ABSTRACT:
A device for providing data as a guide to health management which is capable of highly accurate measurements measures various characteristics of the body of a subject by electrical measurements of the subject while he or she is grasping handgrips with which the device is equipped. Once measurement has begun, the impedance variability measured by the device is calculated at every sampling period, and if the value of this variability is continuously less than a predetermined amount over a number of samplings, it is concluded that the electrodes which apply a fixed current and the electrodes which detect voltage are making good contact with the subject's hands.
