3Set the ND filter (transmission factor: 6.25 %).
4Turn ON the AGC switch on the side panel of the
camera, and turn NORM the TURBO/NORM switch
5Shoot the all-white pattern. Check to see if the
VIDEO-OUT image level is within the specified value
range.
4Check to see if the white bright spot on the vector-
scope converges to meet the specified value.
*If there is a point where the specified value for step 5 is
satisfied while varying the lens iris within the specified
value range for step 2, the adjustment is correct.
Or, if there is a point where the specified value for step
5 is satisfied while varying the VIDEO LEVEL on the
side panel, the adjustment is correct.
4-5-7. Checking WB adjustment (3200Kpreset and data take-in)Checking ATW operation
1Set the WB switch on the camera side panel to the
ATW-PRO position, and turn OFF the AGC and CCD-
IRIS Switches.
2Set the C14 filter.
3Shoot the all-white pattern. Adjust the iris diaphragm
so that the VIDEO-OUT image level is set within the
specified value range.
4-5-8. Checking Color Reproduction
Adjustment
1Turn OFF the AGC and CCD-IRIS switches on the side
panel of the camera.
2Shoot the color bar chart.
3Adjust the iris diaphragm so that the VIDEO-OUT
white image level is set within the specified value
range.
4Check to see if the center of the bright spot of each of
the colors is within the color reproduction range.
*If there is a point where the specified value for step 4 is
satisfied while varying the lens iris within the specified
value range for step 3, the adjustment is correct.
