(1) Tolerance is referred to as the maximum allowable deviation between measuring junction temperature and the temperature derived from the emf table．
(2) ASTM tolerance is ℃ or % value for the measured temperature, whichever is greater.
(3) |t| means measuring temperature indicated with the temperature (℃) having no connection with the positive or negative mark．
