*Measuring Accuracy depends on the current conditions:
• Under favorable conditions (good target surface, low background illumination, and room temperature), up to 10 m. The
measurement error can increase by ± 0.1 mm/m for distances over 10 m
• In unfavorable conditions (poor target surface, high background illumination, operating temperatures at the Upper or lower
end of the temperature range), the measurement range may be reduced and the accuracy can increase to ± 6 mm for
distances under 10 m. Beyond 10 m the measurement error can increase by ±0.25 mm/m.
**Resolution is the finest measurement you can see. In mm, that is 1 mm.
