WolfVision VZ-35 - Manual (Page 22)

22
Symptoms: Check points:
The right edge of the picture is black / the right
edge of an object isn't illuminated (using the
Visualizer as a video camera) - Switch off the light with the LIGHT off key (#23) and work with room light.
(This is not a failure of the unit, see page 7 - Lighting)
No monitor picture - Are the switchable outputs (Composite, Y/C or RGBS) switched off?
Switch on with the IMAGE on key (#22)
- Is the IRIS closed? Press the IRIS open key (#20)
- Check cable connection and input of monitor/projector!
Reflections / Glare - See detailled description on page 7.
Poor picture quality on the projection screen
(using the Visualizer together with a video
projector) - This is mostly due to bad adjustment of the video projector. Connect a
TV-monitor to the Visualizer. If the picture quality is good on the monitor
check the adjustment of the video projector.
Autoiris does not work - The autoiris function is switched off when using the IRIS keys (#19,#20).
It is switched on again when using the ZOOM keys (#15,#16)
Bad picture quality - Check the camera set-ups of the Visualizer (see page 13-18)
- Check the set-ups and quality of your monitor or projector.
False colors - Adjust the white balance (see page 13+15)
- NTSC: adjust color phase of monitor or projector
Too much green in the picture
(when using the RGBS output) - Use either SYNC ON GREEN or SEPARATE SYNC but not both at the
same time! (see page 17).
No color (B/W only) - Check the TV standard of the monitor or projector (PAL/Secam/NTSC)
- Check color adjustment of the monitor or projector
- Check the Y/C cable (if there is color when using the composite video
output, the Y/C cable may be defective)
- Check camera settings (D-SUB must be set to Y/C)
No stable picture (Sync problems)
- RGBS-output: Check Sync connection. Use either SYNC ON GREEN or
SEPARATE SYNC (see page 17)
- RGBS: If the sync level is too low, adjust it in the camera menu setup.
- Adjust V-Hold on monitor or HV-frequencies on projector
Vibrations in the picture - Place the Visualizer on a solid table, so that the unit is protected from
movements of people working on that table.
Darker picture on a monitor when connected
with the RGBS output - This is a technical peculiarity of RGB monitors, not a failure of the unit.
- Adjust brightness and contrast of your monitor
Infrared remote control does not work - Change the battery! (see page 11)
- If the unit cannot be controlled with the infrared remote control even from
a close distance and with a new battery it may be due to a wrong frequency
(see page 12).
Color bars appear on the monitor - Press the BARS key of the camera control panel (#12)
The lightfield on the working surface is much
larger than the recorded area. Please note that the lightfield has to be a little bit larger than the recorded
area, otherwise it would not fit in all positions (on the working surface).
However if it is much too big check the following:
- First check if it is possible to adjust your monitor. Many TV-monitors do not
display the whole picture. Some show more of the right side, some more of
the left side etc. Check if there is an UDERSCAN function - with this
function you can display 100% of the Visualizer picture.
- If you are working with a projector (CTR) check the "blanking" of the
projector
- If you are sure that the lightfield is still much larger than the recorded area
and it is not due to a wrong adjustment of your monitor of video projector,
consult your Wolfvision dealer. The size of the lightfield can be adjusted
electronically using a special Wolfvision service software.
