Ambient Conditions 5.4.2

Unfavourable surfaces for scanning

• Highly reflective (polished metal, gloss paint)
• Highly absorbent (black)
• Translucent (clear glass)
☞ Colour, powder or tape these surfaces before scanning if necessary.

Unfavourable weather conditions for scanning

• If the laser shield is exposed to rain, snow or fog it is not possible to scan. To scan in these conditions, position the scanner, for example, under a roof.
• Be aware, that rain, snow or fog may adversely affect measurement quality. Always use care when scanning in these conditions.
• Surfaces that are directly illuminated by the sun cause an increased range noise and therefore a larger measurement uncertainty.
• If some objects are scanned against the sunlight or a bright spotlight, the optical receiver of the instrument can be dazzled so heavily that in this area no measured data is recorded.

Temperature changes during scanning

If the instrument is brought from a cold environment, for example from storage, into a warm and humid environment, the interior optics can condense. This may cause measurement errors.
☞ Avoid rapid temperature changes and give the instrument 15 to 20 minutes time to acclimatise.
