20 mA analog output options are self-powered interfaces (by opposition to loop-powered interfaces), and thus do not require any external supply. 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. -
Page 4: Introduction
NTRODUCTION Congratulations on the purchase of your FOB100 Series thermometer product! Your new temperature sensing system 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. -

Page 10: Using The Temperature Probes
SING THE EMPERATURE ROBES 4.1 Caution Each time you connect a temperature probe to the unit, the probe optical connector should be cleaned beforehand. Otherwise, particles of grease or dirt may obstruct the device internal connector and affect the measurements by completely blocking the signal or by generating too much attenuation when using a long fiber length. -

Warning: Solvents and fuel oils can cause problems for silicone rubber. Omega also manufactures probes that have their tips made of epoxy. Just like silicone, epoxy resin is resistant to a large number of chemical aggressors, strong acids or alkali may damage it, especially at high temperature and/or if used for extended periods of time. -

Page 23: Viewing Temperature Data
When logging temperatures for a very long time, one needs to note that a standard Excel sheet is limited to 65535 lines. If this limit is reached (65000 lines), the logging process will close the current data-logging file, and will open a new one, with the same name but with “_1” appended to the file name, and so on (“_2” …), until the application is stopped or your disk becomes full. - Page 24 Adjust the “Refresh Rate” (minimum is 0.2 sec) and Min / Max to suit your viewing needs. Note that the setting of curve colors and other parameters must be done in the “System Configuration” window pane. Up to 64 trends can be displayed. 7.3.2.2 Displaying analog thermometers Click the “Thermo”...

Page 25: The Fob100 Console
The console, which can be invoked through the Window and then Open Console from FOB100-SOFT main window menu bar, is useful to manage each Omega thermometer in details. Take note that the console can only be open when no temperature acquisition is taking place. It can be useful also to understand problems and malfunctions that a module may exhibit. -
Page 26: Console Help Menu
Before sending commands and receiving information from a specific module, it is necessary to select the instrument you want to interrogate. Please note that only ONE instrument can be selected at a time; if the same command is to be sent to all thermometers, then, it is necessary to repeat the command for each individual module. -
