4-5. Checking after AdjustmentTo check the values after adjustment, remove the
commander and the commander junction fixture from the
camera. Turn off the camera, then turn it on again before
checking.
4-5-1. Checking SYNC Level Adjustment
Check to see if the measured voltage is within the specified
range.
3Check to see if the AD/-IN value (CN302 2 pin) is
within the specified value range.
4-5-2. Checking Burst Level Adjustment
Check to see if the measured voltage is within the specified
range.
4-5-3. Checking SET UP Adjustment
1Turn OFF the AGC switch on the side panel of the
camera.
2Check to see if the measured voltage is within the
specified value range.
4-5-4. Checking 0 db Adjustment
1Turn OFF the AGC and CCD-IRIS switches on the side
panel of the camera.
2Shoot the all-white pattern and adjust the lens iris so
that the CCD LEVEL is the specified value.
*If there is a point where specified value for step 3 is
satisfied while varying the iris within the specified value
range for step 2, the adjustment is correct.
4-5-5. Checking Auto Iris VS Level
1(Same as 4-5-4 1.)
2(Same as 4-5-4 2.)
3Check to see if the measured voltage is within the
Specified range.
*If there is a point where the specified value for step 3 is
satisfied while varying the lens iris within the specified
value range for step 2, the adjustment is correct.
4-5-6. Checking AGC Adjustment
1Turn OFF the AGC and CCD-IRIS switches on the side
panel of the camera.
2Shoot the all-white pattern and adjust the lens iris so
that the VIDEO-OUT image level is the specified
value.
