3. ADJUSTMENT
3-1. ADJUSTMENT CONDITION
1. Use the viewer for the subject. As for the fixation of the color
mode, shorten TP301 and TP302 (CA-3) with an alligator
clip.
2. Set the trigger signal of oscilloscope to VIDEO OUT, and
apply H sync unless specified.
3. Set each of the S3002 (CA-3) to the all OFF position, S3001
to the DC position and S3003 to the L position.
4. In adjustments without direction to display charts, shield light
with a lens cap to provide dark condition.
5. Connect the video output to a video monitor with an input
impedance of 75 .
6. Ground test point are TP200 (CA-2) 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/ = 0.45).
8. Apply 24 V AC to the 24 V AC terminal on the camera.
(for VCC-4594P)
Apply 12 V DC to the 12 V DC terminal on the camera.
(for VCC-4592P)
