1 Function description

1.1 Usage

The correlator SeCorr 08 permits to detect leakage points an
directly buried pressure line systems according to the correla­tion principle. Sensitive microphones are used to record leakage

noise on accessible installations and ttings. These recordings

are wireless transmitted to the correlator.

SeCorr 08 calculates then the exact leakage position using the

Fast Fourier Transformation (FFT = mathematic algorithm).

Supplementary functions are available to improve e.g., the indi­cation of leaks, to enter several pipe sections or to measure the
sound velocity.

The RT 06 radio transmitter can be used to measure fully auto-
matically the input level of the microphone and to set the level

control of the amplier to the optimum value. Characteristics and
parameters – such as the used microphone type, the charge state
of batteries and the amplier setting – are wireless transmitted to

the correlator for further evaluation.

1 Function description

Note:

These operating instructions are based on soft­ware release 4.X, with „X“ standing for any number.
The currently installed software version of your

SeCorr 08 is displayed after switching on the device.
Future releases are subject to change!

2.1 First use

CAUTION!

Before placing SeCorr 08 and RT 06 for the rst
time into service, make sure that all used batteries
are completely charged. If the batteries are only
partially charged, the capacity of the batteries may
be reduced thus leading to shorter operation.

2.2 Switching ON/OFF

1

Position both piezo micro- z
phones at accessible fitting
parts. If the circular magnet
is screwed on the piezo mi­crophone, it may be required

to remove the circular, rmly

adhering protective disk from
the magnet.

Plug both microphone con- z
nectors into the sockets of the

radio transmitter RT 06. If you
want to use only one RT 06, it

is required to connect a micro-

phone directly to input 2 of the
SeCorr 08.

On the RT 06, LED 1 must
be lit.

Connect the headphones to z

socket 3 of the SeCorr 08.

Switch on the SeCorr 08 by z

pressing the ON/OFF key for
a couple of seconds.

(blue radio trans­mitter in use)

The initial screen is briefly

displayed, containing informa­tion on the release number of
the software and the battery
capacity.

Then the central screen ap­pears (see back of cover
page). From this screen, you

ca n acc ess the individual

menus (menu key) or start the

desired functions.

Keep the z ON/OFF key pressed
until the device switches off.

Note:

The SeCorr 08 version with two transmitters permits
to connect a microphone directly two the SeCorr 08,

e.g., if a radio transmitter is defective (see also sec­tion 7.8.3).

CAUTION!

Connect always rst the sensor to the measurement
location (by coupling the microphone to the slide
valve, hydrant, etc.). Then, switch on the RT 06 by
plugging the sensor into socket 2.

This sequence of steps ensures that the automatic
amplication in the RT 06 is quickly and properly

set.

2 Use

The radio transmitter RT 06
can be operated with different

5

2

sensors, EM30 microphones
and the HA hydrophone.

It is recommended to use the

active lter ZF01, if interfering
noise is to ltered out or if only
a specic acoustic frequency

range is to be transmitted to
the correlator SeCorr 08.

The RT 06 is enabled when the sensor is plugged into socket 2.

Press the lter key 4 generally if plastic pipes are used. The right
LED 5 is lit to indicate the changeover. If this setting is selected,

only the low-pass frequencies are transmitted to the correlator.

This may help to increase the quality of the correlation mea­surement. If the RT 06 is switched on, all frequencies are always
transmitted; the left LED 6 is lit.

The transport handle on top of the antenna can be used for car-

rying the device.

LED 1 shows the state of the RT 06:
Operation: green
Undervoltage: ashed red
Charging: 1 x ashing green
Buffering: 2 x ashing green
No charging: red (because temperature below 0 °C)

3.1 ON/OFF key

Press this key to switch the de­vice on or off. Hold it pressed un­til the SeCorr 08 is activated.

If the key is pressed only shortly,
the currently running function is

stopped (e.g., a correlation in
progress). If you have opened

the menu, you can use the ON/
OFF key to return to the next
higher menu level. Press the key
only shortly.

If a correlation is stopped, the

diagram (correlation function)

can be zoomed in. If any key is
pressed, the display returns to
normal representation.

3.2 Rotary regulator

Turn the Rotary regulator to

move the selection or the cursor
to the left/right or up/down.

You can use the Rotary regulator
to change values in numerical

entry elds (e.g., pipe length).

Press the Rotary regulator once
to change the direction of move­ment from up/down to left/right or
vice versa.Pressing the Rotary
regulator has the same effect as
pressing the Enter key.
