1 Notes about this document
1.1 General
These operating instructions describe the parabolic sensor DBS30 as an accessory for the
ultrasonic measuring device SONOCHEK. These operating instructions contain important
information regarding safe operation as well as all information for proper and efficient use. They
must therefore be read prior to startup and all other steps.
Separate operating instructions exist for the light spot target device (Toppoint VI).
Read the operating manuals prior to startup and all other steps.
The parabolic sensor DBS30 must only be used by users who have read
and understood all the safety instructions in these operating instructions
and the operating instructions for SONOCHEK.
This document was created with due diligence. PRUFTECHNIK does not guarantee the
completeness, correctness and currency of the data presented here and is not liable for errors
or omissions.
1.2 Symbols Used
References to hazards or special information are indicated as follows:
Warns of immediate dangers, which if ignored may result in permanent
health damage and/or severe property damage.
Warns of dangers, which if ignored may lead to injuries and/or property
damage, including financial losses from operational impairments.
Warns of dangers, which if ignored may lead to property damage,
including financial losses from operational impairments.

2 Description of the parabolic sensor DBS30
2.1 Applications and intended use
The parabolic sensor is used for precise detection of ultrasonic waves across distances of up to
25 m. The following test steps can be carried out in conjunction with SONOCHEK:
Detection of leaks on compressed air, gas and vacuum systems,
Detection of electrical partial discharges and insulation damage,
Detection of leaks at windows, doors, cabins, vehicles or containers
(in combination with an ultrasonic transmitter DBT10).
2.2 Functional principle
The parabolic mirror reflects ultrasonic waves and focuses them on the ultrasonic microphone.
The ultrasonic microphone in the sensor converts sound pressure fluctuations in the air into
an electrical signal over a broad frequency range. This electrical signal is already amplified and
digitized in the sensor. Further data processing and output is carried out in the measuring
device SONOCHEK.
The target laser and the light spot target device assist in precise localization of damaged
points. If the sensor points towards the damaged point during the search, this point can be
detected by using acoustic signals by pivoting the sensor and searching for a local sound level
maximum. The damaged point can be marked with a target laser. The damaged point that is
marked can be targeted with the light spot target device.

3 Operation of the parabolic sensor DBS30
Eye injuries possible!
The target laser (laser class 2) cancause serious eye damage. Never look into
the laser beam.Never point the laser at other people or vehicles. Note that
reflected laser light can also cause eye injuries upon extended exposure.
In the very rare event that the parabolic mirror breaks, sharp edges may
arise that can cause cuts. When using the sensor, ensure that the parabolic
mirror does not get damaged.
Note!
The material of the parabolic mirror can be damaged by scratches. These
can affect the functionality of the sensor. Careful handling of the sensor
can prevent scratches.
3.1 Installation and removal of the parabolic mirror
Danger of the parabolic mirror being broken
Protect the parabolic mirror from pressure loads.
To install the parabolic mirror:
Hold the sensor handle with one hand and the parabolic mirror on the parabolic mirror holder
with the other so that the mirror points in the test direction of the sensor.
Guide the parabolic mirror holder into the plug-in position on the sensor from above and
fasten it by turning the set screw.
To remove the parabolic mirror:
Hold the sensor handle with one hand and loosen the set screw on the parabolic mirror
holder with the other.
Grip the parabolic mirror holder from above and carefully pull it out of the plug-in position on the
sensor.

3.2 Connecting the sensor to SONOCHEK
Damage to the plug-in connectors possible!
Note the mark with the red dot, which specifies the plug-in position on the
bushing and plug.
Connect any end of the sensor cable according to the red markings on the sensor
The sensor is powered via the cable and the measurement data is automatically transferred
to SONOCHEK.
The sensor is ready for operation once the LED of the operating display illuminates green.
Note!
The light spot targeting device is powered by a separate battery.
3.3 Starting and stopping measurements
Measurements can be started or stopped either via the red function key on the sensor or via
one of the measuring applications in SONOCHEK (see SONOCHEK operating manual).
3.4 Lightspot target device
3.4.1 Switching on and off
The light spot targeting device is powered by a separate battery.
Make sure that the light spot targeting device is off when the parabolic sensor is not in use.
Turn the brightness control to position R or G.
3.4.2 Changing the brightness
The brightness of the light spot can be adjusted on the control dial. This can be done in 5 steps
for red and green respectively.

3.4.3 Changing the battery
Open the battery compartment with a suitable screwdriver.
Exchange the battery. Observe the polarity as shown in the illustration.
Close the battery compartment.
3.5 Cleaning and maintenance
Incorrect cleaning and aggressive cleaning agents can damage the
parabolic mirror of the sensor. Do not use solvent-based cleaning agents
under any circumstances to clean the parabolic mirror.
The sensor and parabolic mirror are maintenance-free. They can be cleaned on a regular basis
from the outside with a damp cloth and a mild, non-abrasive cleaning agent.

Disposal Parabolic sensor DBS 30

SONOCHEK 09.2018
4 Disposal
Electrical and electronic equipment may pose health and environmental risks if disposed of
improperly. For this reason, it must not be disposed of as general household trash according to
the WEEE directive 2012/19/EU (Waste Electrical and Electronic Equipment Directive), but
rather must be handed over separately to designated collection points or sent back to the
manufacturer.
The following symbol on the device indicates the legal obligation to dispose of electronic
equipment at a separate disposal facility.
It be subjected to predefined recycling processes (e.g. with respect to the batteries or circuit
boards), which make safe, environmentally-friendly recycling or separate disposal of different
equipment components possible.
The return of old equipment is regulated differently by region. Check with the responsible public
body about the redemption conditions for commercially used electronic devices. The device and
the battery do not contain any substances that are hazardous to health and that must be labeled
separately with respect to disposal, such as mercury (Hg), cadmium (Cd), lead (Pb) or
hexavalent chromium (e.g. in galvanized parts or circuit boards).
