  "textContent": "To provide an electronic equipment having a built-in electronic compass that detects terrestrial magnetism using a magnetic sensor, which is drivable with efficiency, and displays a compass direction (north). In this electronic wrist watch, a comparison means compares a detection value obtained by the first detection with a detection value obtained by the second detection, for instance. The reproducibility judgment means judges whether there exists reproducibility using a result of the comparison. In the case where there exists reproducibility, a pulse width setting means sets a short pulse width for a magnetic field. This makes it possible for a reset means to reset a magnetic sensor using electromagnetic energy that is required to reset the magnetic sensor.",
