WolfVision VZ-9plus 3 User Manual - Handbuch (Seite 10)

Please note that the Visualizer has an optical 16x zoom. The digital 4x zoom increases the overall zoom
range to a 64x zoom. The smallest pickup size on the working surface without digital zoom is 25 x 19mm
(1" x 0.8"). When you zoom in further the digital zoom is automatically activated and the smallest pickup
size is 6 x 4mm (0.23" x 0.16"). However please be aware that when the digital zoom is used, the
resolution of the picture is not as good as before. The default setting displays a message on-screen when
you are in the digital zoom mode.
Still pictures in the memory can also be digitally zoomed.
You can change the behavior of the Visualizer in the digital zoom mode in the on-screen menu (see page
16).
The Visualizer offers the possibility to store the current settings as a Preset and recall them by just pressing
the respective PRESET key (#31) on the remote control.
Preset 1 can be controlled with the PRESET key on the camera head (#47).
For storing a reset adjust y function as required and then PRESET key for 2
seconds . An on-screen message inform you when the Preset is stored.
As mentioned above, when presets are stored all current settings such as zoom, focus, iris etc. are also
stored. Contrary to this, a user also has the opportunity to assign specific functions such as "TEXT",
"LIGHT”, "NEGATIVE", "NEGATIVE/BLUE", "BLACK/WHITE", "FREEZE" etc. to a PRESET key in the on-
screen menu of the Visualizer (see page 16).

Preset Function
Digital Zoom
WolfVision Visualizers are equipped with an auto iris. This means that the brightness of the camera image
adjusts automatically. Using the IRIS keys (#44) the auto iris function is switched off. In this mode the Iris
can be adjusted manually.
When using the ZOOM keys (#37) or ZOOM wheel (#13) the auto iris function is switched on again.
The standard auto iris level can be set brighter or darker in the unit's on-screen menu. When picking up
areas with bright spot, Back Light Compensation can be switched on in the unit‘s on-screen menu - see
page 16 and on-screen help.
Auto Iris / Manual Iris
Text Mode
For improving the readability of text, sketches or x-rays, the text mode can be activated by pressing the
assigned PRESET key
.
This mode enhances the contrast of the picture. Please note that the colors are now darker than usual. To
switch off the text enhancement mode, press the
again. When the text
enhancement mode is in use, the message "TEXT" is permanetly displayed on the built-in LCD monitor.
This should remind the user to switch off the text mode when it is no longer required. It should also prevent
users trying to correct dark colors by opening the iris, resulting in a poorly adjusted picture.

Focusing / Autofocus
Please note that objects with very low contrast (like blank sheet of paper) are difficult to focus. If the
autofocus does not work just move the object slightly.
For special applications the autofocus can also be switched off using the on/off switch (#34 or #49). The
autofocus is also switched off when the manual FOCUS keys (#35 or #48) are used.
