Thermocouple
NIST ITS-90 reference functions (Monograph 175) with cold-junction compensation. Inverse uses Newton–Raphson on the forward polynomial.

Ice bath = 0 °C. If the meter already compensates, leave CJC at the reference it uses (often 0) or convert uncompensated millivolts with the actual cold-junction temperature.
