8. ADJUSTMENT
1. Supply power to the camera. The power indicator
⑪
will light.
2. Flickering of lighting may interfere with the view when the camera is used in the room in the area with
power frequency of 60 Hz. To view the flickering-free picture, shift the flickering-reduction switch of the
mode switch
⑥
to "1/120" position.
Note
Placing the flickering-reduction switch in the "1/120" position makes the sensitivity lower than in the "(1/50)"
position. Use the "(1/50)" position when the flickering does not interfere with the view or when the camera
is used in dark locations.
3. Connect the video output terminal
⑩
to the monitor so that the picture may be displayed on the monitor.
4. Adjust the camera angle viewing the monitor screen.
5. Adjust the lens for the best possible picture reproduction.
●
When using the DC input type lens, adjust the sensitivity with the iris control
⑦
.
●
When using the VIDEO input type lens, adjust the sensitivity with the ALC or LEVEL control of the lens.
Notes
●
Because the iris control is set to the optimum position by the factory, avoid handling it. Rotating the
control more than required could downgrade the image quality or result in camera malfunction. When
readjusting the camera, first set the AGC switch of the mode switch to "OFF" position, then adjust the
iris control for the best possible picture reproduction. After adjustment completion, cover the lens front
with the hand and remove it from the lens a few seconds later. If you find the lens iris is functioning
correctly, shift the AGC switch back to "(AGC)" position.
●
The object that was brought into focus in bright locations could be out of focus in dark conditions. In
such cases, use a commercial ND filter for focus adjustment.
●
When the distance to an object is shorter than the lens' shortest focusing distance or when a zoom lens
is used, if the object is out of focus, adjust the camera as instructed below (back focal length
adjustment):
5-1. Attach a lens to the camera.
5-2. Loosen the back focal length
adjustment ring fixing screw
①
.
5-3. Rotating the back focal length
adjustment ring
②
, adjust it to the
optimum position.
5-4. Retighten the back focal length
adjustment ring fixing screw.
6. Set the synchronizing method using the synchronization selector switch of the mode switch
⑥
.
One of the following methods can be selected: internal locking (switch position: "INT"), line locking ("LL"
position), and vertical signal external locking ("INT" position). In this setting, when the camera is connected
to other equipment capable of using vertical signal external locking, the method is automatically switched
from internal locking to vertical signal external locking. When using the line locking method, set the
synchronization switch to "LL" position.
Note
You cannot use the line locking method in the area where the power frequency is 60 Hz.
7. Using the vertical phase control
⑧
, synchronize the camera. (This adjustment is required only for line
locking mode.) When using multiple line-locked cameras ("LL" position) and switching camera outputs by
means of a sequential switcher, the pictures may be distorted depending on the distance to the power
source or camera installation conditions. In such cases, turn the vertical phase control to avoid the picture
distortion.
