Figure 1 shows a bridge tap detected at about 53,2 m. Only the first bridge tap detected is reported. The distance to a bridge tap is approximate because multiple reflections from the bridge tap interfere with length measurements.
Bridge taps more than 328 ft (100 m) from the tester
or taps less than 16 ft (5 m) long may not be detected.
