Copper and G.fast/VDSL2/ADSL2+ Multi-play Test Set

12 RFL
Resistance fault locator (RFL) testing is a powerful means to locate
resistive faults such as shorts, grounds, and battery crosses. Before
performing RFL tests, install the strap(s) at the other end of the cable. Use
of an oscillator or toner as a far end strap is not recommended. It will
induce errors. RFL consists of 3 tests: Single Pair, Separate Good Pair, and
K-Test.
Single Pair
The RFL
Single Pair
or 2-wire test allows you to locate
resistive faults between tip to ground, or ring to
ground. By default, the unit assumes that the fault
cable is connected to ring.
Connect the strap to the far end of the wires
connected to T/A and R/B.
The
connection diagram
shows you how to
connect the cables to the unit. The green lead is
used as reference.
When FED is
Enabled
on the
FED Setup
page, the
Confirmation
window pops up displaying how to
connect your cables at the beginning of the test.
The FED allows you to remotely place a
strap
(to
short together) the T-R/A-B pair at the far end for
2-wire RFL.
The
Confirmation
diagram uses graphic and
textual components.
Proceed
button closes the hookup diagram prompt and starts the
test.
Cancel
button closes the hookup diagram prompt only.
Note:
Results are less accurate than a separate good pair setup.
