Failure diagnostic device for acceleration sensor, electronic device equipped with failure diagnostic device, failure diagnostic system, and failure diagnostic method

摘要

A failure diagnostic device for diagnosing whether a failure has occurred in an acceleration sensor to be loaded in an electronic device such as a living body information measurement device of acquiring data concerning e.g. living body information includes: an acceleration calculator for calculating an acceleration applied to the electronic device based on an output from the acceleration sensor; and a first judger for judging whether the electronic device is in a stationary state based on a judgment as to whether an output value from the acceleration calculator lies within a predetermined range for a predetermined duration.
