Abstract
A high-frequency signal generator generates a signal passing from the subcutaneous fat layer toward both the deep and shallow tissue areas. A second high-frequency signal generator generates a signal that passes primarily toward the deeper tissue. Frequency switch unit is used to select a signal of one of the frequencies. This signal is applied across whichever two of electrodes are selected by electrode switch unit 32a. The impedance across the two limbs in contact with those electrodes is measured using the electrical potential derived at whichever two of the electrodes have been selected. From the impedance values and personal data such as weight and height, the visceral fat mass, visceral-to-subcutaneous fat ratio and other useful indicators are calculated.
