(5) Temperature conversion characteristic 
Thermocouple input module converts the thermocouple input with non-linear characteristics into 
A/D and outputs the temperature conversion that is linearly treated.   
Temperature conversion to thermocouple input has non-linear characteristics.

Non-linear characteristics: regarding the relation of temperature(℃) and electromotive force(㎶) of a 
thermocouple sensor, electromotive force is different by sections even though temperature changes 
by a certain amount, which is called ‘non-linear characteristics.’ As seen in  the above graph, it is 
shown that the relation of temperature and electromotive force is a curve by temperature sections. 
The module processes the non-linear characteristics table as linear.
