8. ADJUSTING PICTURE QUALITY (Continued)
ALC Adjustment (Light Metering)
Adjustment of light metering between average and peak can be obtained by adjusting ALC
Potentiometer. The method of ALC adjustment is as follows:-
Take off the ALC cap on the lens cover and turn the ALC potentiometer with a precision
screwdriver until suitable exposure is obtained
Turn clockwise for average metering
Turn anti-clockwise for peak metering
Level Adjustment (Image Signal Level Adjustment)
Image level of video signal can be re-adjusted by timing the level potentiometer when necessary
according to the characteristics of the camera and the light conditions of the objects.
It is normally unnecessary to make sensitivity adjustment since the video signal level is set to an
appropriate value at shipment. The method of re-adjustment, if necessary, is as follows:-
Take off the level cap on the lens cover and turn the level potentiometer with a precision
screwdriver so that the optimum level is obtained.
To get picture lighter turn clockwise in H direction
To get picture darker turn anti-clockwise in L direction
When suitable picture quality has been obtained by adjustment of the camera and lens, then the
monitor can be disconnected and the printer draw returned. Check power is on the printer and
close the printer door
