7.3 Replacing the lens
Only replace the lenses in dry and low-dust conditions. When the lens is removed, the degree of
protection of the system is no longer guaranteed!
7.3.1 Bayonet lens interface
Position the VarioCAM ® HD head on a solid, level underground so that the lens is directed towards you.
Rotate the lens on the thermography system counterclockwise as far as it will go and/or until the two red
dots are aligned. Then, remove the lens to the front.
In order to attach the lens, the red marking spots on lens and camera must be aligned. In this position,
the lens must be pressed slightly against the camera corpus and turned clockwise until the red dot of the
lens is aligned with the white dot of the camera.
7.3.2 Screw thread lens interface
Regarding the VarioCAM ® HD head version with alternative screw thread lens interface*, the lenses are
replaced in analogy to the bayonet: The lens is removed by turning it counterclockwise and the lens is
attached by turning it clockwise.
