TROUBLESHOOTING
Symptoms: Check points:
No power
- Is the main power switch (# 34, on the back of the unit) switched to "I"?
- Check fuse (#35) - see page 12.
Bright and hazy spots in the picture - Is the top mirror (#3) or the glass over the base mirror (#2) dirty? - see CLEANING page 12.
Low light - Is the lamp worn out or not correctly placed in the socket?
No light - Is the light switched off (LIGHT keys #21)?
- Is the lamp burned out?
- Is the light slot covered?
The left edge of the picture is black / the right
edge of an object isn't illuminated (outside of
the working surface) - Switch off the light with the LIGHT off key (#21) and work with room light.
(This is not a failure of the unit, see page 7 - "Synchronized Lightfield")
No picture on a projector or monitor - If the IMAGE key (#17) is illuminated red on the control panel, then the switchable outputs
are switched off - Switch on with the IMAGE key
- Is the IRIS closed? Press the IRIS bright key (#24)
- Check cable connection and input of monitor/projector!
- Check if the monitor or projector is capable to display the image output by the Visualizer.
If not select a lower output mode or frame rate (see page 5)
- Check if the correct Sync-Mode is selected (see page 10)
Reflections / Glare - The working surface of the Visualizer is reflection free (provided that the material is not
very wavy). If there are reflections in the picture it must be due to room light. Switch it off!
Autoiris does not work - The autoiris function is switched off when using the IRIS keys (#24).
It is switched on again when using the ZOOM keys (#13)
Poor picture quality - When you are using a lower resolution LCD or DLP projector or monitor, it is possible that
this unit can only display the image output by the Visualizer in compressed format. In this
case set the Visualizer to the native resolution of your projector or monitor (see page 5).
- Using a projector: If you are unsure if the bad picture quality is due to your projector or
settings of the Visualizer, connect a CRT-monitor to the Visualizer. If the picture looks good
on the monitor check your projector.
- Check the camera set-ups in the on-screen menu. If you are unsure about the settings
use the "reset" function in the menu or the key combination: RESET (#20) + MENU (#23).
False colors - Adjust the white balance of the Visualizer (see page 13)
-
Adjust the white balance of the your LCD- or DLP-projector (when there's too much blue).
Too much green in the picture - Use either SYNC ON GREEN or SEPARATE SYNC but not both at the same time!
(see page 10).
No stable picture (Sync problems) - Check if the monitor or projector is capable to display the image output by the Visualizer.
If not select a lower output mode or frame rate (see page 5)
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 the picture is much smaller than the light field, check if your monitor of projector
cuts off the image. Check the settings "Height", "Width", "Horizontal centering" and
"Vertical centering" on your monitor or projector. If a very large part of the picture is cut off,
your projector or monitor may only be able to display a part of the Visualizer picture in a
window. (e.g. when the Visualizer is set to SXGA output and the projector can only
display 800x600 pixels). In this case select a lower output format (see page 5).
- If you are sure that the lightfield is still much larger than the recorded area and it is not
due to wrong monitor or projector adjustment, consult your WolfVision dealer. The size of
the lightfield can be adjusted electronically using a special WolfVision service software.
VZ-57: The Laser Center Marker is slightly right
or slightly left of the middle of the pick-up area. - This is not a failure of the unit. It is optically impossible that the Laser Center Marker is
100% in the horizontal middle of the picture with every length of the arm (macro mode on
or off). But it is adjusted to be very close to the middle with every length of the arm.
The size of the lightfield does not change when
zooming in and out - You are in the MACRO mode - press the MACRO key (#18) - see page 8
- You are in the MACRO mode - press the MACRO key (#18) - see page 8
- You are in the MACRO mode - press the MACRO key (#18) - see page 8
- You can change the macro mode from 12x macro to 11x macro in the units menu. The
enlargements are not as big as before but the depth of focus is higher in the 11x macro
mode - see page 14 and on-screen help menu.
It is not possible to pick-up the whole working
surface. The zoom stops at 42 x 33mm
Depth of focus is not as large as usual
Depth of focus in the macro mode in too low for
your application.
The image is flickering slightly - The Visualizer may be set to output 60Hz. Set it to 75Hz in the units menu (see page 14).
Distorted image at the Y/C or Composite output - Switch the output mode in the units menu (see page 14) between PAL and NTSC
Presets can not be stored - The Preset is set to a specific function (see page 9). Set it to "Preset" in the on-screen menu.
