1 Preface 7
1 Preface
Dear customer,
in the first instance we want to thank you that you made your decision on a product of OKM
Ortungstechnik GmbH.
With our team of specialists we guarantee that our products are under recurrent control. Our
specialists try to implement new developments in terms of further quality improvements for you.
Of course by selling our products we cannot guarantee that you really make a find during
your research. The recognition of hidden objects and structures depends on a hugh number of
factors - like you know. Determining factors are the dielectricity constant of the ground, the
grade of mineralisation and the dimensions of an object relating to its depth. Specially in very
wet soil, clay and sand with high conductivity of the ground, recording of the measured results
can be falsified strongly.
With this product you purchased a device which stood the tests in regular operation like all
other products of us. If you are interested in where our devices have gone into action please
visit our homepage.
For our company it is necessary that we protect our developments within the framework of
existing legislation to a patent or trademark registration. Therewith we offer you a higher
warranty while using our products.
Please take your time consecutively, read this user‘s manual and familiarize yourself with the
utilisation and operation of this FS-Reflexion.

Figure 2: Reflexion with control unit, transmitter and vibration transducer
Figure 2shows a general overview about the most important components of the FS-Reflexion.
The transmitter generate vibrations, which will be conducted or damped depending on the local soil
conditions. Via the seismic vibration transducer the control unit will receive measurement values, which
are used to draw conclusions to underground structures. The analysis take place immediately
on the monitor of the control unit or inside the software on a computer.

instrument make sure that the delivered external power supply is connected and powered on.
The button start is necessary to start a measurement in the Scan Mode.
The operating lamp indicates the state of readiness of the control unit and shines red, as soon as it
will be powered on.
The bluetooth lamp shines green, as soon as the bluetooth connection is established between the
control unit and the transmitter.
By using the keys (Previous operating mode) and (Next operating mode) you can select every
single operating mode of the main menu. To confirm your selection please press the button
(Activate operating mode). Within each operating mode the keys will have a different configuration,
which will be explained at the moment in time in this user manual.

The Power on and off button is used to power on (“|”) or off (“”) the Transmitter. After switching-on
the device the green Operating lamp is shining. After switching-off the device the lamp will go
out. The Operating lamp indicates also the charge condition of the internal batteries. During the
operation the color will change according to the charge condition from green (full charged) to
yellow, orange or red (low batteries). When the lamp is shining red it is necessary to recharge
the Transmitter.
Into the Socket for charging the delivered charger has to be connected to recharge the internal
batteries of the Transmitter. The charging procedure takes about 10 hours if the batteries are
completely empty.
The safety fuse protects the Transmitter against high charging or discharging current. During the
usage of the delivered charger there is no danger.
Attention: Use only the 16 A-safety fuse of same construction type if needed! Other safety
fuses or jumpers can cause fire or explosion.

5 Mode of operation 17
5 Mode of operation
In this section the physical principle of detecting subterranean voids with FS-Reflexion will be
described. The best measurement results you will receive, if you know how the measured values
are recorded and how they has to be analysed.
Figure 7: Schematic representation of the mode of operation
In Figure 7you can see the schematic representation of the mode of operation. The transmitter
generates vibrations in different frequencies, which will be transfused into the ground. During
this process each frequency will be generated only for a certain period of time until the next
frequency will be generated. While using the operating mode Fast Scan Mode the unit will not
pass through all available frequencies.
Depending on the condition of the subsoil, the different seismic waves will be transmitted
more or less into the ground. Especially applicable are dry and compact soils. Loosy or wet
soil types, like e.g. swampland or sand are less suitable. In case of a serious change inside
the ground, like e.g. caves, inclusions or fillings, the vibrations will be well transmitted or
absorbed. In case of an existing void, it will start to resonate in its own frequency. As a result
an heterodyne vibrancy will be delivered to its environment. This vibrancy can be measured
by the vibration transducer as soon as it reaches the surface of the ground. This amplification of
the origin vibration will be represented in the frequency-energy-graph of the control unit as a high
amplitude.
How deep the seismic vibrations can be transmitted into the ground, does strongly depend
on the condition of the soil (resistance, humidity). The more compact the soil is, the deeper

cavities can be located.
As shown in figure 7the transmitter can influence the vibration transducer if both are placed next
to each other in a too small distance. In this case the vibration transducer will only record the
vibrations emitted by the transmitter. This is the reason why the transmitter should be placed at
least 3 meters far away from the measured area and the seismic vibration transducer.

6 Operating modes 19
6 Operating modes
The device offers different operating modes which you can select in the main menu. In figure 8
the main menu with its functions is represented.
Figure 8: Representation of operating modes in the main menu
By using the buttons and you can switch between the operating modes. As soon as you
press the button the selected operating mode will start.
In the bottom right corner of the main menu the serial number of your device will be indicated.
In figure 8you can see the number RFX-AA-091007-1 which is our example.
The proper functions of the main menu will be explained in the following section in detail.
6.1 Fast Scan Mode / Deep Scan Mode
With the operating modes Fast Scan Mode and Deep Scan Mode you are able to do seismic
measurements. Here are the main differences of these two operating modes:
•In operating mode Fast Scan Mode you have the possibility to do a fast scanning. The de-
vice will not pass through all available frequencies. The frequency range of the transmitter
will not be traversed completely, which means that some frequencies will be skipped. It is
a raw measurement which is less accurate than a measurement in Deep Scan Mode. One
measurement procedure takes about 10 seconds.
•In operating mode Deep Scan Mode a complete seismic measurement takes place where the
transmitter pass through the complete range of frequencies. This measurement method is
much more accurate than a measurement in Fast Scan Mode. One measurement procedure
takes about 80 seconds.

User’s manual: FS-Reflexion 20
The recorded measurement values will be indicated in real time on the monitor of the control unit
and can be analysed immediately. In figure 9the graphical display is represented, to explain
the proper elements.

graph
Statistics
Progress indicator Keyboard configuration
Figure 9: Graphical display in the monitor of the control unit
The signal display shows the raw measurement values of the seismic vibration transducer. The mea-
surement results are shown in real time during the measurement. The measurement values in
the frequency-energy-graph will be calculated and represented only after finishing the measurement
procedure. Only these values are relevant for analysing the measurement. In section 9on page
44 you can find detailed information about the correct analysis of measurements.
The statistics represents at first the minimum and maximum of the raw data of the signal display
and after that the minimum and maximum incl. the appropriate frequency indication of the
frequency-energy-graph.
The keyboard configuration explains which buttons are configurated with which function. During
proceeding a measurement it can happen that some buttons are configurated with different
functions. Due to this indication the button configuration is easy visible.
The progress indicator consists of two parts, the progress bar on the left side and the information
on the right side next to it. The progress indicator is represented in figure 10 in large size.
