Testers, Impedance, Electrode/Lead/Cable, Electroencephalographic

Definition : Impedance testers designed to measure the impedance between the biopotential surface electrodes typically used in electroencephalography and the skin; most testers are also capable of measuring the interference voltages that may be stored in the electrodes (offset voltage) and detecting faulty lead wires and/or cables. Electroencephalography electrical impedance testers are used to assess the ability of a large set (e.g., 20 or more) of surface electroencephalography electrodes to conduct the brain bioelectric signals from the skin to the electrodes, and/or through the leads and cables to the measuring unit.
