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.
EN Operating manual – ultrasonic detector SL3000 4
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 16 Hz and 20,000 Hz.
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.
5 Operating manual – ultrasonic detector SL3000 EN
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 -42 dB to 0 dB in increments of 2 dB. The default setting is -22 dB.
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.
50 cm from the airborne sound probe.
3. Carefully increase the volume at the headphones until 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.
EN Operating manual – ultrasonic detector SL3000 6
Using the attachments for the airborne sound probe
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.
19
2. If you no longer need the adapter, carefully pull it off the airborne sound probe.
17
18
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 headphones until 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.
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.
