How i am going to confirm or make sure the accurate of thermocouple before i use it for measurement in experiment?
Is it ok if ...
I put it in ice in order to get 0 Celsius and put in boiling water to get 100 Celsius?
In the idea case, i should get 0 and 100 Celsius from thermometer..
but what i should do if i got slightly different ?
I don't know how to present about the error if i use it for real experiment...i need help on it...please..
