HOW THE VISUALIZER WORKS
b
a
A light projector (b) inside the Wolfvision Visualizer projects
the light via a mirror inside the unit and a mirror on the reflector
head onto the working surface. The video camera (a) inside the
unit scans the picture where the light falls.
The optics of the camera and the light projector are synchronized.
This means that when the size of recording area is increased or
decreased with the ZOOM-keys (#15,#16), the size of the
illuminated area on the working surface is also increased or
decreased.
Thus the illuminated area on the working surface always indicates
where the camera scans the picture. (In fact, the scanned area is
fractionally smaller than the light field.)
1. Press the release
button 2. Pull arm
upwards
BASIC PREPARATIONS
1. Press the release for the arm (#11) and simultaneously pull the arm upward. Make sure that the arm is
extended to its full length.
2. Connect the power cable to the unit (#36) and plug it in.
3. Connect a control monitor (if required) to the Preview video output (#31).
4. Connect a large viewing monitor or a video projector to the Composite video output (#32), the Y/C output
(#37) or the RGBS output (#40). These outputs can be switched on and off with the IMAGE keys (#21,#22)
of the control panel.
For live image projection we highly reccomend using the Y/C output (#37). The picture quality (especially
the resolution) is much better than with the Composite video output (#32).
5. Turn the main power switch (#34, on the back of the unit) to "I". The red power indicator (#29) on the
control panel indicates that power is supplied.
6. Press the POWER on key (#28) on the control panel. The Visualizer now runs the "factory setup"
(=automatic focusing of an A5 format on the working surface) during which the green LED light (#30)
is flashing. As soon as the green LED light stays illuminated you can start working with the Visualizer.

WORKING ON THE WORKING SURFACE
1. Place your subject material on the working surface. For background use either the white side or the black
side of the working plate. For some objects the best presentation can be made with colored background.
2. Tilt the reflector head (#10) so that the object is illuminated.
TV-Monitor Video projector
DO NOT TOUCH THE MIRROR,
AS FINGERPRINTS CAUSE
BRIGHT AND HAZY SPOTS
ON THE PICTURE ! ALWAYS
KEEP THE MIRROR CLEAN !
CAUTION: SENSITIVE FRONT
COATED MIRROR!
3. Select the enlargement required with the ZOOM keys (#15,#16) on the control panel or the
infrared remote control.
4. Adjust the sharpness with the FOCUS keys (#17,#18) on the control panel or the infrared remote control.
For showing 3-dimensional objects with the Wolfvision-Visualizer, just place them on the working surface
and adjust ZOOM and FOCUS (as mentioned). Due to a special Wolfvision lens the object can be up to 9.7"
(25 cm) in height. If the object is to big for the working surface or if you want to show it from the side just
place it behind or in front of the unit and tilt the reflector head.
WORKING OUTSIDE THE WORKING SURFACE
In this way it is also possible to make recordings
of subjects in the room or surrounding area, as
with a video camera by just tilting the reflector
head.
Due to the great focal range it is possible to
show details even from a great distance to
the unit.
If you want to record people you should turn off the light with the LIGHT off key (#23), so that they are not
dazzled.
AUTOIRIS / MANUAL IRIS
The Wolfvision Visualizer is equipped with autoiris. That means that the brightness of the camera image adjusts
automatically. Using the IRIS keys (#19,#20) on the control panel or the remote control the autoiris function is
switched off. In this mode the Iris can be adjusted manually.
When using the ZOOM keys (#15,#16) on the control panel or the remote control the autoiris function is
switched on again 6
REFLECTIONS / GLARE IMPORTANT
Reflections can appear only in the bottom half of the working surface, where the light is reflected directly into the
camera. In this case, move the object upwards and tilt the reflector head slightly.
If this is not possbile (e.g. with very big objects), pull the working plate to the front of the unit (as shown below)
and tilt the reflector head accordingly. As the working plate is magnetic, it will stick to the unit.
Reflection: No reflection: No reflection:

Please make sure that reflections are not caused by room light !
LIGHTING
The lighting system is fixed for working on the working surface. Because of the oblique mounting of the
camera and the light projector of the Visualizer the light-field shifts to the left when the distance between the
Visualizer and the scanned object is increased. This means that the light field no longer exactly shows the
recorded area. The edges of the light field may also be unsharp. In this case switch off the Visualizers light
with the LIGHT off key (#23) and work with room light.
PRESET FUNCTION
PRESET
21
The Wolfvision Visualizer VZ-15 offers the possibility of programming two presets for the functions Zoom,
Focus, Iris, Light and Image. They can be recalled with the PRESET 1 (#25) and PRESET 2 (#26) key.
This function is very useful for example if a user requires one preset for papers on the working surface and
one preset for an object placed in front of the unit. During his presentation the user just has to press the
PRESET 1 or PRESET 2 key when he changes from one object to the other.
While the VZ-15 is adjusting the preset position the green LED light (#28) is flashing.
For programming a preset just adjust Zoom, Focus, Iris, Light and Image as required and simultaneously
press the PRESET 1 or the PRESET 2 key together with the Image on key (#22)).
PLEASE NOTE: Always press the Image on key before the PRESET key!

SWITCHABLE OUTPUTS
IMAGE
off on
The Composite video output (#32) and the Y/C output (#37) of the Visualizer are switchable. Use the IMAGE
keys (#21,#22) on the control panel or the remote control to switch the signal supplied from these outputs on
and off.
Independently a video signal is always supplied to the Preview video output (#31). This output can be used for
a control monitor. A constant sync signal is supplied to all switchable outputs (even in the image off mode)
eliminating monitor image distortions when switching.
READ-IN DEVICE FOR COMPUTERS
The Wolfvision Visualizer is perfectly suited for working as
a 3-D scanner for computers equipped with a Grabber Card.
A Grabber Card can be used to digitize a video signal, in order
to store and process single pictures on a computer.
Therefore just connect the Composite video output
(#32) or the Y/C output (#37) of the Visualizer to the
according input of your computers Grabber Card.
CONNECTING A NUMBER OF MONITORS

Connect a control monitor to the Preview video output (#31) of the Wolfvision Visualizer. Connect
additional monitors to the Composite video output (#32) or the Y/C output (#37) of the Visualizer by
looping them through the inputs and outputs of each monitor (as shown above).
In this way a number of monitors can be connected. However if the signal is looped through a lot of monitors
a video signal amplifier should be used in order to achieve equivalent picture quality on all monitors. The
number of monitors throught which the signal can be looped without a signal amplifier depends on the
type of monitor and on the cable lenght.

OPTIONAL LIGHTBOXES (Bottom light)
Switch off the light of the Visualizer with the Light off key (#23) and switch on the light of the lightbox.
Optional lightboxes are available from Wolfvisionin 3 different sizes.
These lightboxes improve the quality of transparencies, X-rays and slides.
While working with one of Wolfvisions optional
lightboxes, the light of the Visualizer has to be
switched off - in order to prevent reflections !!!
The Wolfvision Visualizer can also be used for image capture with a video printer. In this manner single
pictures of papers and objects can be made quickly. The lighting and focus problems are eliminated by the
Visualizers superb light and scan system. Just connect the Composite video output (#32) or the Y/C output
(#37) of the Visualizer to the according video input of the video printer.
Connect a control monitor to the video output of the video printer and (if required) a second control
monitor to the Preview video output (#31) of the Visualizer.

A video recorder can be connected to the Wolfvision
Visualizer, so that recordings on video tape can be made.
Simply connect the Composite video output (#32) or the
Y/C output (#37) of the Visualizer to the according input
of your video recorder. When using a S-VHS or Hi-8
video recorder use the Y/C output in order to archive the
best picture quality
Connect a control monitor to the output of the video recorder
SWITCHING TO PLAYBACK OF A VIDEO RECORDER
If you want to mix your presentation with the Wolfvision Visualizer with playback of a video tape, connect the
Visualizer, the video recorder and the monitor (or video projector) as follows:
Connect the Composite video output (#32) or the Y/C output (#37) of the Visualizer to the according
input of the video recorder. Connect the video or Y/C output of the video recorder with the audiences
monitor or video projector.
Adjust the video recorder so that the picture of the Visualizer will be shown. When the video recorder
is switched to play the Visualizers picture will be interrupted by the picture of the video recorder.
Switch the video recorder to stop and the picture of the Visualizer will reappear on the monitor or
video projector.

SCANNING SLIDES
Visualizer
Slide projector
The Wolfvision Visualizer together with one or more
slide projectors allows easy scanning of individual slides
or even whole slide shows (with cross fading).
Just project the slides onto a screen (or another white
surface), switch off the Visualizers light with theLIGHT
off key (#23) and tilt the reflector head to scan the slides
(as shown on the left). In this way it is also possible to
zoom in on details in a slide
LAMP CHANGER
The Wolfvision Visualizer is fitted with a lamp changer.
If one lamp fails, there is no need to replace it immediately.
Just turn the switch of the lamp changer (#8) on the front
side of the machine to the locked position.
The spare lamp is now employed.
Thus there is no need to exchange a lamp during a presentation. The red light above the lamp changer switch
illuminates to indicate that the spare lamp (=the left lamp) is employed.
This acts as a reminder to exchange the other lamp (=the right lamp) for a new one when next convenient.
EXCHANGING LAMPS
