2 SeCorr system
2.1 General information about the system
The SeCorr system works using the correlation method, whereby
measurements are taken at two ttings (e.g. slide gate, hydrant)
at the same time. Highly sensitive microphones record the noises
at the ttings. The two microphones are each connected to a
radio transmitter. The radio transmitters transmit the signals to a
receiver – the correlator. The correlator determines the run time
difference between the signals, i.e. the time lag between the noises reaching the two measuring points. This is then used, together
with the pipe data, by the correlator to calculate the leak position.
The advantage of the correlation method is that the leak posi-
tion is determined independently of the hearing and experience
of the user.
The system features a function which can also locate leaks
acoustically if there is no suitable technology available specically for pinpointing or prelocation.
2.2 System components
2.2.1 Overview
SeCorr is a modular system. The main components of the sys-
tems are:
● C 200 receiver (correlator)
● 2 RT 200 transmitters (1 pair)
− Transmitter 1 with blue ag
− Transmitter 2 with orange ag
● 2 microphones, e.g.:
− UM 200 universal microphone
OR
− HY 200 hydrophone
One microphone is required for each
same type of microphone must always be used for the two
transmitters.
RT 200 transmitter. The

Page 14
● F8 wireless headphones (optional)
● AC 200 SK 4 case
The system can be transported and stored in the case. The L
AC/DC adapter can be used to recharge the batteries of the
C 200, RT 200 and F8 components simultaneously inside the
case.
Accessories can be added to the system at any time.
Note:
Information about the F8 wireless headphones can be found in
the relevant operating instructions.
2.2.2 C 200 receiver
The C 200 receiver receives data from the RT 200transmitter.
The receiver calculates the leak position from the run time difference between the signals of the two receivers.
The
C 200 receiver is also known as a correlator.
2.2.2.1 Setup
Overviews with the names of all the parts of the receiver can be
found inside the front cover (g. 1 and g. 2).
Its symmetrical housing means that it can be operated by both
right-handed and left-handed users with ease.
Touch screen
The receiver features a touch screen. Certain areas of the touch
screen are touch-sensitive. Actions are performed by touching
these areas (buttons).
All of the buttons have a thick, dark grey outline.
Only your nger or a touch pen should be used to operate the
touch screen.
●
Always touch the buttons briey without exerting too much
pressure.

NOTICE! Risk of damage
The surface of the touch screen is sensitive.
● Do not use any hard or sharp objects to tap the screen.
● Protect the touch screen against aggressive substances (e.g.
acidic or abrasive detergents).
A list of symbols that might appear on the touch screen can be
found in
section 6.2 on page 71.
Light sensor
The light sensor analyses the ambient lighting conditions.
If the automatic brightness setting is enabled, the light sensor
always adjusts the brightness of the touch screen to the ambient
lighting conditions.
Information about the automatic brightness setting can be found
in
section 4.4.1.4 on page 55.

3.5 Optimising the correlation result using lters
Note:
The SeCorr system has lter options for various purposes. An
overview of these can be found in
section 2.3 on page 20.
Filters can help optimise the correlation result and thus locate
leaks more reliably. Filters are set in the frequency graph.
A well-applied lter will have the following effect on the correlation curve:
●
Peaks will be displayed in higher quality, i.e. sharper, with
steeper sides, etc.
● The peak of a potential leak noise will be accentuated com-
pared to other noises (e.g. sound interference).
Aim of optimisation
The aim is to obtain the highest quality peak possible in the correlation curve.
3 System in use │ 31
Page 40
3.5.1 Filter menu (overview)
The Filter menu displays the frequencies, correlation curve and
the result of the measurement as a graph.

In the settings you can specify whether to display one or two
functions (Measurement menu > Filter basis).
If two functions are displayed:
● Areas in which the two functions overlap are shown in black.
● If the values of one function are lower than the values of the
other function across the whole frequency range, you will only
be able to see the function with the higher values and the
overlap.
One lter is always set in the frequency graph. This lter can be
changed.
● The lter currently applied will be shown on the Current lter
button.
●
The values of the lter limits will be specied on the Lower
lter limit and Upper lter limit buttons.
Dashes will be shown instead of digits if an automatic lter calculates the entire frequency range as the passband.

3.5.1.2 Correlation curve
The run time difference between the signals of the two transmitters is displayed in the correlation curve.
Fig. 22: Correlation curve with marker (red rectangle)
The area around the highest peak of the curve is marked with a
red rectangle. This marker indicates the calculated leak position.
If a correlation curve shows several signicant peaks, a plausibility check should be carried out (section 3.6).
3.5.1.3 Quality of peak
The sharper or clearer the peak, the better the quality. The quality
can be improved by setting lters.
The quality of a peak is rated by dots. The more black dots, the
higher the quality.
Fig. 23: Quality of peak

Page 46
3.6 Plausibility check (moving the marker)
The correlator cannot determine whether there is an actual leak
at a calculated position or whether the noise is interference (e.g.
open house connection).
This can pose a problem if the correlation curve shows more than
one signicant peak. In such cases, we recommend checking the
plausibility of the correlation result.
The Filter menu is open.
1. Move the marker in the correlation curve to another peak.
− To do this, tap the relevant position in the curve.
2. Read off the recalculated leak position.
3. Check the conditions on the ground.
− Is there another noise source at the calculated position?
3.7 Listening to noises
Note:
F8 wireless headphones are required for listening to noises.
3.7.1 Information about the radio connection during listening
The
C 200 receiver and F8 wireless headphones communicate
by bidirectional SDR (SDR: Sewerin Digital Radio).
SDR transmits uncompressed signals in real time. Radio interference can, therefore, cause a short clicking noise in the headphones.
SDR uses the same frequency ranges as, for example, WLAN
or Bluetooth. In rare cases, SDR can, therefore, be affected by
other radio connections.
These effects can be minimised by the following measures:
● Avoid drops in the SDR radio connection caused by obstruc-
tions, e.g. your own body. Carry the receiver in such a way
that the transmission path to the headphones is not obscured.
38 │ 3 System in use

If you are carrying electronic devices that use WLAN and Bluetooth directly on your body: Disable the WLAN and Bluetooth
function if necessary.
3.7.2 Transmitter menu (overview)

● F8 wireless headphones (NiMH rechargeable battery)
The typical charging time is less than 7.5 hours. The batteries
are protected against overcharging. The components can, there
fore, remain connected to the power supply after they are fully
charged.
Always observe the permitted temperature range during charg-
ing. If the temperature falls below or exceeds the limit values,
charging stops until the temperature returns to within the permitted range.
There are two ways of charging the components:
● All components at the same time in the AC 200 SK 4 case
● Each component individually using the AC/DC adapter or ve-
hicle cable
-
5.1.1 Charging the batteries in the case
The batteries of the components can all be charged simultaneously in the
power supply using AC/DC adapter L or vehicle cable L.
The AC/DC adapter and vehicle cable are available to buy as
accessories.

5.2 Handling faulty lithium-ion rechargeable batteries
Lithium-ion rechargeable batteries are always considered dangerous goods for transportation.
The transportation of faulty lithium-ion batteries is only permitted under certain conditions (e.g. must not be transported as air
freight). Where transportation is permitted (e.g. by road or rail),
it is subject to strict regulations. Faulty lithium-ion batteries must,
therefore, always be removed from components before shipping.
Transportation by road or rail must occur in compliance with the
current applicable version of the ADR1 regulations.
NOTICE!
Risk of damage when removing lithium-ion batteries
There are parts in the battery compartments of the components
which can get damaged when removing the batteries.
● Lithium-ion batteries must only be removed if there is reason-
able suspicion that they might be faulty.
● Only SEWERIN Service personnel or an authorised specialist
may replace rechargeable batteries.
5.2.1 Identifying faulty batteries
A lithium-ion battery is considered to be faulty if one of the following criteria applies
2
:
● Housing damaged or severely deformed
● Fluid leaking out
● Smell of gas
● Measurable increase in temperature when switched off (more
than warm to touch)
● Plastic parts melted or deformed
● Connection leads melted
