Abstract
An electrode connector and connector condition sensor for a biopotential sensing apparatus wherein a plurality of electrodes are connected to individual output leads for individual electrode channels by a connector which does not abrade the surface of the electrode button contact and does not require that pressure be applied to the electrode during connection. Two spring biased conductive arms for the connector are spread apart by the cam surface of an actuator button to receive the button contact and are contoured to engage substantially the entire peripheral surface of the button contact when the actuator button is released. The biopotential sensing apparatus includes a processor which senses the loss of signal in any electrode channel during a test period and activates an indicator to provide a warning indication.
