Testers, Impedance, Electrode/Lead/Cable
Definition : Testers designed to measure the impedance between surface electrodes and the skin; most testers are also capable of detecting faulty lead wires and/or cables. These testers include an impedance-measuring instrument that typically works at low frequencies (e.g., 10 Hz, 30 Hz), measuring impedances from a few ohms to several hundred kilo-ohms; a display; and visual and/or audible alarms that indicate when the measured value is outside a predetermined range. Some testers are also capable of measuring interference voltages that may be stored in the electrodes (i.e., offset voltage). Electrode/lead/cable testers are used to assess the ability of electrodes to conduct bioelectrical signals (e.g., cardiac, encephalographic) from the skin to the electrodes and through the leads and cables to the measuring unit.
