%ME: related to a full scale measurement range
1) The accuracy class implies that taken separately both the linearity deviation as well as the rotational signal uniformity is
either lower than or equal to the value of the accuracy class. The accuracy class is not to be identified with the classification
following DIN 51309 or EA‐10/14.
2) The factor of transmission declines linearly up to a maximum of 0.5% / 10K with rising temperature, due to the reduction of
the elasticity.
