1) The accuracy class implies that taken separately both the linearity deviation as well as the rotational signal uniformity
are 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) Zero point can be set to 5 V by pressing the Tera-button.
3) The factor of transmission declines linearly up to a maximum of 0,5 % / 10K with rising temperature due to the reduction
of the elasticity.
