viZaar INVIZ BIG User manual

www.vizaar.com
The device identification “INVIZ” stands
for a series of latest inspection cameras,
which are constructed strictly according
to the instructions of the users.
The video endoscope at hand,
”INVIZ BIG”, is currently the simplest and
at the same time most hard wearing
camera technology for the inspection and
documentation of weld seams and pipe
inner walls in the 30 mm – 300 mm
category. Expect high resolution, impres-
sive colours, highest light sensitivity, full
image, digital image and video memory
as well as a smart text generator option.
irst models of the INVIZ BIG series and
previous are in the market since about 10
years and have been proved to be one of
the most ‘ruggedized’ inspection cameras
in the world. The percentage rate of
failure during the first two years of
operation is less than 5% - not reached
through any other RVI video - equipment
in today’s market place.
By continually and consistently not
including the electrical conductors of the
KEVLAR – reinforced main cable inside
one epoxy-glass fibre pushing pole, the
system keeps difficult flexibillity of tur-
ning multiple corners and bends without
breaking the main camera supply.
The immense amount of options and
custom made accessories will allow the
operator to reach any point of the
application:
:: Simple rotating and maneuvering of the
probe with attached NEW side view optics.
:: Waterproofness up to 50 meter.
:: Longterm-tested durability of the entire
probe through high wall thickness of
the probe.
:: Extremely light sensitive 40mm camera
head, interchangeable with 29mm
standard head.
:: Manoeuverability through many pipe
bends. A widest range of pushing- and
centering tools are supporting the
operator to accomplish his task.
:: Easy focusing of the optics within a
wide range of applications.
:: New several hours lasting
battery-operation option.
In order to obtain the economic advantages
of your endoscope even in the long run,
you ought to read and follow the following
advice, tips and warnings carefully. The
observance of these instructions serve
the purpose of your own safety as well as

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. or
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
:: ast laptop / Notebook via high-value
framegrabber (Status 2006 USB
framegrabber cannot be recommended)
:: Head up display
or 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
:: ast laptop / notebook via high value

or 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-

me cases.
However, the S-VHS output (if available),
the composite output and the LCD
tableau can be operated simultaneously.
The result and the correct interpretation
of an inspection are dependent to a high
degree on the selection of adequate
sighting and documentation medium a too
low resolution, like in case of normal TV
sets, cheap LCD head-up displays or
standard VHS recorders as well as a
faulty colour settings as a rule lead to the
missing of small material errors like e.g.
tears. The same can occur with so-called
digital systems, which partly exhibit
significant detail errors through data
compression or falsify the finest pixels of
the camera during digitalization. The
manufacturer or your dealer will gladly
advise you.
Avoid visual inspections under the
influence of sunlight on the screen.
The connection of any kind of power
supply units at the video outputs can
destroy your video endoscope.
BNC connectors and cables are widely
popular in all industrialized countries
with the most diverse signals and voltage
ranges – before start-up, confirm the
compatibility with your device by
consulting an expert.
Always consider the videosignal-norm of
your INVIZ system (PAL or NTSC), which
should comply to the video standard of
your country. Only NTSC or PAL monitors
/ VCR’s will allow to correctly operate
with your INVIZ scope. The INVIZ LCD
image
recorder will allow to run on NTSC and
PAL through it’s integrated auto-detect
function.

1.4 urther functions of the basic device
With the delivery of an INVIZ system
without imaging recorder, there is a
remote control serially delivered for the
manual control of light emission
strength, or the revolving speed of the
motorized side view mirrors. The remote
control is connected to the the basic devi-
ce by means of the enclosed cord, while
the device is in off mode.
Manual light intensity adjustment
In most of the cases, it is sufficient to
leave the light emission at maximum setting,
since the automatic exposure time con-
trol of the camera (“shutter”) ensures an
optimally exposed picture. In case of spe-
cial applications, like e.g. polished metal sur-
faces, a manual intervention and/or
reduction of the light emission output
becomes necessary.
Motorised regulator “Speed”
All necessary information pertaining to
this can be found in the special section of
instructions manual option +motorized
head’.
Operating hours counter
The operating hours counter cannot be
reseted to zero. Its gives you an indication
of the progressive ageing of the probe.
Through the operating hours counter, you
shall obtain objective values for a realistic
estimate of the economic success of your
inspection work with the system.
PS2 connection socket in the control device
To the extent that the optional text generator
is integrated, the mini keyboard included
with the delivery or another keyboard can
be connected here with PS2 interface.
Alternatively, there is another interface
available in the optional imaging recorder;
but only one of the two connection points
can be occupied for trouble-free operation.
Reel brake
or transport, the reel brake ought to be
pulled carefully, in order to prevent an
unintentional rolling away of the endosco-
pe. Pulling it too hard can damage the
reel axis or the brake itself. or optimum
work, the brake can be pulled slightly or
completely during operation.
Mount for the accessory pouch
The accessory pouch can be simply hung
from the two mounting points and for
local transport, it ought to be fitted with
everything which would be needed for the
next inspection (centering tools, side view
optics, cable etc.). Remove the pouch
before storage in the case and pack
separately.
astening axis for the
variable mounting arm
At this point, the “magic arm” for
fastening the LCD imaging recorder can
ideally be fastened securely. Watch out,
since during a too great deviation of
theadjustable centre of gravity, it is
possible that the entire unit topples and
the device is damaged.

3.1 Option push poles and pushing rods
The inspection push camera INVIZ big
usually can’t be operated within tubes
and pipes when not employing 1,5 meter
push poles with connector or endless
push rods stored on a reel.
The epoxy – fibre poles will allow the
operator to push the camera head to
most of the regions of interest of an indu-
strial device without opening it.
Even the poles and rods will provide
excellent handling advantage during the
inspection, a few precautions must be
observed to guarantee working safety and
keep the device / facillity undamaged.
Push poles and rods are hard-wearing, however will
not withstand any pushing or pulling force. The epoxy
fibre material will break when bended too much. The
allowed maximum bending depends on the design
(stiff , medium , soft ). Epoxy fibre poles are aging
rapidly through high temperatures, chemicals, sol-
vents and frequent usage. The older they are, the
more they have to be exchanged by new material.
viZaar rejects any damage compensation in the descri-
bed case of damage. In case of doubt, please send in
the pushing-aid material for evaluation to the
viZaar service.
10mm stainless steel pole connecting clutches are
especially glued onto the fibre epxoxy material, and
can be pulled-off when mistreated or worn out. Pulled
off / damaged connectors or clutches will cause
tremendous trouble to the facility, when camera head
and other poles may left in a pipe after a 90° bend.
Always check the pole connectors before employing
them to the camera. viZaar rejects any damage
compensation in the described case of damage.
In case of doubt, please send in the pushing-aid
material for evaluation to the viZaar service.
Always confirm when using the 10mm stainless steel
pole connectors, that the clutches are truly locked,
liked described in the below pictures. Open connectors
will cause the same impact as broken / defective
connectors to the object of inspection.
Damaged epoxy – fibre material can cause heavy injury
to your hand, when the PE- outside coating is worn or
damaged!
When using endless push poles stored on a reel be
aware of unexpected force trying to unwind the reel
itself when just opening the reel-break. The rod will
unwind itself in a fast and powerful way, causing injury
to people or damage to the facility!
Even without breaking, the employment of push poles
can disable you to retrieve the camera – head with the
poles from the inspected piping. viZaar rejects any
damage compensation in this case. Employing epoxy
fibre poles and rods is an issue of experience and
training. In case of doubt, please ask viZaar for further
training or technical assistance. Never push the
probe / fibre epoxy pole into the pipe applying high
force, especially through 90° bends!

Employing the poles or rods extremely
depends on the experience of the
operator. The different flexibility of the
rods / poles may be used depending on
the application length and number of
bends. Rods and poles can be combined,
also poles of different flexibillity may be
combined to reach the area of interest. If
the probe or camera head needs to be
rotated, 1,5 meter poles need to be used
instead of the reel.
The poles / rod can be connected to the
camera head or to the centering tool.

3.2 Option centering tools and trollies
Centering tools are necessary to perform
inspections with the INVIZ big in larger
tubes and pipes, nevertheless, a side view
or a straight view is employed. Centering
tools prevent the probe from lying on the
tube/pipe-sole, creating diffculties because
of unacceptable illumination and focusing
situations. Also centering tools prevent
the probe optics to get dirty through
debris in the empty pipe.
or good inspection results, always try to
attach a corresponding centering tool to
each tube diameter.
Two different centering tools technics are
available: ‘Sliding’ centering discs and
brushes for small diameters and larger
centering trollies with wheels reducing
friction. Pushing aids like epoxy fibre
rods or poles are attached to the bigger
trollies or directly to the probe when
using smaller discs only.

When choosing a centering
tool always consider
obstacles, big weldings,
damaged (oval) pipes, dirt
etc. which decreases the
nominal inner pipe diame-
ter. Ignoring the rule to
choose centering tools at a
maximum of 75% - 85% of
the inner tube diameter may
end into the impact of the
probe get stuck inside the
inspection application.
Always assure all
components screws of the
centering tools are perfectly
tightened to not get lost
inside the application.
Heavy centering tools can
cause damage to delicate
tube surfaces.
