3-12. CCD White Point Defect Detect Adjustment
Measuring location:
VIDEO OUT
Measuring equipment:
Monitor display
Adjustment method:
1. Shield light with a lens cap to provide dark condition.
2. Set the camera mode, and click the “AUTO” at the WDD on
the adjustment software.
3. After completing this adjustment, it comfirms that white point
can not be seen on the monitor display.

3-10. Iris Level Adjustment
Adjustment location:
S3001, VR301 (CA-3)
Measuring location:
VIDEO OUT
Measuring equipment:
Oscilloscope
Subject:
Gray scale chart
Adjusting method:
1. Set S3001 to the DC type lens side.
2. Attach the DC type automatic iris lens. (Use a VCL-CS8LY
or equivalent as the lens).
3. Display the gray scale chart on full screen.
4. Turn the VR301 to the right so that the white level is maxi-
mum.
5. Turn the VR301 to the left so that the output level is 750
±
10 mVp-p.
3-11. External Sync Phase Adjustment
Adjustment location:
VR201 (CA-2), S3002, VR304 (CA-3)
Measuring location:
VIDEO OUT, VBS IN
Measuring equipment:
Oscilloscope
Adjusting method:
1. Input a video signal to the VBS IN terminal, and then use
this signal to trigger an oscilloscope.
2. Turn VR304 to adjust so that the phase difference between
the leading edge of the horizontal synchronization signals
of the VBS IN and VIDEO OUT waveforms is 0
±
0.2
µ
sec.
3-13. External Sync Adjustment (VBS)
Adjusting method:
1. If the signals are not synchronized, change the sub-carrier
(SC-P1) switches as follows.
Note:
1. The sub-carrier switches let you make broad adjustments
to the sub-carrier phase. If finer adjustments are required,
contact the place of purchase.
2. The type and length of the cable which is connected to the
VBS connector may cause the horizontal synchronization
being out of phase. If this happens, adjust VR304 (H-P: hori-
zontal sync).
