16. Cleaning and maintenance
NOTE!
Use the below specified methods of maintenance only.
Camera enclosure - all surfaces, except for optical elements of the camera, can be
cleaned with a soft and moist cloth with generally available mild detergents. Do not use
any solvents or cleaning agents that could scratch the enclosure (powder, paste, etc.).
During cleaning, the camera must be turned off.
Due to the applied anti-reflective coating, optical lens are the most sensitive and at the
same time the most expensive part of the camera (the lens is of key importance to radio-
metric capabilities of the infrared system). Therefore it is important to close the protective
lens cover after each use of the camera. Optical surfaces should be cleaned only, when
they are visibly fouled. Do not touch exposed surfaces of optical lens with fingers, be-
cause fouling left with fingerprints can be harmful to coatings and glass of the lens.
Chemical agents must not be used for cleaning the optical viewfinder, and particularly op-
tics and accessories of the camera. Use a clean, dry and soft cloth for cleaning the body
of the viewfinder; for cleaning the lens, use only the supplied lens cleaning cloth.
17. Calibration
In order to ensure the accuracy and reliability of the thermal imaging camera it is recom-
mended to calibrate the instrument once every 12 months.
