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.
