1.1 General Information
The Industrial BraggMETER DI is a continuous swept
laser scanning interrogator for fiber Bragg grating (FBG)
sensors. It includes a traceable wavelength reference
that provides continuous calibration to ensure system
accuracy over long term operation. The high dynamic
range and high output power allow high resolution to be
attained even for long fiber leads and lossy connections.
Multiple sensors can be connected in series in each opti
cal fiber, which in combination with the eight optical chan
nels with parallel acquisition for the FS22 - Industrial
BraggMETER DI, makes it particularly suitable for large
scale sensing networks, acquiring a large number of sen
sors simultaneously, providing 1000 S/s acquisition rates
with sub picometer resolution.
The BraggMETER is available in Standard and Rackmountable format. This Manual applies to the following

Regulatory and Certification Considerations
2.2 Laser Safety
The FS22 - Industrial BraggMETER DI interrogator con
tains a laser in its core. A laser is a light source that can
be dangerous to people exposed to it. Even low power
lasers can be hazardous to a person's eyesight. The
coherence and low divergence of laser light means that it
can be focused by the eye into an extremely small spot
on the retina, resulting in localized burning and perma
nent damage.
The lasers are classified by wavelength and maximum
output power into the several safety classes: Class 1,
Class 1M, Class 2, Class 2M, Class 3R and Class 4.
2.2.1 Symbols
Warning symbol Class 1 Laser symbol
2.2.2 Class 1 Laser
The FS22 - Industrial BraggMETER DI is a class 1 laser
product:
«Any laser or laser system containing a laser that cannot
emit laser radiation at levels that are known to cause eye
or skin injury during normal operation.»
FS22 DI A4248-6.0 HBM: public 11
Regulatory and Certification Considerations
It is safe under all conditions of normal use. No safety
requirements are needed to use Class 1 laser devices.
This product contains a laser within an enclosure that
prevents exposure to the radiation and that cannot be
opened without shutting down the laser.
2.2.3 General Precautions Considerations
Everyone who uses a laser equipment should be aware
of the risks.
The laser radiation is not visible to the human eye but it
can damage user's eyesight.
The laser is enabled when the interrogator is turned on.
Users should never put their eyes at the level of the hori
zontal plane of the optical adapters of the interrogator or
uncovered optical connectors.
Adequate eye protection should always be required if
there is a significant risk for eye injury.
When an optical channel is not in use (no optical connec
tor plugged to the interrogator), a proper connector cap
must be used.
The optical connectors are subjected to maintenance
and/or inspection. Please refer to section 4.3.1 for main
tenance procedure.
Do not attempt to open or repair a malfunction interroga
tor. It must be returned to HBM FiberSensing for repair
and calibration.

rogator connect the supplied power adaptor to a 100 240 V power line, or an 11-36 VDC power line directly, to
the interrogator power connector (number 3 in Fig. 3.1).
To start the Industrial BraggMETER DI Rack-Mountable
interrogator connect the supplied power cable from a
100 - 240 V power line to the interrogator (number 4 in
Fig. 3.2) and turn on the safety power button (number 6
in Fig. 3.2).
The interrogator must be used with a dedicated power
supply source and not shared with other equipment.
3.2.2 Optical Connectors
The Industrial BraggMETER DI can be purchased either
with FC/APC, or SC/APC optical connectors. Number 1
in Fig. 3.1 and number 3 in Fig. 3.2 exemplifies FC/APC
connectors.
Attention should be paid to the cleaning of the optical
connectors. A dirty connector can compromise the mea
surement and will degrade the performance of the inter
rogator. It is advisable to frequently clean the connectors
using appropriate tools.
FS22 - Industrial BraggMETER DI can have one, four or
eight optical channels in parallel.

3.3 Switching On
Pressing the “ON/OFF" button (number 2 in Fig. 3.1 or
number 1 in Fig. 3.2) will start the interrogator. The STA
TUS LED (number 5 in Fig. 3.1 or number 2 in Fig. 3.2)
will start blinking at 2 Hz. After approximately 10 seconds
it will start blinking at 1 Hz. This means that the inter
rogator is already on and responsive, but the optoelec
tronic module is still warming up. After approximately
60 seconds it should stay on permanently. This means
that the interrogator is able to measure.

3.5.2 Interrogator IP Address
Changing IP
The interrogator default network properties are
10.0.0.150:255.0.0.0:0.0.0.0. These can be changed
using the SCPI commands.
The interrogator proceeds with a change of these proper
ties when :SYST:IPAD:N.N.N.N:N.N.N.N:N.N.N.N com
mand is sent. See section 5.1.3 “System commands”
under IP Address for further details.
Information
The definition of the network properties shall comprise
three digits to define each number – e.g.,
010.000.000.150:255.000.000.000:000.000.000.000 –.
Default IP Address
The default network properties of the interrogator are
"10.0.0.150:255.0.0.0:0.0.0.0". These default network
properties cannot be changed.
Resetting IP to Default
If by any chance there is the need to physically change
the IP address of the interrogator, press the "ON/OFF"
button for more than 10 seconds to reset the interrogator.
When the button is being pressed for 10 seconds the
POWER LED blinks 3 times and goes OFF. The "ON/
OFF" button can then be released and the IP Address
will be reset.
This procedure will restart the interrogator automatically.

Information
The interrogator default network properties are
"10.0.0.150:255.0.0.0:0.0.0.0".
3.5.3 Synchronization
In order to achieve synchronous measurements between
different devices the NTP (Network Time Protocol) syn
chronization via Ethernet must be used.
Each optical Interrogator can synchronize its internal
clock with an NTP server. It is possible to achieve accu
racies of 1ms or higher, depending on whether or not a
dedicated NTP server is being used.
Further information about NTP can be found at
http://www.ntp.org
24 A4248-6.0 HBM: public FS22 DI
Single interrogator
Multiple
interrogators
Operation
Measuring systems typology
A measurement system can be as simple as a single
interrogator or a bit more complex with combined inter
rogators with the same or different sampling rates, and
interrogators combined with other equipment.
For the usage of a single interrogator no special synchro
nization is needed.
BraggMONITOR DI software can only operate one inter
rogator at a time. If an NTP server is running on the
same PC as the BraggMONITOR DI, the interrogator
internal clock – hence BraggMONITOR DI – will sync.
If more than one interrogator is used, synchronization
becomes important and if an NTP server is running the
equipment will start synching as soon as a first communi
cation from the server is received.
Fig. 3.10
Hybrid
A hybrid measurement system is a system composed by
different equipment types and technologies that can be
operated with different sampling rates. Taking the exam
ple of HBM families a hybrid system could be a combina
tion of Interrogators with QuantumX.
FS22 DI A4248-6.0 HBM: public 25
Operation
Fig. 3.11
Synchronization is again of extreme importance in such
systems. When an NTP server is running the Interrogator
will start synching as soon as a first communication from
the server is received.
For details on the other equipment please refer to their
respective user manuals.
Synchronization process
Each interrogator synchronizes its internal clock with the
NTP server. Upon starting, all devices and the NTP
server need some settling time to achieve the best syn
chronism possible.
The following features for NTP synchronization are avail
able:
Number of devices to
be synchronized

Operation
Synchronization
settling time
Synchronization
master
Up to 30 min during first start,
up to 2 min during restart
External SyncMaster, e.g. PC
For a good synchronization, the dedicated NTP server
should run continuously. The accuracy is described by
the two values:
S Offset: average deviation from time server
S Jitter: typical variation range of the offset value
The clock synchronization is classified using the following
offset intervals:
S <500 μs: excellent
S <1 ms: very good
S <2 ms: good
S <5 ms: acceptable
S <10ms: poor
S >10ms: not acceptable
A successful NTP Sync is achieved if the offset between
the internal clock of the device and the NTP server is
below 5ms.
The quality of the NTP synchronization can be queried
using the SCPI commands (please refer to section “Syn
chronization” on page 53 for further details).
