Title:

ELECTRONIC MEASURING DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/069930

Kind Code:

A1

Abstract:

When a detection error in any of a geomagnetic sensor, an acceleration sensor, and an angular velocity sensor exceeds a threshold value and a sensor flag is set to "1" (ST3, 5, 7), the present invention shifts to an integrated calibration process in ST10. In the integrated calibration process, a sensor in which a detection output error is occurring is calibrated using the detection outputs of the other two types of sensors.
