Abstract: A method for determining the health of an individual sensor, within a plurality of individual sensors that are wired together to form a receiver point. The method includes receiving positions of the plurality of individual sensors along the cable, recording the trace associated with measured plural signals from the plurality of individual sensors, as an external device moves along the cable, past the individual sensor, and determining a health status of the individual sensor of the plurality of individual sensors by identifying a signature SI of the individual sensor in the recorded trace. The external device emits a noise when moving along the cable, and the noise is detectable only by the individual sensor of the receiver point when the external device is located over the individual sensor.
