1. In the case where a hand reader is exposed to direct sunlight
for a short period of time will this affect the calibration scores (R C and E
This will affect the scores. You should not go into and
recalibrate the reader during sun exposed times as it will throw the
calibration numbers off
2. Will it permanently damage the camera / affect the calibration?
damage will be done to the camera; the images will just be over exposed. Just
like taking pictures with your own camera pointing it at the sun.
3. Would you expect the calibration reading revert back to normal once the unit is out of the sun?
as long as the HandReader was not “recalibrated during that time”.
4. Can you explain what the “calibration” menu option does?
The “calibration” menu will give you the calibration numbers of
the camera the last time the camera was initialized. The camera is initialized
only during a power cycle (boot) or through the “Recalibrate” option under the
So basically this is what is happening, reflective surface
(reflexite…the surface with the diamond pattern on it) is the same type of
material that you see in running shoes/trackies. It is super reflective when
the headlights from automobiles shine on a runner’s shoes at night. The same
phenomenon happens when direct sunlight shines on the platen surface during the
daylight. The platen becomes highly reflective and it overexposes the camera.
We suggest resetting the camera via a power cycle or
“recalibrate” when the HandReader is not in direct sunlight. Then block the
HandReader from the direct sunlight when using it.
