nabend Eine Frage an alle die das Pollin Kompassmodul HDMM01 benutzen: im Datenblatt steht: ... However, the influence of a strong magnetic field (more than 5.5 gausses) along the magnetization axis could upset, or flip, the polarity of the film, thus changing the sensor characteristics. A strong restoring magnetic field must be applied momentarily to restore, or set, the sensor characteristics. The MEMSIC magnetic sensor has an on-chip magnetically coupled strap: a SET/RESET strap pulsed with a high current, to provide the restoring magnetic field. ... Wie oft muß ich den SET/RESET durchführen ? Laut Pollin Beipackzettel vor jedem Messvorgang. Ist das notwendig ? gruß marco
