RFL Single Pair

Use the RFL Single Pair hookup when only one wire in a pair is faulted and a reference pair is not available. Use the Separate Pair hookup for all other cases; it is the preferred method.

You must first use the Resistance function to identify a faulted conductor in a pair and to verify that the other conductor is not faulted.

Once you identify the wires, connect the Strap at a ‘far-end’ access point to the same faulted conductor and good conductor.

Press the RFL key and select “Single pair”. Connect the Red test lead to the faulted conductor in the pair. Connect the Green test lead to the unfaulted conductor in the same pair.

Connect the Black Lead to the reference. (The reference is the return path for the fault and could be the shield or another wire in the cable.)

Press the [Enter] key after you have made the above connections.

If there is a problem with the connection, you will see the “Hookup Error” screen on the next page. If the connections are OK, the 965DSP-B will go directly to the RFL results screen.
