3. ADJUSTMENT
3-1. ADJUSTMENT CONDITION
1. Use the 5,100K viewer for the subject.
2. Set the trigger signal of oscilloscope to VIDEO OUT, and
apply H sync unless specified.
3. Set S3002 to the “all OFF”position and S3001 to the “DC”
position.
4. In adjustments without direction to display charts, shield light
with a lens cap to provide dark condition. The amount of
light is to be stable.
5. Connect the video output to a video monitor with an input
impedance of 75 Ω.
6. Ground test point are TP103 (CA-1) and TP401 (CA-4).
7. Set the distance from the subject to about 60 cm and adjust
the camera position so that the picture frame size becomes
as shown below when performing the adjustment with the
gray scale chart (ITE gray scale chart/ γ = 0.45).
8. Apply 24 V AC to the 24 V AC terminal on the camera.
3-2. PREPARATION
1. Install the adjustment software (VHJ-0133) in a computer
running the Windows operating system.
2. Use the adjustment tool (VHJ-0127) to connect the camera
to be adjusted to the serial port of the computer, and then
turn on the power for the computer and the camera.

3-9. Hue and Chroma Adjustment
Adjustment location: S3002-8 (CA-3), computer screen
Measuring location: VIDEO OUT
Measuring equipment: Oscilloscope, Vectorscope
Subject: Color bar chart
1. Display the grayscale chart on full screen.
2. Gradually move the lens aperture from the CLOSE to OPEN
side, and secure the aperture at the point where the AGC
starts to drop from the MAX setting.
3. Shield light with a lens cap, and then remove it.
4. Use the computer’s mouse to adjust each of the R GAIN, B
GAIN, R HUE and B HUE until the luminescent spot repre-
senting red is aligned with the [R] position on the vectorscope
and the luminescent spot representing yellow is aligned with
the [YL] position on the vectorscope.
5. Set the S3002 (white balance switch) to the “ATW”(OFF)
position.

Adjustment location: CT232 (CA-2)
Measuring location: TP232 (CA-2)
Measuring equipment: Digital voltmeter
Subject: No designation
Adjusting method:
1. Adjust with CT232 to 8.0 ±0.2 Vp-p.
3-7. AGC Level ADJUSTMENT
Adjustment location: Computer screen
Measuring location: VIDEO OUT
Measuring equipment: Oscilloscope
Subject: Gray scale chart
Adjusting method:
1. Click the adjustment software installed from the personal
computer, and the adjustment window will be displayed.
2. Display the grayscale chart on full screen.
3. Gradually move the lens aperture from the CLOSE side to
the OPEN side, and secure the aperture at the point where
the AGC starts to drop from the MAX setting.
4. Use the computer’s mouse to adjust the AGC in the adjust-
ment window so that the video out terminal is 750 ±10 mVp-p.
3-8. White Balance Adjustment
Adjustment location: S3002-8, VR302, VR303 (CA-3)
Measuring location: VIDEO OUT
Measuring equipment: Oscilloscope, Vectorscope
Subject: Color bar chart
Adjusting method:
1. Set the S3002 (white balance swtich) to the “MANU”(ON)
position.
2. Display the grayscale chart on full screen.
3. Gradually move the lens aperture from the CLOSE side to
the OPEN side, and secure the aperture at the point where
the AGC starts to drop from the MAX setting.
4. Adjust VR302 and VR303 so that the luminescent spot rep-
resenting white is overlapping with the crosshair mark in
the center of the vectorscope.
