Thermocouple, temperature controller, compensation wire, index number must strictly match.
Such as K type thermocouple must match K type thermostat and compensating conductor.
Otherwise the error of the measured is very large.
Check the index number on temperature controller and thermocouple inside the lid has a mark.
