Reference Junction accuracy 0.2°C from 15°C to 35°C. Outside this
range (0-15 and 35-50) the maximum error is 0.3°C.
A
% of full scale +/- 1 digit.
B
Accuracy stated at 25°C, traceable to NIST.
C
% of full scale +/- 1 digit for 3-wire and 4-wire modes. The additional
uncertainty of the 2-wire mode is lead resistance and contact
resistance.
