Introduction 1
SpotChecker Issue 02, 03/2009 7
Safety information1.1
The SpotChecker has been designed and tested ac-
cording to DIN EN 61 010 Part 1, Safety requirements
for electrical measuring, control and lab equipment,
and was technically in perfectly safe and faultless con-
dition when leaving the manufacturing works.
In order to maintain this condition and to ensure a
safe operation, you should urgently read the following
safety information before putting the instrument into
operation. When connecting other equipment to the
SpotChecker, such as the power supply unit, follow
particularly all safety instructions that apply to these
devices.
A Attention:
The SpotChecker is an instrument for materials
testing. Any use for medical applications or other
purposes is not allowed!
The SpotChecker may only be used in industrial
environments!
Power supply
The power supply for the SpotChecker is carried out
via one or two batteries or via a connected power sup-
ply unit. The power supply unit may only be used in-
side buildings and may not be exposed to moisture or
liquids. Follow all safety instructions that are applica-
ble for the power supply unit used.
A Attention:
Never open the housing of the power supply unit. The
power supply unit does not contain any user-service-
able parts.
Software
According to the current state of the art, software is
never completely free from errors. Before using any
software-controlled test equipment, please make sure
that the required functions operate perfectly in the in-
tended combination.
Introduction Safety information

Further information
A Attention:
Observe the documentation for the other equipment
connected to the SpotChecker, such as computer or
power supply unit. The documentation contains impor-
tant safety instructions and information about permit-
ted uses.
The SpotChecker software provides extensive online
help which is always available to you when working
with the system. In this operating manual you will find
any additional information that you might require.
If you have any questions about the use of your test
equipment, please contact your nearest representative
of GE Sensing & Inspection Technologies.
If you install additional software on the computer, GE
Sensing & Inspection Technologies will not bear any
responsibility regarding the influence this may have on
SpotChecker operation. The existing software drivers
may be overwritten in such a case.
Defects/errors and exceptional stresses
If you have reason to believe that a safe operation of
your SpotChecker is no longer possible, you have to
disconnect the instrument and secure it against unin-
tentional reconnection.
A safe operation is e.g. no longer possible
❚ if the instrument shows visible damages,
❚ if the instrument no longer operates perfectly,
❚ after prolonged storage under adverse conditions
(e.g. exceptional temperatures and/or especially
high air humidity, or corrosive environmental condi-
tions),
❚ after being subjected to heavy stresses during
transportation.

Important information on ultra-1.2
sonic testing
Please read the following information before using
your SpotChecker. It is important that you understand
and observe this information to avoid any operator er-
rors that might lead to false test results. This could re-
sult in personal injuries or damages to property.
Preconditions for testing with ultrasonic test
equipment
In this operating manual you will find essential infor-
mation on how to operate your test equipment. In ad-
dition, there are a number of factors that affect the
test results. A description of these factors would go
beyond the scope of an operating manual. Let us
therefore only mention the three most important re-
quirements for a safe ultrasonic inspection in this con-
nection:
❚ the operator training,
❚ the knowledge of special technical test require-
ments and limits,
❚ the choice of appropriate test equipment.
Operator training
The operation of an ultrasonic test device requires a
proper training in ultrasonic test methods.
A proper training comprises for example adequate
knowledge of:
❚ the theory of sound propagation,
❚ the effects of sound velocity in the test material,
❚ what happens to the sound wave at the interface
between two different materials,
❚ the propagation of the sound beam,
❚ the influence of sound attenuation in the test ob-
ject, and the influence of surface quality of the test
object.
Lack of such knowledge could lead to false test results
with unforeseeable consequences. You can contact
for example NDT societies or organizations in your
country (DGZfP in Germany; ASNT in the USA), or
GE Sensing & Inspection Technologies, for informa-
tion concerning existing possibilities for the training of
ultrasonic inspectors as well as on the qualifications
and certificates that can finally be obtained.
