The OADM requires no maintenance apart from keeping the front windows clean. Dust or fingerprints can
impair the sensor function. It is normally sufficient to wipe the windows dry with a clean (!), soft cloth. Alcohol
or soapy water may be used for heavy soiling.

field
No receiving signal (transparent or
highly reflective object) Make sure that the laser spot falls on a diffuse
reflecting surface
The sensor has
incorrect measuring
values Mutual optical interferences
between two or more sensors Make sure that no other light spot is within the
receiving field of the sensor
Strong ambient light. Prevent ambient light with a shield
Semi transparent, transparent or
highly reflective objects Make sure that the laser spot falls on a diffuse
reflecting surface
