A J-type thermocouple with an ice-reference junction showed a reading of 22 mV. After the experiment, it was found that the actual temperature of the reference junction is 4ºC instead of 0ºC. Calculate the actual value of the measured temperature. I understand the question, I don’t understand why you don’t add the increase to all the other values when finding the “gradient” if the reference was found to be 0.204 higher
