Claim 6:
7. A method for determining a distance to a short in a two-conductor wire, comprising:
injecting a selected pulse into a first end of the two-conductor wire, the selected pulse having a selected peak voltage and a selected pulse shape;
measuring a peak voltage of a combined pulse at the first end of the two-conductor wire resulting from injecting the selected pulse; and
determining a distance to the short in the two-conductor wire based at least in part on the measured peak voltage of the combined pulse;
wherein prior to injecting the selected pulse, the method further comprising:
injecting a test pulse into the first end of the two-conductor wire while no shorts are present in the two-conductor wire;
measuring a peak voltage of a returned test pulse at the first end of the two-conductor wire resulting from injecting the test pulse;
determining a distance to a second end of the two-conductor wire based at least in part on the measured peak voltage of the returned test pulse;
determining whether the determined distance to the second end of the two-conductor wire is the same as a known length of the two-conductor wire; and
performing a calibration operation in response to determining that the distance to the second end of the two-conductor wire is not the same as the known length of the two-conductor wire; and

wherein the processor is configured with processor-executable instructions to inject the selected pulse into the first end of the two-conductor wire by injecting the selected pulse into the first end of the two-conductor wire in response to determining that the distance to the second end of the two-conductor wire is the same as the known length of the two-conductor wire.
