Additional Features
Cold Junction Heater
The FlightDaq-TL, when combined with the Smart Lemo®, has a built-in
thermocouple cold junction heater which is used to check that the polarity of the
thermocouple is correct. The heater is enabled via the web server and will apply
a current to a heating resistor bonded to the cold junction for 15 seconds. The
user can then determine if the polarity of the thermocouple is correct.
Hot Junction Polarity Reversal
As part of the channel configuration, the polarity of the hot junction can be
reversed if it is found to be incorrect by the above test.
