Cameras and Lenses
Check that the correct lens is fitted in line with the specification. Set up the lens focus and back focus of the camera. If automatic iris lenses are fitted, adjust the peak/average and level potentiometers. Check that the field of view is as required. This will usually be adjusted using a hand held test monitor. There is also available a hand held focus adjuster. If the camera has to cope with a wide range of light conditions, fit a neutral density filter to set the focus at the maximum lens aperture.
If a zoom lens is fitted, check that the scene remains in focus throughout the zoom range. If the focus changes, it may be necessary to recheck the camera back focus.
