4-5. Checking after Adjustment
To 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.
