Q. What thermocouple types are supported by the F3-08THM-n?
A. E, J, K, R, S, T, 0-50mV, and 0-100mV

Q. I connected a thermocouple to the F3-08THM-n but the temperature reading is way off or it reads burnout, what's wrong?
A. Make sure that the thermcouple type that you are using matches the part number you are using. F4-08THM-J should be used with a J type thermocouple.

Q.Can I field calibrate my F3-08THM-n?
A. There are no field adjustments for this module but you can use ladder logic to add or subtract a calibration factor.

Q. How can I verify the module is functioning correctly?
A. Thermocouple calibrator. Not all thermocouple calibrators will function with our module. To detect thermocouple burnout, we send balanced currents down each leg of the thermocouple wire, most thermocouple calibrators CANNOT handle this current pulse. We use an NIST traceable thermocouple calibrator - ALTEK Model 422.

Q. How much error will thermocouple extension wire introduce?
A. Thermocouple extension wire has a limit of error from 1.7°C to 2.2°C depending on the type wire. This error can be removed by subtracting the error from your reading in ladder logic.
