Scanning

Ambient Conditions

Highly reflective (polished metal, gloss paint)
•
Highly absorbent (black)
•
• Translucent (clear glass)
☞ Colour, powder or tape these surfaces before scanning if necessary.
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.
If the instrument is brought from a cold environment, for example from stor-
age, 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.
