LENS SETUP AND FOCUS PROCEDURES

Video Drive Auto Iris Lens

When a video drive auto iris lens is used, the lens mode selector switch must be set to AIV. Switch the ESC and AGC OFF. Refer to the lens instructions and adjust the lens for the optimum picture (video output level of 1V peak-to-peak). Switch the AGC ON. To focus, fully open the iris by covering the lens with a suitable neutral density (ND*) filter. If the viewed scene is 6.5 feet (2 m) away or farther, set the lens focus to infinity (far). Use the back fo- cus adjustment ring (refer to the Back Focus Adjustment section) and focus on the selected scene. Remove the ND filter and set the lens focus as required.

Direct Drive (DC) Auto Iris Lens

When a direct drive lens is used, the lens mode selector switch must be set to AID. Switch the ESC and AGC OFF. Use an appropriate screwdriver to turn the lens level potentiometer (refer to Figure 1) fully clockwise. Next, slowly adjust the potentiometer counterclockwise until the optimum picture is obtained (video output level of 1V peak-to-peak). Switch the AGC ON. To focus, fully open the iris by covering the lens with a suitable neutral density (ND*) filter. Select the scene to be viewed. If the viewed scene is 6.5 feet (2 m) away or farther, set the lens fo- cus to infinity (far). Use the back focus adjustment ring (refer to the Back Focus Adjustment section) and focus on the selected scene. Remove the ND filter and set the lens focus as required.

Fixed Lens

Set the ESC switch and AGC switch to ON. To focus, set the lens focus to infinity and view an image greater than

6.5feet (2 m) away. Focus the image with the back focus adjustment ring (refer to the Back Focus Adjustment section). Set the lens focus as required.

Manual Iris Lens

Set the ESC switch and AGC switch to ON. To focus, open the iris fully and set the lens focus to infinity. View an image greater than 6.5 feet (2 m) away. Focus the image with the back focus adjustment ring (refer to the Back Focus Adjust- ment section). Adjust the lens focus and set the iris for the best picture quality. The largest aperture gives the best light sensitivity, the smallest aperture the greatest depth of field.

Zoom Lens

Set the lens focus to infinity (far) and fully open the iris by covering the lens with a suitable neutral density (ND*) filter. Zoom out to the widest field of vision and view a distant object. Adjust the back focus adjustment ring until the object is in focus (refer to the Back Focus Adjustment section). Next, zoom fully in and adjust the lens focus until the object is again focused. Repeat these steps until the full zoom range may be viewed with the minimum loss of focus.
