Note
For the CM1950, two different variants of the connection piece inside the instrument and the UVCLamp are available. The user needs to check which variant is built-in in the instrument prior to the
exchange of the UVC-Lamp with a new one.
The procedure to exchange the UVC-Lamp is similar with both variants.
