7.1 Measuring accuracy

The measuring accuracy corresponds to the ISO-recommendation ISO/R 1938-1971 with a statistical
confidence level of 95.4 % (i.e. ± twice the standard deviation
typical measuring accuracy relates to average conditions for measuring.

The values are valid at the continuously measurement.
Maximum deviation may occur under unfavorable conditions such as bright sunlight or when
measuring to poorly reflecting or very rough surfaces. Measuring accuracy may deteriorate by
approximately ±0.02 mm/m for distances above 30 m.
The LLB does not compensate changes of atmospheric environment. These changes can influence
the accuracy if measuring long distances (>150 m) under conditions very different from:
•
20 °C ambient temperature
•
60 % relative humidity
•
953 mbar air pressure.
The influences of the atmospheric environment are described in:
