RFL Single Pair (2 wire) Test
RFL Single Pair (2 wire) Test
Resistance fault locator (RFL) testing is a powerful means to locate shorts
between tip to ring, tip to ground, or ring to ground. The RFL-2 wire test,
also known as RFL single pair test, allows you to locate resistive faults
between tip to ring, tip or ring to ground, or the adjacent live pair.
Note:
Before performing RFL tests install a strap at the other end of the cable.
Test Setup
The
Test Setup
tab allows you to configure parameters for the RFL test.
Each parameter on the pane is
described below.
³
Sect.
denotes the section number
in the cable. Select to enable or
disable that section of the cable.
³
Cable Type
defines the gauge of
the cable in use. If wire gauge is
measured in AWG units, the
available choices are:
AUTO
,
19 AWG
,
22 AWG
,
24 AWG
, or
26 AWG.
For mm gauge wire, the
available choices are:
AUTO
,
0.32 mm
,
0.40 mm
,
0.50 mm
,
0.60 mm
,
0.65 mm
,
0.80 mm
,
0.90 mm
, or
1.20 mm
.
³
Ohm/mi
or
Ohm/km
is the resistance constant of the cable per unit
length.
³
Len.
is the length of the cable under test. Specify a maximum of four
characters.
³
Temp.
is the temperature of the cable under test. Specify a maximum
of three characters. Default is 60F or 20C.
³
L.Coil
specifies the presence or absence of load coil in the cable
section. Select
YES
or
NO
.
