2.1 Tips for your operations with the
INVIZ
®
MATRIX
2.1.1 After the initial start-up
After the initial startup of the INVIZ
®
system, the
following points may be noticed by you:
::
The image is out of focus. The focal range
was perhaps not set for current setting and
the observation of the environment. Use the
Remote Focus slide knob on your control
panel to get your system into focus.
::
The image appears slightly violet; the correct
image shooting under the influence of
daylight is not foreseen; the infra-red portion,
which is invisible to the human eye, is often
no longer filtered in endoscopic cameras for
reasons of light sensitivity, since an IR filter
is already integrated in the cold light sources.
This is no cause for worry.
2.1.2 General tips
In the following, we have collected a few general
tips, which can help you to economically and fast
achieve good inspection results. The points do not
concern your work safety,but exclusively serve
the purpose of communicating general technical
knowledge.
Before introducing the probe into a cavity or a
pipeline, it must always be ensured:
::
That the application is free of acids, alkali,
oils and solvents. All non ph-neutral liquid
media may destroy different parts of the probe.
::
That the application is not impurified with
liquids, the viscosity of which lies below that
of water (e.g. glysantine). In such case, a
suitable special camera head with sealed fix
focus optic is needed.
::
That no elements in the application can be
activated, e.g. remote control valves, turbine
rotors, agitators etc.
::
For achieving meaningful inspection results,
the application ought to be cleaned in
advance, as long as depositions need not be
documented. In case of unclean plants, the
optic or the light out of the camera is dirtied
fast.
::
The farther you insert a probe, the greater is
the danger that it might get stuck. In
principle, an endoscopic probe can be more
easily inserted than extracted, as far as
straight, narrow and steeples pipelines are
not being inspected. In perimeters (e.g.
heating pipes at apparatus and reactors) this
can lead to self-obstruction – similar to a
lasso. Do not lose your nerves in such a
case- there are often different methods of
disengaging the probe without opening the
plant or destroying the probe. The risk of
getting stuck on steps is increased with the
employment of centring tools. In principle,
never use force while releasing! The
manufacturer offers a foreign parts retrieving
service. In order to limit the long-time action
of unknown substances, the probe ought to
be cleaned after use.
::
Mount your equipment basically in such a
manner, that it stands absolutely securely.
Fundamentally, the probe does not possess
the constructive characteristics of stopping a
free fall of the control device without
breaking. Through an insecure mounting,
you are principally seriously endangering
persons, perhaps working on levels beneath
you. At the same time, strong jolts are
resented by a rotating arc lamp, besides
shortening its lifetime, possibly accompanied
by total failure.
