Converts a voltage read from a thermocouple into a temperature.

National Instruments has chosen thermocouple polynomial expressions that are valid only for particular temperature ranges (given in the VI diagram). These polynomials come from the NIST Monograph 175.

If you wish to use a different conversion formula, you can edit this VI and enter your own equation into the appropriate formula node.
