Influences
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
DC measurement: 0,02 % + 8 D
t ° C = 38 - 28 = 10° C
SPEC (38° C) = (0.02 % + 8 D) (1 + 0,05
10)
= 0.03 % + 12 D
Electric field under 3 V/m: 1 per thousand at full scale. This influence does
not depend on the temperature.
