Function
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.
Features
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
User mode
Level and frequency
ESA value
Group mode
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”
• “Frequency”
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
… is the noise level (volume) of a measurement
… is the frequency in the measurement’s frequency spectrum with
the greatest deflection
“Lift&Shift” “Patrol” “Network”
The loggers are collected;
data is read out wirelessly
in 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.
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
13
Important and common terms
Workgroup
Measuring window
Measuring period
Leak threshold
Leak status
Leak value
Configuration mode
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.
Identification number
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”.
14
The loggers
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. While 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.
15
The loggers
3.2 Design
Introduction
Standard version
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:
“Head” of the logger
“Foot” of the logger
TNC version
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.
16
The loggers
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.
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
Loggers standing on their head for longer
than 3 minutes are switched off.
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.
17
The Commander
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
Navigation within the
menus
Exiting the menu
Adjustable parameters
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:
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:
Turning = select
Pressing =

The Commander
Virtual keyboard
Sorting loggers
To input comments or similar, a virtual keyboard appears on the screen, which is also
operated with the selector knob.
… deletes last character
… switches between upper- and lower-case
… inserts space
… confirms and completes input
Various menus list the individual loggers of a logger group. This appears in a table-like
form. You are able to re-sort these loggers by the criteria “Comment”, “Time of data
read-out” or “ESA value”. This can be useful for identifying certain loggers straightaway,
e.g. all loggers where a leak is suspected, etc.
To change the sort, apply the Sort button repeatedly. A small triangular symbol in the
header of a column indicates which criterion is selected and whether the loggers are
arranged in descending ▼ or ascending ▲ order.
Entering an
identification number
Examples of possible settings:
“ESA ▼” … sorting by ESA value (descending),
i.e. the loggers with a suspected leak are at the top of the list
“Date/time ▼” … sorting by time of the data read-out (descending),
i.e. the loggers most recently read are at the top of the list
“Date/time ▲” … sorting by time of the data read-out (ascending),
i.e. the loggers not yet read are at the top of the list
Various functions require the identification numbers (IDs) of loggers, repeaters or GSM
boxes to be given. When inputting an ID, all the preceding zero digits can be omitted.
Thus, if the ID is “000815”, you need only enter “815”.

The Commander
4.5 User mode
Introduction
How to identify
the user mode?
The Commander-3 can be operated in two different user modes.
Easy mode Professional mode
In Easy mode all the main functions of the
device are available. They can perform
most day-to-day work quickly and simply from programming a logger group to
analysing measured data on the
Commander. The individual applications
are structured very clearly; the user is
partly guided step-by-step from one action
to the next. Easy mode is therefore not just
suited to first-time users but also
experienced operators who prefer to use its
simpler menu structure.
If the Commander is in Easy mode, the following symbol is permanently displayed
above the infobar:
If the EasyGo symbol isn’t shown on the screen, the Commander is in Professional
mode.
In Professional mode all the functions of
the device are available to the user. This
allows the system to be better adapted to
the user’s requirements and conditions on
site. Difficult measurements can be
prepared more exactly and the results
evaluated and documented in more
different ways, etc. Some applications can
only be used in Professional mode, such
as using Repeaters or building a logger
network.
How to change the
user mode?
The user mode can be switched in the system settings (see page 26).

The Commander
4.6 Making a connection
4.6.1 Connection between the Commander and logger
Short range radio is used for communication between the Commander and loggers.
The Commander has an integrated radio module. After the antenna is connected
(standard or vehicle antenna), the device is ready for wireless operation.
The loggers must be switched on and wirelessly available (see page 52). The radio
range of a logger is affected by the conditions where it is used. To extend the range a
repeater can be used (see page 64).
4.6.2 Connection between the Commander and PC
Purpose
Making a connection
The connection between the Commander and a PC/laptop is made using the VK 77
connection cable supplied and is needed for the following tasks:
• Transferring measured data from the Commander to the PC.
• Transferring configuration data from the SebaDataView-3 software to the
Commander.
• Installing a firmware update on the Commander.
The Commander must be operated in Professional mode to connect it to the PC.
Proceed as follows:
Step Description
1
Select the button in the main menu bar.
2 In the next menu, select the Connect to PC button.
3
Use the USB socket on the Commander for connecting the cable to the PC.
Markings on the plug and socket ensure that the plug is lined up correctly. You
must feel the plug engage.
4 Select the Connect button on the Commander.
Result: The connection is made. The Commander is automatically detected by
the PC as a mass storage device. As soon as the Connected message on the
Commander’s screen appears, data can be transferred between the
Commander and PC.
If no connection is made, check the cable connection again. If necessary, disconnect
the Commander from the PC, restart it again, or perform a reset, and follow steps 1 to 4
once again.
Disconnection
To end the connection, select the Disconnect button on the Commander.
As soon as the Disconnected message on the Commander’s screen appears, the
connection cable can be removed.

4.7 Switching on the display lighting
The Commander’s screen has a backlight. It is activated by using the selector knob or
briefly pressing the I/O button . The lighting then remains on for a certain time period.
The length of this period (a maximum of 4 minutes) can be adjusted in the system
settings (see page 26).
4.8 System settings
You can use the System settings menu to customise various device settings to the
needs of the user.
Beginning at the start screen, follow the symbols.
The System settings menu opens:
When the Commander is in Professional mode, more settings can be changed

Select a period of time for the auto-off function.
If no entry is made for longer the specified time, the Commander
switches off automatically (never = automatic switch off
deactivated).
Activate/deactivate the key tone that sounds when the selector
knob is pressed.
Activate/deactivate the “History” function.
If the “History” function is activated, the measured data from
loggers remains stored in the Commander after they are read
out. They can then be called up at any time and displayed again.
If the function is deactivated, the previous data set is overwritten
when new data is read. Deactivating the function can be useful
because this saves memory space and the Commander can
work faster in certain situations.

The Commander
4.8.2 Extended settings in Professional mode
The following extended settings are only available in Professional mode:
Line Description
Logger list visibility
Logger found beep
Additional hints
Select table columns to be shown/hidden.
Various menu levels list the loggers of a group in a table on the
screen. The columns contain information about the loggers,
such as the logger ID and logger comment. To make the table
clearer, you can specify which columns are actually shown.
Switch the acoustic signal on/off that occurs when a logger is
found.
An acoustic signal sounds each time the Commander detects a
logger when reading out data. A corresponding message is
shown briefly on the screen.
When “patrolling”, this can happen several times in succession
because the loggers send data packets to the Commander at
regular intervals.
You can specify how often there is a signal or a message:
• always … acoustic signal each time the Commander
detects a logger
• only once if logger found … acoustic signal only when a
logger is detected the first time
• never … no acoustic signal
• beep and display only once … acoustic signal and
message on the screen only when a logger is detected the
first time
Decide if additional information shall be shown or not.
At various positions in the menu, special displays appear on the
screen, providing additional information about the current
functions. These displays can be deactivated.
Sorting order
Factory settings
Select the standard sorting order for loggers in tables.
Various menu levels list the loggers of a group in a table on the
screen. The criterion by which the loggers are sorted within the
table as standard can be specified..

4.9 Performing a hardware reset
If the Commander stops responding to inputs (from the selector knob or buttons), a
hardware reset can be performed.
Hold down the selector knob and the ESC button at the same time for about one
second. The Commander restarts automatically. This usually rectifies the malfunction.
If the malfunction persists after this normal reset, try the following: Hold down the
selector knob and the ESC button at the same time for about three seconds. The
Commander switches off. Wait about a minute before switching the Commander back
on with the I/O button . The device should now function correctly again.

4.10 Updating the firmware
Visit regularly the Downloads section at www.sebakmt.com for information about new
versions of firmware. You can install any updated versions of the firmware on the
Commander if they are available.
The current version of the Commander firmware installed can be found in the system
settings (see page 28).
To update the firmware, proceed as follows:
Step Description
1
First ensure that the Commander’s battery has sufficient power to update the
firmware (at least one bar on the battery symbol on the infobar (see page 20)).
If in doubt, recharge the battery first (see page 30).
2 Download the latest firmware archive from www.sebakmt.com and extract it to a
directory on your PC.
3
Connect the PC and Commander together via USB- (see page 24).
4
Copy the extracted files directly into the Commander’s main directory.
5
Disconnect the Commander from the PC (see page 24).
6
Switch the Commander off and then on again, or perform a reset (see above).
Result: The firmware update begins. A bar indicator shows the progress on the
screen.
During the update, no entries whatsoever must be made on the
Commander! This could cause the device irreparable damage.
CAUTION
After the procedure is complete, the device switches back on automatically.
Check the version number in the start screen to see if the Commander is
actually using the new firmware.
29
The Commander
4.11 Memory
The Commander has a 2 GB internal memory. This is sufficient to manage the data of
up to 1,000 logger groups, each with 1,000 loggers.
You can query the available memory space at any time in the system settings (see page
25).
4.12 Power supply
Internal supply
External supply
Automatic switch off
The Commander is fitted with an internal Li-ion rechargeable battery. This can power
the device for approximately 20 hours. The battery’s present charge level is shown
continuously by the battery symbol in the infobar on the screen.
If the battery is low, a warning on a coloured background appears on the screen:
• Yellow background … device can still operate for a few hours
• Red background + warning sound ... device will shortly switch off
The Commander can be operated using an external electricity source. Connect it to the
mains voltage or to your vehicle’s 12 volt socket. A guide on the round plug of the
charging cable and a groove on the charging socket of the Commander specify the
correct alignment of the plug.
As soon as the Commander is connected to the external power supply, its battery is
charged up automatically. This is shown by the red charging indicator light and by the
arrow in the battery symbol at the bottom right of the screen. Charging takes
approximately 12 hours. The battery is fully charged once four bars are shown in the
battery symbol. After the battery is fully charged, the Commander switches to trickle
charging.
During charging, the ambient temperature should be between
10°C and 40°C (50°F and 104°F). Otherwise the device could be damaged!
Only use the supplied charging cable to connect the Commander to

5.1.3 Defining a workgroup
More than one group of loggers can be registered in the Commander. However, the
Commander can only work with one of these groups at a time. This group is called the
“workgroup”.
Specify the workgroup for the impending measurement session. Please proceed as
follows:
Step Description
1
In the main menu, select the System settings button.
2 In the next menu, select the Change group button.
Result: A list with all the registered logger groups opens.
The current workgroup is indicated by an X.
3
Select a logger group for the measurement session.
Result: The selected group is now registered in the Commander as the
workgroup. In the main menu, the name of the workgroup is shown at the
bottom left of the display area.
Each logger group in the list has already been assigned its group mode (see
page 13).
Groups with an “L” before the name can only be read using “Lift & Shift”, i.e. all
the loggers in the group are collected and then read together.
Groups with a “P” before the name can only be read using “Patrol”, i.e. all the
loggers in the group remain in the shaft and are read on location individually.
The loggers of a group with an “N” before the name are networked together and
connected to a GSM-Box. These loggers can’t be read by a reading device but
send their data regularly to a FTP server.
32
Working in Easy mode
5.2 Programming the loggers
Introduction
Procedure
The loggers in the workgroup must be reprogrammed before each session. This means
that the Commander sends basic data for the session wirelessly to the loggers (e.g. the
measuring window).
To program the workgroup proceed as follows:
Step Description
1
In the main menu, select the Prepare loggers button.
Result: The workgroup is shown. The name of the group is at the very top of
the display, and all the loggers in the group are listed underneath.
2 Select the Prog. Group button.
Result: The next step is shown.
3
Switch off all the loggers in the group, i.e. place them “on their head” for about
three minutes.
As an aid, a three-minute countdown on the screen can be started with the
Start button.
Then select the OK button.
Result: The next step is shown.
33
(continued on the next page)
Working in Easy mode
Step Description
4
Switch on all the loggers in the group, i.e. place them “on their foot”.
Select the OK button to confirm.
Result: The next display provides information about the data used to program
the loggers.
(It is not possible to change this configuration data in Easy mode).
5 Select the Program button.
Result: The next display opens and the Commander automatically begins
transferring data to the loggers.
Possible sources of
error
The flashing antenna symbol on the bottom left of the display area indicates
that the data transfer is in progress. The left-hand window shows all the loggers
in the group already programmed. The right-hand window contains all the
loggers with which no contact has yet been possible.
The Stop button can be used to cancel programming at any time. It can be
recommenced with the Start button.
The procedure ends automatically once all the loggers in the group have been
successfully programmed.
The loggers are now ready to be installed for use on location.
Use the ESC button to return to the main menu.
From now on, do not place the loggers on their head because switching off
would cause them to lose their configuration data and they would need to be
reprogrammed.
If a logger could not be programmed, it may be because it was not in “Configuration
mode” at the time of programming, (see page 14) i.e. it had not been properly switched
off and switched back on 3 minutes later. It is also possible that the logger is not within
the wireless range of the Commander. The ideal distance between a logger and the
Commander is about one meter.
34
Working in Easy mode
5.3 Installing the loggers
Basics
Horizontal installation
Install the loggers of the workgroup in succession along the stretch of pipe. It is best to
fit them directly on the pipe. However, you can also attach the loggers to valve rods or
hydrants, for example, or any other position along the pipeline that is easily accessible.
There must be the best possible contact between the logger foot or the mounted
adapter (see below) and the pipe.
If the logger is attached to a valve rod, for example, make sure the surface is as flat as
possible. Clean the rod thoroughly (preferably with a wire brush).
Due to their powerful magnet, the loggers can also be attached horizontally to
ferromagnetic surfaces. You must however make sure the red mark on the logger is
facing upwards. Otherwise the internal tilt switch will switch the logger off after
3 minutes.
Loggers with the mark facing upwards are
switched on.
Loggers with the mark facing downwards are
switched off.
Special cases
If the logger cannot be attached anywhere directly, the accessories for the Sebalog N-3
set have various adapters.
If, for example, the surface of the valve rod is not flat, or not magnetic, unscrew the
magnet on the foot of the logger and fit the 20 mm or 42 mm valve rod adapter
(optionally available) instead.
When installing the logger on an underground hydrant, you can fit it on the valve rod or
on the side of the rod, depending on the height of the shaft. Use the magnetic angle
adapter, for example, for side mounting.
For underground hydrants with bayonet fittings, you can use the underground hydrant
adapter. Fit the adapter in the hydrant claw.
For plastic domestic pipes (water meter fittings), use the plastic fitting, if necessary in
combination with the angle adapter.

5.4 Reading out the measured data
After the loggers have been installed on location for at least one measuring day, the
recorded measured data can be read out with the Commander. The exact same group
mode (“Lift&Shift”/“Patrol”/”Network”) for which the workgroup was programmed is used.
Groups with an “L” before the name can only be read using “Lift & Shift”, i.e. all the
loggers in the group are collected and then read together.
Groups with a “P” before the name can only be read using “Patrol”, i.e. all the loggers in
the group remain in the shaft and are read on location individually.
The loggers of a group with an “N” before the name are networked together and
connected to a GSM-Box. These loggers can’t be read by a reading device but send
their data regularly to a FTP server.
37
Working in Easy mode
5.4.1 Reading out a “Lift&Shift” group
To read out the measured data in the loggers, proceed as follows:
Step Description
1
Collect up all the loggers of the group and place them next to the Commander.
Avoid placing the loggers on their head! The stored data would not be
lost if the loggers were switched off, but it would no longer be indicated
if a logger is in leak status or not (see page 14).
2 In the main menu of the Commander, select the Readout loggers button.
Result: The Commander and the loggers are connected. Data transfer begins
automatically. The antenna symbol in the bottom left of the display flashes.
As soon as the Commander detects a logger, it receives its measured data. The
corresponding logger switches from the right-hand to the left-hand window on
the screen.
The coloured background of the read data in the left-hand window reflects the
probability of a leak.
No colour … Leak probability low, leak threshold was not exceeded
Grey … Leak probability not available, logger in configuration mode
(was switched off during or after the measurement)
Other
colour
… Leak probability high! Leak threshold exceeded!
The colour reflects approximately the frequency of the leak
noise:
Blue
0 Hz
2,500 Hz
Yellow
If a logger’s comment is on a red background, this means that its battery is
weak.
3 The Stop button can be used to cancel reading at any time. It can be continued
with the Start button.
The procedure finishes automatically once the Commander has received and
saved the measured data from all the loggers in the group.
If a logger could not be read, it may have been switched off, not ready for
wireless operation or it was outside the Commander’s wireless range.
4
You can immediately view the data of a logger that has just been read. To do so,
select the left-hand window on the screen and then select the respective logger.
Result: The logger’s measured data is shown (see page 42).
Use the ESC button to return to the main menu.
38
Working in Easy mode
5.4.2 Reading out a “Patrol” group
To read out the measured data in the loggers, proceed as follows:
Step Description
1 In the main menu of the Commander, select the Patrol Loggers button.
Result: The Commander is ready to receive the measured data from the
individual loggers. The antenna symbol in the bottom left of the display flashes.
2
Move into the wireless range of each logger one after the other.
If the radio signals of the loggers are strong enough, the data can also be
collected while in the car, simply by driving past where the loggers are installed.
The Commander’s standard antenna can be replaced with the supplied vehicle
antenna to do this.
As soon as the Commander has detected a logger, the following message
appears on the screen:
Logger comment
Logger ID
Level/frequency of the
quietest noise in the
measuring period
The message has a coloured background. The colour shows straightaway
whether the programmed leak threshold has been exceeded or not during the
measuring period.
• Yellow … Attention! Leak threshold exceeded!
• Blue ... Leak threshold not exceeded
There is an acoustic signal along with the message:
• Long tone ... Attention! Leak!
• Short tone … No leak
As standard, the tone sounds each time a logger is detected. It can be
deactivated in the system settings of Professional mode (see page 27).
If the displayed message contains a battery symbol, this means the battery of
the particular logger is weak.
If the displayed message contains a clock symbol, this means the logger’s
internal clock differs from the system time of the reading device by more than
30 minutes. The logger group concerned should be reprogrammed. The logger’s
clock is synchronised with that of the Commander. It is only possible to change
the time of individual loggers in Professional mode.
39
(continued on the next page)
Working in Easy mode
Step Description
The detected logger switches from the right-hand to the left-hand window on the
Commander screen. The coloured background of the read data reflects the
probability of a leak.
No colour … Leak probability low,
leak threshold was not exceeded
Grey … Leak probability not available,
logger in config. mode,
(was switched off during or after the measurement)
Other colour … Leak probability high!
Leak threshold exceeded!
The colour reflects approximately the frequency of the
leak noise:
Blue
0 Hz
2,500 Hz
Yellow
If a logger’s comment is on a red background, this means its battery is weak.
3 The Stop and Start buttons can be used to cancel and continue reading at any
time.
The procedure finishes automatically once the Commander has received and
saved the measured data from all the loggers in the group.
During “Patrolling”, the complete measured data set is only transferred
to the Commander from loggers in leak status (see page 14). To save
power, if the quietest noise in a measurement is below the programmed
leak threshold, the loggers will only send a small packet to the
Commander, with the level and frequency of this noise. If necessary, the
complete measured data of these loggers can be called up using single
interrogation in Professional mode (see page 54).
If a logger could not be read, it may have been switched off, not ready for
wireless operation or it was outside the Commander’s wireless range.
4
You can immediately view the data of a logger that has just been read. To do so,
select the respective logger in the left-hand window on the screen.
Result: The logger’s measured data is shown (see page 42). Use the ESC
button to return to the main menu.
