1.3 Initial operation
After connecting the power cord, the
device can be started with the red main
switch. The camera LED will be started. For
visualization of the camera image, at least
a conventional monitor or the imaging
recorder must be connected to the video
output of the device.
The device must be operated exclusively
in environments, which guarantee that
the in-built ventilator supplies the lamp
with sufficient fresh air for cooling. In
case of insufficient cooling, there can be
damage to the LED.
Example
The following is recommended for visualization:
:: Standard studio monitor, type CRT
(best results) 10” to 21”
::
INVIZ image recorder
:: LCD monitors
:: Fast laptop / Notebook via high-value
framegrabber (Status 2006 USB
framegrabber cannot be recommended)
:: Head up display
For storage of image and video, the
following are recommended given the
current state of technology:
:: VHS recorder (adequate quality only in
S-VHS operation)
:: DVD / hard disc recorder
:: Mini DV Camcorder with AV input
:: Fast laptop / notebook via high value
framegrabber (s per status 2006, USB
2.0 framegrabber cannot be
recommended), e.g. Fire Wire / PCMCIA

For avoiding possible damages to the
monitor, it is recommended to operate
the inspection camera or external periphe-
real devices like monitor or video recor-
der via the same main power potential.
This is ensured for all participating users
through the use of a multiplug. In case
very long video cords are used, there can
be disturbing equalizing current via the
shielding of the cable.
The video image of the camera head can
now be captured as so-called Composite
Signal (“video signal” in common parlan-
ce) via the lateral BNC video output
through every conventional televisionwith
Scart/AV input. The S-VHS (Y/C) output lying
thereunder offers a visibly improved quali-
ty in the detail of the image signal and
can be used with accordingly higher value
devices.
In order to use the full image quality of
the high-resolution camera quality, we
recommend that accordingly high resoluti-
on special monitors from a screen size of
10” onwards be used exclusively for
inspection tasks in the material test, which,
also possess an S-VHS input.
All video connection cords to periphereal
devices must exhibit a resistance of 75
Ohm and are characterized by the identi-
fication RG 59. Beside the industrial BNC
connector, the so-called CGA / RCA /
Cinch connectors are widely popular; corre-
sponding adapter and/or adapter cable
can be ordered in the trade.
As a rule, recording device and monitor
are switched in series, for being able to
control the recording results easily. Older
video devices do not terminate the video
line automatically with a 75 Ohm terminating
resistance. This must be placed in the
correct position manually by means of a
switch. You may refer to the instructions
of the respective devices. A wrongly set
or missing terminating resistor and/or
the parallel operation of several termina-
ted users at one output can lead to signifi-
cantly dark or overexposed pictures, it
can lead to colour distortions and can
lead to so-called ghost images in extre-
