TARTED
Your FOM-L201/H201 series temperature-sensing instruments allow you to take full advantage of the benefits inherent to
fiber optic sensing technology. It offers accurate and reliable temperature measurements, combined with extraordinary
insensitivity to EMI/RFI, high voltage insulation and disturbance free sensing due to the non-electrical nature of the sensor
element used.
Not only does the FOM-L201/H201 family of products gives access to reliable measurements, it also offers a simple user
interface that makes the technology easy to use. Moreover, no special calibration is required when changing the fiber optic
sensor probes.
The FOM-L201 and FOM-/H201 are very similar instruments; the main difference between the two is that the FOM-H201
includes an internal rechargeable battery, which should last about 10 hours of continuous use. Please note that the FOML201 could also be converted easily into a portable instrument by simply connecting the unit to an external USB power
battery bank, available on the open market.
When a specification or feature is applicable to both the FOM-L201 and the FOM-H201, the instrument is referred as “FOM-
L201/H201” in this user guide.
The thermometer is packaged in a small package, which is ideally suited for laboratory and industrial applications.
The unit is fitted with a micro-USB connector ( ). This interface allows for powering the unit as well as for all data
transfer, to or from a Windows computer. The transfer protocol is a fast serial scheme, a standard in the industry. If you
have the FOM-H201 model, the internal battery will be charged whenever the USB port is connected to a power source
(such as your computer or wall-USB power supply.
This thermometer includes the latest developments in fiber optic temperature measurement technologies. Most types of
GaAs-based probes now available on the market are supported, even probes manufactured by Omega’ competitors. It will
also interface with and read marginal probes, or probes with dirty connectors, and so forth. It will give you years of excellent
service.
The Omega Fiber Optic Sensing software package is an excellent complement to your thermometer. This Windows
software allows the user to configure the FOM-L201/H201more easily than using the few keys available on the instrument
itself. It should be noted that some functions are programmable only from Omega Fiber Optic Sensing.
Temperature logging can be performed in two ways:
1- Directly in the instrument, using a user supplied microSD memory card (in theory, up to 2 TB)
2- With Omega Fiber Optic Sensing. In this case, logging can be done concurrently from 6 instruments (up to 64
channels)
3- Logging rate from one sample per second
4- Both logging methods can be used simultaneously.
A serial RS-485 communication port is available; this could be useful for Modbus communication (industrial applications).
An optional analog output module is available. It features 8 channels and can be programmed to operate with 0-10 V or 4-
20 mA outputs, and the outputs are completely programmable (any analog output can be assigned to any optical channel
or can be assigned to the minimum or maximum value of any combination of optical channels).

2.2 Calibration
Your FOM-L201/H201thermometer comes factory-calibrated. Experience has shown that re-calibration is not required over
the whole product life; however, if your ISO company rules state that an annual re-calibration is required, then it is your
responsibility to comply with those rules. For laboratory applications, a new calibration is standard every 12 months or
whenever performance verification indicates that calibration is necessary; NIST traceable calibration certificates are
available. All calibrations are performed at the factory. Contact your Omega Representative for further information.

4 QUICK Introduction
The best way to familiarize yourself with your new FOM-L201/H201 instrument is, of course, to use it! This chapter shows
you to prepare your unit and do some initial measurements. The detailed instructions are given in the next Chapter.
Your new FOM-L201/H201comes calibrated and ready to use. This figure shows the main view of the monitor, along with
the top and side (where the electrical connections are available) views.
For the FOM-H201, you may need to connect it to a power source for a few hours to make sure the internal battery has
enough charge to use it without power connection.

Information: The FOM-H201 battery charging status is not indicated on the above drawing.
4.1 Making your first measurements
4.1.1 Using the FOM-L201/H201
To make your first temperature measurements, do as follows:
• Remove the dust cap on the optical connectors of the FOM-L201/H201 (located on the top of the monitor).
• Remove the dust cap on the probe connectors.
• Insert each probe connector into a sensor connector on the monitor. Make sure the two mating parts are properly
aligned and twist the connector clockwise to fasten it securely. Notice: Do not apply force on this connector!
• Turn your FOM-L201/H201on by pressing the ON button for at least one second. After a few seconds, a “splash”
screen will display some information such as firmware version, calibration date, etc. Then the temperature is
immediately displayed, for up to 8 channels.
• Place a sensor tip on a warmer surface (such as your hand): you can observe the temperature variation on the
display.
• You can power it down by briefly pressing again this key.

4.1.2 Logging temperature data on the microSD card
A microSD memory card slot, where a SD card ( ) can be inserted to allow for in-instrument temperature logging1.
Reading the SD card content can be done by removing the card from the instrument and reading it with a USB adapter on
a PC computer. Data files can also be transferred to a PC using Omega Fiber Optic Sensing; however, this could be a
long process for large files. When removing the card, it is suggested to stop the logging process by powering down the
instrument (this is not mandatory but would be safer).
See section 5.3 for more information about reading back data from the microSD card.

It is highly recommended to get your microSD memory cards ( ) from Omega, even if they are relatively expensive.
The Omega cards feature a wide temperature range and are ruggedized, for demanding industrial applications.

5 FOM-L201/H201THERMOMETER HARDWARE REFERENCE
5.1 Display description
The display can show 4 different screen contents. You can navigate from one to the next by pressing the
“Menu” key.
1- The default screen is the Temperature screen, where up to 8 temperature values are displayed, as shown here:
a. A double arrow is displayed for any channel reading where an offset has been programmed for that channel
(as shown for channel # 1 above)
2- The Percentage screen, where the power level of each sensor is given. Normally, for a healthy probe, the reading
should be 100%. See section 5.4 for information on how to interpret this “%” reading.
3- The Enable screen. This allows you to enable or disable a specific channel. Normally all channels are enabled,
but if you want fast refresh rates from one or a few probes, it is highly suggested to disable any unused channels2.
4- The Setup screen. To move through the screen, you can use the “OK” button to move from one field to the next
and use the 2 arrow keys to change the flashing parameter value. This can be used to configure the following
parameters:
a. Date and time
Notice: The FOM-L201/H201 will lose its date and time information after about 10 days if not
turned on while being connected to a power source. Even the FOM-H201 should be turned on
from time to time to avoid losing its date and time.
b. Logging status, information only. To enable or disable logging, press the “OK” button when you are not in
this Setup menu.
c. Logging rate (on microSD card). Note: Independently, Omega Fiber Optic Sensing can also log
temperatures, and it can be set to a different logging rate.
d. AGC, ON or OFF. For best speed, this should be OFF. The ON position is recommended for installations
where you are dealing with probe weaker signals, such as when using extension cables and feedthroughs
(typically for transformer applications).
e. Hold, 0 to 9. This indicates the number of “holds” since the last good reading. Normally, a value of “0”
should be appropriate, unless you are using probes with weak signal, in which case it could avoid a probe
from alternating from “no reading” to “reading”. In other words, this represents the number of reading cycles
the thermometer will do before abdicating.
2
The FOM series scans continuously all enabled channels in a sequential manner. The acquisition time for each channel
is about 0.1 (fixed gain, AGC off) to 0.4 second (AGC on), which means that it takes about 1 to 4 seconds to refresh all
channels. If you disable any unused channels, then the overall refresh rate will be faster.
Page 14

UNRESTRICTED
The setup screen is shown here:
The following parameters cannot be set from the FOM-L201/H201panel, you must use the Omega Fiber Optic Sensing
software to set them.
1- RS-485 serial port and Modbus parameters; 2- Analog
output parameters; 3- Channel naming.
5.1.1 FOM-H201 battery charging status
The FOM-H201 panel includes a LED indicator that can take 2 states:
• Yellow when the battery is being charged (not yet fully charged)
• Green when fully charged.
5.2 Modbus port configuration
The serial RS-485 port found on the side of the FOM-L201/H201instrument is intended to be used as a Modbus slave port.
You can configure its parameters (baud rate, parity, etc.) with Omega Fiber Optic Sensing. When using this port, be careful
with grounding, as this port is non-insulated. The port can be configured either as a 2W configuration (half-duplex, 2 wires)
or as a 4W configuration (full-duplex, 4 wires).
The mating connector (not included with the instrument) is Phoenix part # 1827622, or Digikey part # 2778837-ND. Contact
Omega for more information.
The following guidelines should be followed when wiring the Phoenix terminal blocks:
• Current and voltage should be limited to 5 A3 and 240 VAC
• Wire gauge range is 12-30 AWG (0.2 to 2.5 mm)
• Torque on screws should be 0.5 to 0.6 Nm (4.4 to 5.3 Lb-In).
Recommendation: As this port is not electrically insulated inside the FOM, it is strongly suggested to use an insulated
interface to connect the Modbus communication to a PC computer. Omega recommends the use of Model USOPTL4,
available from B&B Electronics (web site: http://www.bbelec.com/USOPTL4).
The following drawings show examples of typical wirings for a Modbus communication scheme (4W and 2W).

5.3 How to access the logged data
To log temperature data, a microSD card must be inserted in the card slot. This card must be formatted in FAT or exFAT,
and up to 2 TB (in theory) is supported. When removing the card, it is suggested to stop the logging process by pressing
the “OK” button. Each time a new log is started, a new file is generated with a set file name (YYMMDD_HHMMSS.csv),
with tab delimitation; the date and time used are those current when the file is generated.
To read the logged data, you have two possibilities:
• You must remove the card from the FOM-L201/H201and to read it with a PC using an appropriate microSD card
reader. You should configure your Excel application, so Excel is automatically invoked when you open a .csv file.
• Data files stored in the microSD card can be downloaded using the Omega Fiber Optic Sensing software. See
Section 6.4 for more information. Please note that the file that is currently being open for data logging cannot be
downloaded; you must first stop the acquisition and then do the download. Notice: Downloading large file can be
time consuming.
Information: -302 means that this channel is disabled and -303 means that no probe was detected for that channel.
Here is an example of a .csv file.
5.4 Analog output module
The optional analog output module is easy to use; it is also very flexible. To configure it, you will need to run the Omega
Fiber Optic Sensing software; see next chapter. Here are some features, with some comments:
• Voltage outputs. You can select 0-10 V. Please note that this requires a ground connection, so be careful with
ground loops, which can easily fool the voltage values.
• Current outputs. 4-20 mA is the industry norm. This is a better choice for industrial applications, as it is ground
isolated (no ground loops).
• Any output is completely programmable:
o It is not hard-assigned to any specific optical channel
o One output can reflect the temperature values of many optical channels (e.g., minimum or maximum
temperature read from many channels)
o For each output, you can define the low and high temperatures (the difference between these two would
be the “span”
o With “Error Style”, you can define the behavior of the output if no temperature is read for that output.
Page 17
17
UNRESTRICTED
The following figure shows the Analog Outputs tab, from Omega Fiber Optic Sensing. You are referred to the next chapter
(Omega Fiber Optic Sensing) for clarifications on how to set the various parameters.
Notice: This module is not plug-and-play: it must be installed (plugged in to the FOM) when the instrument is powered off,
otherwise it will not be initialized correctly, and it will not work.
5.5 Interpretation of “%” results
The FOM-L201/H201system is fitted with an algorithm that gives an evaluation about probe signal strength or signal quality
index. This is expressed as a percentage value, with 100% being the highest score, and 0% meaning no signal (no probe
or broken probe). The % reading of probes can be obtained in two ways:
1- Form the instrument panel, by clicking the “Menu” button once.
2- With Omega Fiber Optic Sensing, by selecting the DATA tab. See section 6.2.
Dirty connectors will contribute to lower probe strength; always assure that all fiber connections are clean before evaluating
probe performance.
For installations where extension cables and/or feedthroughs, it is highly recommended to turn on the “AGC” auto-gain
feature. You can control the AGC setting either from the instrument panel or from Omega Fiber Optic Sensing.
Note: In Omega Fiber Optic Sensing, the “no-AGC” mode is called “Fixed time”, in the General tab. Be advised that having
the AGC feature on will slow the acquisition time; thus, for fast acquisition it is recommended to turn off the AGC feature.
Based on experience, a power value of 65% or more is considered as being satisfactory.
Notice: These values are approximate and may change slightly from instrument to instrument.
6 OMEGA FIBER OPTIC SENSING SOFTWARE DESCRIPTION
Omega Fiber Optic Sensing is particularly interesting for FOM-L201/H201 users as it provides a convenient complement
to how instrument parameters are controlled and how temperature data is acquired. It offers a friendlier procedure to load
various parameters, such as optical channel parameters that would otherwise require being set by hand using the
instrument panel. The goals and purposes of this software packages are as follows:
Display temperature information

• Can provide results in graphical form
• Can log temperatures to a Windows file, independently from the logging feature the instrument itself
• Initialize and manage the optical channel and associated control parameters
• You can work with “virtual” instruments, i.e., you can develop instrument configurations without having a physical
instrument connected to your PC • It allows for transferring configurations between instruments • And more.
6.1 Installation and initial operation
6.1.1.1 Installing the USB serial driver
When installing the Omega Fiber Optic Sensing software, a serial driver (FTDI) that is required to connect your instrument
via a USB link ( ) will be installed; this installation is normally done automatically by the installation process. If this
driver is already installed (for example, when upgrading the Omega Fiber Optic Sensing software), then this driver
installation will not take place.
6.1.1.2 Software installation
Get a copy of Omega Fiber Optic Sensing from Omega, at https://www.omega.com; you will need to request access online.
You can also write an email to temperature@omega.com. Simply run this setup program (no unzipping is required).
Windows-10 users: If you get this left window, below, you need to click on “More info”. Then, in the next window (shown
at right), you need to click “Run anyway”.
I
Notice: To reinstall the software, or install a new version, you will need to first uninstall the older version. This must be
done by using the “Programs and Features”, found in Windows Control Panel.
You get this window, shown below (1st picture). Click Next. Here you can accept or change the location where Omega Fiber
Optic Sensing will be installed (2nd picture). Click Next. Click Install to start the installation process.

UNRESTRICTED
No internet connection is normally required to perform the Omega Fiber Optic Sensing installation; one exception could
be that your NET Framework 4.7.2 tool needs to be upgraded. The current version of Omega Fiber Optic Sensing has
been fully tested with Windows-10.
Connect your instruments (up to 6) to your PC. Each instrument must have its own USB port ( ); you can use a USB
hub if necessary.
You get this window if one FOM-L201/H201is already connected:
The instrument can basically operate in two modes of operation:
• Data mode, where temperature values can be displayed in number or trend form. This will show temperatures for
up to 6 connected instruments. If you do data logging, all temperatures from all instruments will be logged in a
single file.
• Configuration mode: here you can configure your selected instrument (only one at a time).
These 2 modes of operation are explained below.
Page 20

UNRESTRICTED
6.2 Data mode (temperature acquisition)
By clicking on DATA (from the top menu bar, at left) as shown above, your instrument will be in data mode whereby it will
continuously acquire temperature data from all connected instruments. This is shown here (6-channel instrument, with
only 1 probe):
This window shows all temperatures in number format (oC or oF). If select from the menu either MIN/MAX or TRENDS
(graphics), you can see the same data presented in different ways including in graphical form.
6.2.1 Logging data to a PC file
The data mode allows also to log data to a PC file. Click the Start Logging button at the bottom of the window, and an open
file dialog will open and press Data Logs tab to access previous files, as shown here:
The file is a .csv that can easily be read by Excel, as shown here:
Page 21

UNRESTRICTED
6.3 Device configuration mode
Click on the instrument serial number of the instrument you wish to configure (the list of instruments is in the left pane of
this window). Then click on CONFIGURE from the menu bar; you will get:
After a few seconds, this Configuration window is populated, and you can change any parameters you want (some fields,
in light grey, are for information only and are not changeable); do not forget to click the
“Write/Save”, button, to save your new parameters to the instrument.
Please note that this window works with only one instrument at a time, by opposition to the Display window where all
temperatures from all connected instruments can be displayed.
As part of configuring your instrument, you can select other tabs, to configure other parameters, such as the analog outputs
(if this option is available on your instrument). The most important are described here; for the others, you are invited to
click on the various buttons and learn what they can do for you.
6.3.1 SETUP tab
As shown in the window below, here you can set:
1- Acquisition Mode (AGC). For best speed, this should be Fixed. The AGC selection is recommended for
installations where you are dealing with probe with weaker signals, such as when using extension cables and
feedthroughs (typically for transformer applications).
2- Hold Last Good. This indicates the number of “holds” since the last good reading. Normally, a value of “0” should
be appropriate, unless you are using probes with weak signal, in which case it could avoid a probe from alternating
from “no reading” to “reading”. In other words, this represents the number of reading cycles the thermometer will
do before abdicating.
3- Internal logging and logging rate. You need a microSD card in your instrument to be able to log into your
instrument.
4- Date and time update. You can update the time/date of your instrument here. The FOM-L201/H201 will lose its
date and time information after about 10 days if not turned on while being connected to a USB power source.

6.3.2 CHANNELS tab
Here, you can do the following:
• Give alphanumeric names to optical channels
• Enable and disable optical channels. It may be useful to disable unused channels, to improve temperature update
speed
• Enabling and disabling logging on the microSD card, independently for each channel
• Finally, you can force an offset for each channel. Please note that forcing an offset on a channel will defeat the
instrument calibration.
6.3.3 COMMUNICATION tab
Here you can select which protocol you want to enable on the serial RS-485 port. Currently, 4 choices are available:
1- None
2- Modbus. Chapter 7 includes a description of the Modbus registers
3- IEC 60870-5-101. See T301 user guide for more information on this protocol (document User Guide)
4- DNP 3.0. See T301 user guide for more information on this protocol.
Once you have selected a protocol, you can change the baud rate, parity, stop bits and node address to communicate with
your master device.

6.3.4 ANALOG OUTPUTS tab
Analog output parameters can be set here. Refer to section 5.4 for more information for hints on how to set these outputs.
Take note that the analog output module is an option on the FOM, so this setting will be only useful if that option is present
on your FOM-L201/H201.
6.3.5 Importing / Exporting instrument configurations
Importing and exporting configurations are easy to do. If you place your mouse over the instrument name in the left pane,
you will get the information shown here, and then by right clicking, you will get what is shown at right:
From here, you can click on Import or Export Configs. The Export function can be useful if you intend to configure multiple
instruments with the same configuration.
6.4 Downloading data files
You can download data from you instrument by clicking on the DATA LOGS tab. Select a file and click the Download File
button.
From the same window, one can also delete files stored in the instrument microSD.

6.5 Offline configurations
Omega Fiber Optic Sensing allows you to create offline configurations, i.e., configurations for instruments that are not
connected to your PC (these can also be called virtual configurations). You can then save this configuration file, which
could be later uploaded to a real instrument. It might be a good idea to call these virtual configurations by project number
or name; when they will be uploaded to a real instrument later, then its name will change to the instrument actual serial
number.
Click on the “Add Device” button found at the bottom left of the window. The following small window will open:
Fill the text boxes with values that your new instrument should have and click “Save”. From this point, you can continue to
configure it as if this instrument were a real one. When you are done with your configuration, do not forget to click on
“Write/Save”.
6.6 Firmware upgrade
If an upgrade is required on your instrument, please contact Omega to get a new firmware code file (with extension *.hex).
Once you have this file, follow this procedure:
• Download from the web the following ST upgrade software:https://www.st.com/en/developmenttools/flasher-
stm32.html). Install this program and run it to get to the first screen shown below.
• You will need to know the serial port number used by your instrument to connect through the USB
link. This is best done by invoking the Windows’ Device Manager utility, as shown here:
In this example, as shown above, it would be COM8.
• To force the instrument to be in “upgrade” mode, you will now need to do the following:
o Make sure the instrument is turned off
o While pressing simultaneously both UP and DOWN arrow keys, turn on the power to the instrument.
Important: hold down these 2 keys until the progress bar shown by the ST utility has started!
o The instrument is now in reprogramming mode
• Make sure the Port Name and Baud rate (115,200) are correctly set as shown in the first figure below. Click Next,
to get to the second figure. Click Next again, to get to the third figure.

UNRESTRICTED
• Click Next again, to get the fourth figure, below. Here, you need to select “Download to device” and select your
firmware code file (*.hex), by clicking on the “. . .”, as shown by the red circle. Click Next. The fifth figure will show
up with a download progress bar. You can now stop pressing the two arrow keys. The download process with take
about one minute to complete, at which point the progress bar will turn green, as shown in figure sixth.
• To get your instrument out of the firmware upgrade mode, turn the instrument off and after a few seconds turn it on
again.
•
The upgrade process is now finished.
