Adjustment Of Back Focus; Adjustment Of Es/Dc- Lenses - videotronic IX-1000AL/IP Mounting And Operating Instructions

Adjustment of Back Focus

This adjustment should only be carried out, if the lens cannot be focused properly
using the lens focus ring. For such a case proceed as follows:
1 Loosen the Allan head screw with the attached
Allan head key. For large distances, turn the
focus ring of the lens almost (0.5 cm) to the
"endless" limit position. If you need to focus an
object near the camera, turn the focus ring of
the lens to a position 1cm before the "near"
limit position.
2 Use the back focus adjustment screw to adjust the distance between lens and CCD
chip until the picture is in focus. Then fix the Allan head screw using the Allan head
key.
3 Finally, focus the picture using the lens focus ring.
Adjustment of ES-Lenses
To adjust a lens with automatic iris (video driven) to the camera, please proceed as
follows:
1. Turn the level potentiometer (position: ES lenses at the lens) to the max. position
H (turn right). The monitor picture then appears to be too bright.
2. Slowly turn the level potentiometer back until the monitor picture appears to be
perfect and is not too bright anymore. Then turn the potentiometer back to the
right (in direction "H") just a little bit.
3. Check the lens performance by using the camera under different and/or changing
light conditions.
