Device for detecting electric potentials

摘要: A device for detecting electric potentials includes a plurality of measuring inputs ( 9 ) connecting to electrodes 11 ), which can be placed on the body patient 3 amplifiers (Op 1 , . Op N and potential output 27 an additional electrode 31 preset voltage applied. summing unit 17 sends signal, is indicator mean value signals sent by (Op1, OpN). current-measuring 29 current proportional flowing through output. An analyzing 35 connected receive 19 signal signal. The configured generate impedance from fed signals.
