Optical Self Diagnosis
The device checks its visible range permanently. The status of this optical self diagnosis
(OSD) is shown in the user interface.
OK
Normal state.
Covered
One or both cameras covered, e.g. by a sticker.
Too dark
Illumination is too low for proper function or both cameras are
completely covered and show a black image.
Too bright
This is more hypothetical,
because direct sunlight and reflections from sunlight would not
cause a 'too bright' error.
The device does not stop counting in case of an error. The OSD status could help in trou-
bleshooting issues and is also available in data protocols to validate data.
