3. ADJUSTMENT
3-1. ADJUSTMENT PREPARATION
1. Set the ITE gray scale chart II(
=0.45) to the viewer.
2. Set the angle of adjustment control (VR) before starting
adjustment at the center or temporary adjustment (nearly
adjusted) unless specified.
3. Set the trigger signal of oscilloscope to VIDEO OUT, and
apply H sync unless specified.
4. Set the operating condition of the camera (switch settings
inside the side panel) as follows in adjusting unless speci-
fied.
E.l./BLC switch (SW402):"OFF" position
Auto iris switch (SW401):"DC" position
5. The VIDEO OUT connector connect to a video monitor ter-
minated in 75
input impedance.
3-2. Power Supply Voltage Adjustment
Adjustment location: VR501 (CA-5)
Measuring location: TP502 (CA-5)
Measuring equipment: Digital voltmeter
Subject: No designation
Adjusting method:
1. Adjust with VR501 to 5.00
± 0.05 V DC.
3-3. Oscillation Control Voltage Adjustment
Adjustment location: CT301 (CA-3)
Measuring location: TP301 (CA-3)
Measuring equipment: Digital voltmeter, Standard signal
generator (for external sync)
Subject: No designation
Adjusting method:
1. Input the standard signal for external sync to CN206.
2. Adjust with CT301 to 3.00
± 0.05 V.
3-4. SUB Voltage Adjustment
Adjustment location: VR201 (CA-2)
Measuring location: TP102 (CA-1)
Measuring equipment: Digital voltmeter
Subject: No designation
Adjusting method:
1. Read SUB voltage from the abbreviation described on the
side A of CA-1 board.
2. Adjust with VR201 to the adjustment value.
Note:
Note that the adjustment value depends on CCD imager.
When installing a new CCD, read the abbreviation described
on the rear side of CCD and write it to the board.
3-5. AGC LEVEL ADJUSTMENT
Adjustment location: VR203 (CA-2)
Measuring location: TP202 (CA-2), VIDEO OUT
Measuring equipment: Oscilloscope
Subject: Gray scale chart
Adjusting method:
1. Adjust the lens aperture so that the waveform level of TP202
is 400
± 50 mVp-p.
2. Adjust with VR203 so that the waveform level is 800
± 10
mVp-p during video output.
