Tolerance of the thermocouple probes:
The tolerance of a type of thermocouple corresponds to the maximum acceptable deviation
from the e.m.f. of any thermocouple of that type, with reference junction at 0°C. The
tolerance is expressed in degrees Celsius, preceded by the sign.
The tolerances refer to the operating temperature expected for the thermocouple, in agreement
with the diameter of the thermoelements.
