Positive Identification System
See Figure 2.
The tester injects a tone onto the connected pair
concurrently with fault locating signals. This tone is
compatible with most tone probes. When you are using a
tone probe to identify a wire pair, the tone volume from
nearby wires may be indistinguishable from the tone from
the target pair. The SmartTone Positive Identification System
lets you positively identify the wire pair. The tone has 5
frequency and cadence options.

1. LLLL = the length to the fault.
2. An open may be a break in a wire or a separation between the
wires in the pair. If one wire in the pair separates from the other
wire for 1 ft or more, the tester indicates an open at the
separation.
