A) The working range increases depending on how well the laser light is reflected
from the surface of the target (scattered, not reflective) and with increased brightness
of the laser point to the ambient light intensity (interior spaces, twilight). In unfavorable
conditions, e.g., with extreme interior illumination or a badly reflecting surface, the
measuring range may be limited.
B) In unfavorable conditions, e.g., with extreme interior illumination, badly reflecting
surface or the room temperature deviating heavily from 77°F (25°C), the maximum
deviation can be up to ±7 mm per 15 m. In favorable conditions, a deviation influence
of ±0.05 mm/m must be taken into account.
The measuring tool can be clearly identified with the serial number 5 on the type
plate.
