Scanning: Ambient Conditions 3.5.1

 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

• 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 mirror or in extreme cases even the interior optics can condense. This may cause measurement errors.

➜ Precaution: Avoid rapid temperature changes and give the instrument time to acclimatise.

Dirt on the rotating mirror-protection glass

 Due to the encapsulated mirror design, the mirror is protected against direct contact. However, dirt on the rotating mirror protection glass such as a layer of dust, condensation or fingerprints may cause considerable measuring errors.
