• For storing the device, use the transport case included in
the scope of delivery in order to protect the device from
external influences.
• the storage temperature complies with the values specified
in the Technical data
• Remove the batteries from the device.
Operation
Inserting the battery
Insert the supplied battery in the SL800R and the SL800T before
first use.
Note
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
sliding down the cover.
2. Use the battery clip to connect the 9V battery with correct
polarity.
3. Place the battery with the battery clip into the battery
compartment.
4. Slide the cover back onto the battery compartment until it
locks in place.
Inserting / exchanging the probe
The SL800R can be equipped with various probes.
The scope of delivery includes a structure-borne and an
airborne sound probe.
The structure-borne sound probe serves the purpose of
detecting material-borne ultrasonic frequencies via direct
contact of the object to be examined (e.g. a ball bearing).
The airborne sound probe serves the purpose of detecting
airborne ultrasonic frequencies even at a distance of up to
several metres.

Connecting the headphones
It is recommended to connect the supplied headphones to the
SL800R at all times. Human hearing already perceives very subtle
signal changes with regard to its volume and intensity, so in
addition to the LED indication 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 high-intensity
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.

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 devices' 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 devices have become adjusted to the
changed conditions before using the devices.
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 bar graph
might not indicate a change despite full intensity. If so,
use headphones to work with the acoustic component.

Using the SL800R with airborne sound probe
The airborne sound probe is suitable for the following fields of
application:
• Leak detection at exposed lines and pipes
• Proving the leakage-related loss at 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
üThe airborne sound probe is assembled.
üThe SL800R is switched on.
üThe volume control at 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 intensity via the thumbwheel(3)
until there is a deflection on the bar graph(2).
ðThe receiver is now set to high sensitivity!
4. Carefully increase the volume at the headphones(14) until
you can hear a sound.
5. Now move the airborne sound probe towards the
ultrasound source.
6. 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.
7. Whilst approaching the source, the sound grows louder
and the number of illuminated LEDs on the bar graph
increases.
8. If required, adjust the intensity via the thumbwheel(3).
Using the SL800R with structure-borne sound probe
The structure-borne sound probe utilizes structure-borne sound
as bearer of inner states and processes. Hence, the device
combination works like an electronic stethoscope.
The structure-borne sound probe is 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
üThe structure-borne sound probe is assembled.
üThe SL800R is switched on.

Using the SL800T with SL800R and airborne sound probe
Use the SL800T with the airborne sound probe for the following
fields of application:
• Tightness testing to determine the cause of energetic
defects, e.g. at doors or windows
• Checking containers, housings or climatic chambers for
tightness
• Subjecting tanks or containers to ultrasound so as to test
sealing components
Info
In case of larger rooms the SL800T should be
positioned near potential weak spots so as to make it
easier for them to be detected.
üThe airborne sound probe is mounted to the SL800R.
üThe volume control at the headphones is set to minimum.
1. Position the SL800T at the place to be inspected (e.g.

Errors and faults
The device has been checked for proper functioning several
times during production. If malfunctions occur nonetheless,
check the device according to the following list.
The device is not working:
• The battery might be empty. Replace it with a new one.
Signal from transmitter is not received:
• The battery might be empty. Replace it with a new one.
• Transmitter or receiver are not switched on or the distance
is too large. Reduce the distance from the transmitter that
is not received.
• The ultrasonic locating function of the SL800 strongly
