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.
