4.3.2 FUNCTION TEST
With above settings, the camera will output a good
picture and you can proceed to the fine tuning process.
4.3.3 WHITE BALANCE
Equipment: Color bar chart (3200°K),
Vector scope, Wave form monitor.
Set AGC and White balance selection to Manual side
(short to GND).
Set to auto-shutter off(PWB2, A/M to GND).
Use standard lens (Calibrated ) and set the iris to F=8.
For 5600°K, use blue conversion filter.
Burst level
Confirm that burst level on Vector scope is on the 75 %
line.
4.2 PREPARATION
4.2.1 BACK FOCUS ADJUSTMENT (ONLY FOR
OPTIONAL REQUIREMENT)
Subject: Resolution chart
1. Mount the manual lens (i.e. Cosmicar 25mm,
F=1.4).
2. Open the lens iris completely and set lens focal
length to minimum for the lens used (e.g. 2 ft.).
3. If image is not focused properly, set back focus as
follows.
4. Unscrew the M2x3 hex screw on the Front Panel
until the focus ring is loose.
