1 Introduction

1 Introduction

The Stethophon 04 is an electroacoustic listening device used
to detect leaks.

The device's probe tip records the natural vibrations of the object
of examination. The Stethophon 04 displays a relative measure-
ment according to the internal amplication of the vibrations, and

emits the corresponding noise through the headphones.

Ranges of use:

z Leak detection in the water distribution network

z Inspecting house service connections

z Inspecting and pinpointing damage in compressed air sys-

tems

z Troubleshooting in heating and sanitation facilities in build-

ings

z Bearing inspection on machines

2.2 Intended use

The Stethophon 04 is a sensitive measuring device. It may only
be used for listening to sounds.

The device is suitable for both indoor and outdoor use. There are

special accessories available for both applications to optimise
the measurement results and prevent operating errors. Please
contact our sales department for advice.

The manufacturer accepts no responsibility for any damage

or harm caused to persons or property as a result of improper
use.

2.3 Safety information

Risk of personal injury (health risk)

z You could injure yourself or others with the tip of the device

probe. Handle the device carefully therefore when transporting
it and using it to measure.

z The device has an automatic hearing protection function. How-

ever, only set the volume as loud as is necessary to analyse
the noise. Excessive noise can cause permanent damage to
hearing!

Risks to the device

z Do not drop the device. This could damage the internal mi-

crophone.

z Never open the housing (except the battery compartment).

Failure to observe the above instructions will invalidate the
