•
If the temperature is outside the specified range, an error message is
displayed. Scanning is still possible, but the measuring accuracy is no
longer within specification.
Precaution: Warm up / cool down the instrument.
•
To avoid damages of the electronics, the instrument switches off when
the upper temperature limit is exceeded.
Precaution: Cool down the instrument in a cold place.
•
If the instrument is brought from a cold environment (e.g., from storage)
into a warm and humid environment, the glass window at the mirror or in
extreme case even the interior optics can fog up. This causes measure-
ment errors.
Precaution: Avoid large temperature differences; give the instrument
time to acclimate.
Soiling at the glass pane of the mirror, such as a layer of dust, condensed
water or fingerprints, causes considerable measuring errors.
Before initiating the scanning process check if there is enough space on the
internal flash disk (30 – 60 GB per day, depending on your planning).
