6100-Cu Multifunction Copper Tester Operation Manual
o
There is no strap connected.
o
There is a strap, but the cable is too long
and has a loop resistance >10 k Ohms.
o
There is a strap, but there is a high
resistance fault or open in the cable.
o
The connection (leads or strap) may be
faulty.
The resistance test may be used to
troubleshoot this problem.
Fault Status displays the status of the RFL
test.
Test Status displays the current state of
measurement or an error message.
14.2 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.
o
Proceed button closes the hookup
diagram prompt and starts the test.
o
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.
Current Test displays the test being
measured. When FED is Enabled, the FED
icon and numeric state are displayed beside
the Current Test.
Cable Setup button opens a new page that
allows you to set the cable parameters for the
Current Test. Press
Result displays the separate good pair RFL
test results. Based on the cable condition,
corresponding values are added into the
to open the page.
