I am interfacing K-type thermocouple with cold junction compensation. Is below is right way of cold junction compensation:
1. measure voltage generated by TC. Now use look-up table as given in:

to get the temperature corresponding to that voltage.
2. Measure cold junction temperature.
3. Add both temperature to get final absolute reading.
