360° EVALUATION

In order to distinguish between



and



+180° two additional measurements are needed: one with positive, the other

with negative coil current. In the next step the change in the signals due to the influence of the coil current must be

calculated. The sign of these coil-induced output voltage changes gives the 360°-information by case differentiation

(see figure 4). In principle, this 360° discrimination needs to be computed only once at start up. Nevertheless, it is

recommended to check the measurement periodically. Further details can be found in the corresponding application

note.
