 Specifications of the accuracy in the field of utilization:
Typical specifications = SPEC (1 + 0,05  t ° C)
Specification of the considered measurement. Values given p. 33 to 38.
 T: difference between ambient temperature and input terminal nearest to
the field of reference.

Example : temperature: 38° C
 t ° C = 38 - 28 = 10° C
SPEC (38° C) = (0.02 % + 8 D) (1 + 0,05  10)
