.
ISO17123-4 Measure time, typical [s]
Standard measuring 3 mm + 2 ppm 1.1 in Quick mode
1.4 in Standard mode
>200m 5 mm + 3 ppm -
Beam interruptions, severe heat shimmer and moving objects within the beam
path can result in deviations of the specied accuracy and measurement time.
