Abstract
PURPOSE:To measure correct bioelectric potential, by applying a correction signal to a living body and detecting said correction signal to correct a bioelectric potential measured value. CONSTITUTION:A correction signal is applied between a human body and an earth point from a correction signal oscillator 1 and detected by the correction signal amplifier 2 of a differential amplifier for measuring the potential between the earth point and the human body and cardioelectric potential is measured by a cardioelectric amplifier 3. The correction signal amplifier 2 detects the correction signal applied to the human body to detect the contact state of an electrode 4. As the correction signal, an AC signal of a sine wave or rectangular wave is used. The cardioelectric amplifier 3 adjusts a mu-factor on the basis of the output voltage of the correction signal amplifier 2.
