Warning
Permanent damage may be done to the thermometer if the power supply connections are not done correctly.
Only use the supplied 6VDC power supply module to operate the HHTFO; please note that this module will
not charge any internal batteries.
This product does not contain any user-serviceable parts. Opening this precision instrument will void its
warranty and disturb its factory calibration. Always seek servicing from an authorized Omega Engineering
service depot.
Fiber optic probes are fragile, and will break if the bending radius becomes less than ~1cm, even temporarily.
Probe breakages are not covered under the standard Omega warranty. Do not bend the last one cm of the
probes!

NTRODUCTION
Congratulations on the purchase of your HHTFO Series thermometer product! Your new temperature-
sensing instrument will soon 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 HHTFO Series of products gives access to reliable measurements, but 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 elements.
The thermometer is packaged in a small hand-held package, which is ideally suited for portable applications.
This model does not feature an analog output option; the Omega model FOB is recommended if this option is
required.
The standard configuration is offered with an RS-232 interface. In addition, a large LCD graphical display
makes it easy to see the temperature for one channel supported by the HHTFO, either in Celsius (oC) or in
Fahrenheit (oF), even in dark areas (by activating the back light); it also includes a powerful but simple
keypad that gives the user access to all built-in features; these standard features are great for laboratory and
field applications. Furthermore, a convenient data-logging feature is included; logging is done directly to a
standard MMC or SD flash card.
An optional software package, FOB100-SOFT, makes your thermometer even more useful. It is easy to use,
and allows the user to easily monitor even multiple thermometers at the same time, and to perform easy data
logging. PC compatible.

Before using your HHTFO thermometer, check the box content to be sure all items have been included. Your
package should normally contain:
• HHTFO signal conditioner unit
• Power supply module (universal input: 100-240VAC, 50/60Hz; output: 6VDC). Note: this is not a battery
charger.
• Short extension cord and mating sleeve (should be used to minimize damages to the connector at the
HHTFO interface)
• User manual (this manual)
• Calibration Certificate.
Options:
• Fiber optic temperature sensor probes
• Fiber optic extension cables
• Fiber optic coupling
• RS-232C interface cable
• Battery charger, with 4 AA batteries (Ni-Cd or Ni-MH) (universal input: 100-240VAC, 50/60Hz)
• SD memory card (various capacity, up to 1Gbyte)
• SD card reader (USB interface)
• USB serial adapter cable
• FOB100-SOFT software package (CD)
• Carrying case, for HHTFO and accessories.
Make sure all listed items have been received and are in good condition. Note any evidence of rough
handling in transit; immediately report any damage to the shipping agent. Should a part be missing or

3 Q
The best way to familiarize you with your new HHTFO thermometer is, of course, to use it! This chapter
shows you how to prepare your unit and do some initial measurements. The detailed instructions are given in
the next Chapter.
Your new HHTFO comes calibrated and ready to use. If the unit has not been used already, install fresh AA
alkaline or rechargeable batteries. This figure shows the main view of the HHTFO, along with the top and
bottom views.

You will find the battery access port at the bottom of the HHTFO. Insert 4 fresh “AA” batteries, or connect the
supplied 6VDC universal power supply. If using rechargeable batteries, make sure they are completely
charged. The following illustration shows the proper orientation of the 4 AA batteries:
