1 Technical description
Sebalog N-3 is a system for acoustically monitoring pipe systems. It has Log N-3 noise
level loggers and the Commander-3 as its basis. The Commander is used for
programming the loggers as well as reading out and analysing the recorded
measurements.
To monitor a zone, you can attach as many noise level loggers along the pipe as you
wish. They then perform regular noise measurements within a certain time window. The
user can set the exact measurement time window and other parameters before
measuring begins. The level and frequency of the individual measurements are saved in
the logger. Even the quietest noise is saved as an audio recording.
After measuring, you can collect the loggers, call up the readings and check for leak
noises, and then put them back in a new zone, for example. This allows all the zones in
a pipe system to be checked in succession for leaks.
However, the loggers can also be left in the same zone to monitor it permanently. The
measurements from the individual loggers are then read out on site. Just approaching
the installed loggers with the Commander or another reader will suffice. Wireless data
transfer takes place automatically. Ideally, all you have to do is drive by where the
loggers are being used.
The Sebalog N-3 system has the following features:
• Loggers can be used temporarily, permanently or in the network
• Wireless communication between all components
• Audio data recorded directly in the logger
• “Commander-3” with colour display, USB port, large memory capacity, and
much more.
• Complete group/logger management without a PC
• History function
• Extended wireless range using repeater
• Logger available as TNC version with external antenna

Important and common terms

2 Important and common terms
The Commander-3 can be operated in two different user modes (see page 23):
• Easy mode
• Professional mode
You can switch between these modes in system settings menu (see page 25).
These two values are identified each time a noise logger performs a measurement:
• “Level”
… is the noise level (volume) of a measurement
• “Frequency”
… is the frequency in the measurement’s frequency spectrum with
the greatest deflection
ESA stands for “Extended Spectral Analysis” and means that noise level and frequency
are combined in one reading using a mathematical formula. This results in an extended
view of the measured data, which makes the leak probability and position visible in
relation to other loggers. The dimensionless ESA value can be between 0 and 100. The
higher the ESA value, the higher the leak probability and the shorter the distance from
the logger to the leak.
In order to analyse the recorded measurements, the noise loggers must be read after
measuring, i.e. the data in the loggers is accessed wirelessly with a reading device
(Commander/Reader/PC). It is possible to do this in the following ways:
Group mode
“Lift&Shift” “Patrol” “Network”
The loggers are collected;
data is read out wirelessly
in the office
The loggers remain at
the place of use;
data is read out
wirelessly while
“driving by”
All the installed loggers
are networked with each
other and connected to
a GSM box;
data is read out via
mobile radio from the
office
The method must be chosen for reading out the measured data before the measuring
work is performed. Before measuring, the mode decided on is permanently assigned to
the loggers or logger groups. After that, only loggers that have been configured for
reading using “Patrol” can be read with “Patrol”, for example, and not with “Lift&Shift” or
“Network”. The same applies to the other group modes.
User mode
Level and frequency
ESA value
Group mode
Important and common terms
14
The Commander can only ever interact with a single registered logger group. This group
is called the “workgroup”. It is not possible to program or read loggers from another
group.
The “measuring window” is the time during which a logger is programmed to carry out
measurements, e.g. from 2 a.m. until 4 a.m. in the morning.
A measuring window could also be referred to as a “measuring day”.
A measuring period refers to the time span that passes between programming and
reading a logger. A measuring period can therefore last 1 to 100 measuring days.
There is a certain basic noise level in each pipe system. This basic noise level is
referred to as the “leak threshold”. This level may be known or estimated based on
experience. If the lowest measured noise level in a section of pipe is above the leak
threshold, there is presumed to be a leak.
If the level of the quietest noise in a measuring window is above the previously found
leak threshold (see above), the logger goes into “leak status”. This means, for example,
that when this logger is read, a warning appears on the reader indicating that there is an
increased probability of a leak close to the logger.
The term “leak value” combines the three measurement results – level, frequency and
ESA value – determined for the quietest noise in a measuring period.
If a noise logger has been switched off (i.e. it has stood “on its head” for at least
3 minutes), it is in “configuration mode” after it is switched back on. This means:
• The previous programming has been deleted. The logger is now unprogrammed.
• Switching off has not deleted the previously saved measurement results. They are
still in the logger’s memory and can be accessed by a reading device, but only by
single interrogation (see page 54).
• The logger is ready for wireless operation and waiting to be contacted by the
Commander or PC.
The logger remains in configuration mode until it is reprogrammed.
Each device in the Sebalog N-3 series has a unique serial number (SN). You will find it
on the type plate of the device.
All loggers, repeaters and GSM boxes also have an identification number (ID) which can
be used by the Commander or the SebaDataView software to manage them. You will
also find the ID on the type plate, or on a separate plate on the device. The identification
number is identical to the last six digits of the serial number.
When inputting an ID, the preceding zero digits can be omitted.
Thus, if the ID is “000815”, you need only enter “815”.

3 The loggers
3.1 Function
The noise loggers are installed along a section of pipe directly on the pipe, or directly on
fittings on the pipe.
Within the configured measuring window, they perform regular noise measurements,
each 3 seconds in length. The volume level and frequency of each measurement are
saved in the logger. W hile the noise level alone only records the general existence of a
leak, together with the frequency it also provides information on the approximate
distance in relation to other loggers.
The measurement results gathered by the logger can be queried later using a reading
device (Commander/Reader/PC).
The quietest noise of the last measuring window is saved as an audio file. After reading
out the data, you can actually listen to the assumed leak noise and immediately decide if
it is a leak noise or background noise.
The “Real time measurement” function can be used to observe a logger “live” as it
measures (see page 58).
With the “Direct recording” function can be used to listen to a noise in a pipe (see page
63).
Communication with the loggers is performed with short range radio only.
The loggers
16
3.2 Design
All noise loggers have a highly sensitive microphone with a large dynamic range, a data
memory and a lithium battery inside. The standard loggers also have an internal radio
antenna.
The loggers have the following external characteristics:
Element Description
Hole (M5 thread)
For fitting the supplied ring, which can be used for carrying the logger and
pulling it out of the shaft.
Label with identification number (ID)
Each logger has its own six-digit identification number.
Type plate
The last six digits of the serial number (SN) on the type plate of the device
are identical to the ID.
Marking
Must always face upwards when the logger is fitted horizontally.
Magnetic foot
Can be unscrewed and replaced by an adapter, or similar, from the
assembly accessories.
The special TNC version of loggers have no internal antenna. Instead of the hole for the
assembly ring they have an antenna socket for connecting an external antenna.
Introduction
Standard version
TNC version
“Head” of the logger
“Foot” of the logger
The loggers
17
3.3 Switching on and off
The noise loggers have an internal tilt switch and are switched on and off simply by
turning them over.
Loggers standing on their foot are
switched on.
Loggers standing on their head for longer
than 3 minutes are switched off.
Each time a logger is switched on, its configuration data is reset to the default
values. The time internally is also lost. Therefore, whenever the logger is
switched back on, it must be reprogrammed (see page 50).
3.4 Memory
A logger’s internal memory allows a maximum of 100 pairs of values (the level and
frequency of a measurement) to be recorded.
Furthermore, the quietest recording of the last measuring window is saved as an audio
file (3 seconds in length).
Circular buffering is used, with the oldest stored measuring window being deleted after
100 measurements.
3.5 Power supply
Each logger has an internal lithium battery.
The actual battery lifetime depends on the intensity of use.
If a logger is always operated using the default configuration data, factory-set in the
Commander, a battery lifetime of up to 5 years is possible.
Longer measuring periods and increased wireless activity/availability shorten the life of
the logger battery. Severe fluctuations in climatic conditions also have a negative
impact.
Flat batteries cannot be recharged. They must be replaced.
SebaKMT or an authorised service partner must change the batteries.
Otherwise, water- and dirt-resistance of the logger cannot be guaranteed.
The Commander
18
4 The Commander
4.1 Function
The Sebalog Commander 3 is the mobile programming and reading device for noise
loggers in the Sebalog N-3 series. The Commander is used to program the noise
loggers before measuring. After measuring, the recorded data in the loggers can be
queried with the Commander. Both current and older data can be displayed on the
device’s screen and analysed in greater detail. Furthermore, a real time measurement
can be performed (see page 58).
After connecting the supplied headphones, you can play back audio files of leak noises.
It is also possible to listen to the current noise in a pipe (see page 63).

4.4 Basics of operation
The Commander is very simple to operate and intuitive in principle. Navigation within the
menus is done exclusively with the aid of the selector knob as follows:
Turning = select
Pressing =
open/confirm
(ENTER function)
The selected element appears on a black background:
In Easy Mode, use the ESC button to exit each menu. This immediately returns you
to the start screen. Any functions started are cancelled.
In Professional Mode, you can use the symbol at any time to return to the previous
menu level. Pressing the ESC button once makes the hidden main menu bar
reappear. Pressing it a second time takes you back directly to the start screen.
With the aid of the selector knob, not only can individual menu items be accessed but
also settings can be changed and parameters adapted. Please proceed as follows:
select
