Separate Good Pair
Separate Good Pair
The RFL
Separate Good Pair
or 4-wire test allows you
to determine the distance to a short, ground, or
battery cross on a faulty cable conductor using two
separate good cable conductors.
Connect a strap from the faulted wire to both
conductors of the good pair.

The
connection diagram
shows you how to
connect the cables to the unit.

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 A1/A/B (T1/T/R) at the far end
for 4-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: Unlike 2-wire RFL, G/E on the FED is not grounded (on the FED side).
Note:
Results are more accurate but less forgiving than a 2-wire setup because
the 4-wire setup requires you to connect the faulted wire conductor to the
Ring (red) jack only.
