Information about the device
Device description
The device SL3000 is used to locate faulty components in
various systems. It is based on ultrasonic signals generated e.g.
due to friction on faulty parts, inside electrical installations or
when gases escape under high pressure.
The ultrasonic signals are detected by the device, converted into
audible sound, and output with the corresponding intensity
through the headphones. At the same time, the ultrasound level
is indicated graphically on a display.

Operation
Inserting the batteries
Insert the supplied batteries into the device before first use.
Notice
Make sure that the surface of the device is dry and the
device is switched off.
1. Open the battery compartment at the rear of the device by
unscrewing the cover.
Inserting / exchanging the probe
The device can be equipped with various probes.
The scope of delivery includes an airborne sound probe.
The airborne sound probe serves the purpose of detecting
airborne ultrasonic frequencies even at a distance of up to
several metres.
In order to assemble or exchange a probe, please proceed as
follows:
1. Remove the probe, if any, by pressing the release button at
the probe and carefully pulling the probe out.
2. Insert the probe into the connector. The probe socket is
provided with a notch allowing for one plug position only.
The plug must noticeably click into place.
2. Insert the batteries with correct polarity.
3. Screw the cover back onto the battery compartment.

Operating manual – ultrasonic detector SL3000
Connecting the headphones
It is recommended to connect the supplied headphones to the
device at all times. Human hearing already perceives very subtle
signal changes with regard to its volume and intensity, so in
addition to the indicative scale on the display you are provided
with a valuable acoustic component for a yet more precise
detection of ultrasound sources.
Warning
Risk of hearing damage due to unknown, intense
ultrasound sources.
The sound spectrum perceptible by human ears lies in
the frequency range between 16Hz and 20,000Hz.
Hence, ultrasound is clearly outside of this range. As a
result potential, more or less intense ultrasound
sources in the immediate measuring environment go
unnoticed without technical aids. Nonetheless, they
can inadvertently lead to hearing damage if the
auditory system is suddenly faced with the highintensity ultrasound rendered audible by use of these
aids.
For that reason always set the volume control at the
headphones to minimum before starting a
measurement (narrow end of the wedge at the volume
control).
Increase the volume only slowly.
If necessary, reduce the volume when approaching a
potential ultrasound source.
Info
Regularly check the headphone cable for damages.
Avoid kinking, crushing or pulling.
ü The device is switched off.
1. Plug the jack plug of the headphone cable into the
headphones.
2. Plug the other jack plug into the device's headphone
connection.
General information regarding the work with the ultrasonic
detector
Info
Note that moving from a cold area to a warm area can
lead to condensation forming on the device's circuit
board. This physical and unavoidable effect can falsify
the detection result. In this case, the device emits
either no signals or they are incorrect. Wait for a few
minutes until the device has become adjusted to the
changed conditions before using the device.
Info
Please note that the measurement of an ultrasound
source always has to be carried out directly. There
must be no objects or persons located between the
airborne sound probe and the ultrasound source, for
this would hamper the detection process.
Info
In case of very weak ultrasound sources the scale
might not indicate a change. If so, use headphones to
work with the acoustic component.

Operating manual – ultrasonic detector SL3000
Switching the device on
ü A probe is assembled.
ü The headphones are possibly connected.
1. Press the power button(1).
ð The device is ready for operation.
ð The current sound level is shown on the display(11).
Adjusting the volume
The volume can be adjusted from -42dB to 0dB in increments
of 2dB. The default setting is -22dB.
1. Press the arrow buttons(3, 9) to increase or reduce the
volume.
ð The current volume will be indicated on the display.
Using the airborne sound probe
The airborne sound probe is suitable for the following fields of
application:
• Leak detection at exposed pressure lines and pipes
• Proving the leakage-related loss at exposed, gas-filled
supply networks also during operation
• Leak detection at high-pressure steam installations
• Localization of cracks, poor weld seams or worn flange
connections
• Leak detection at all accessible fittings and connecting
elements where processes take place in a vacuum or at
high pressure
• Detection of signs of wear at ball, roller or needle bearings
• Detection of cavitation e.g. in pumps or compressors
• Localization of electric arcs or corona discharge at
electrical components
ü The airborne sound probe is assembled.
ü The device is switched on.
ü The volume of the headphones is set to minimum.
1. Put on the headphones.
2. Test the volume by rubbing the fingertips of thumb and
index finger against one another at a distance of approx.
50cm from the airborne sound probe.
3. Carefully increase the volume at the headphonesuntil you
can hear a sound.
4. Now move the airborne sound probe towards the ultrasound
source.
5. Since the intensity of the ultrasound source to be detected
is initially unknown, down-regulate the volume at the
headphones as appropriate when approaching the source of
ultrasound.
6. Whilst approaching the source, the sound grows louder and
the scale indicates a higher sound level.

Using the attachments for the airborne sound probe
17
18
19
You can also use the probe included in the scope of delivery in
combination with the two attachments, which are also included
in the scope of delivery.
The attachments serve for an improved pinpoint location of the
ultrasonic signal:
• The acoustic horn(19) is suitable for detection even over
large distances of several metres.
• The shotgun(18) can be used for a more precise pinpoint
location over shorter distances.
The attached tip(17) can, for instance, be used for
checking weld seams or valve seals.
To use the attachments, please proceed as follows:
1. Carefully place the rubber grommet of the attachment onto
the airborne sound probe. Pay attention not to damage the
grid at the airborne sound probe.
Using structure-borne sound probes (optional)
A structure-borne sound probe utilizes structure-borne sound as
bearer of inner states and processes. The device combination
thus works like a stethoscope, but specifically for ultrasound.
Structure-borne sound probes are suitable for the following
fields of application:
• Early detection of wear at ball, roller or slide bearings
• Checking centrifugal pumps for cavitation
• Tightness tests of fittings
• Continuity testing or functional check of steam traps
ü The structure-borne sound probe is assembled.
ü The device is switched on.
ü The volume of the headphones is set to minimum.
1. Put on the headphones.
2. Hold the probe to the test object.
3. Carefully increase the volume at the headphonesuntil you
can hear a sound.
4. Move the probe towards the ultrasound source.
5. Down-regulate the volume at the headphones when
approaching the source of ultrasound.
6. Whilst approaching the source, the sound grows louder and
the scale indicates a higher sound level.
2. If you no longer need the adapter, carefully pull it off the
airborne sound probe.
Activating maximum value detection
1. Press the MAX button(5) to activate the function.
ð The maximum value of the current measuring cycle is
indicated in the bottom left corner of the display.
Switching on the display illumination
1. Press the light button(10) to switch the display illumination
on or off.
ð The illumination automatically switches off after approx.
20 s.
Adjusting the display contrast
The display contrast can be adjusted in order to adapt the
display to the individual ambient conditions.
The default setting is 50%.
1. Press the OK button(4) to open the contrast settings menu.
2. Press the arrow buttons(3, 9) to increase or reduce the
contrast.
3. Confirm the setting by pressing the OK button(4).
Switching the device off
1. Press the power button(1).
ð The display goes out.
ð The device is switched off.
