6100-Cu Multifunction Copper Tester Operation Manual
FaultMapper does not find all faults but rather many
common faults, and can identify more than one at a
time. This test is useful in locating bridged taps, shorts,
grounds, and opens but only one bridged tap at a time.
(To look for more bridged taps, clear the first bridged
tap and run the test again). The TDR function key is
available for your reference, although FaultMapper is
not solely a TDR and performs some signal analysis.
FaultMapper can identify and/or locate the following:

Shorts

Grounds (strap required to determine distance)

Opens

Detect load coils

Bridged tap
The FaultMapper page displays the following
parameters:

Current Test displays the test being
measured.

Far End Strap allows you to select option Yes
or No for use of a strap.
A strap, while not required, enables
FaultMapper to calculate distance to a
ground/earth fault. The test will use some RFL
routines here, and you do not have to exit to
run RFL. (RFL is located on the Copper Main
menu.)

Cable Setup button opens a new page that
allows you to set the Cable Parameters for the
Current Test.

Result displays the cable faults in text and
graphical format.

Note: When running FaultMapper with a strap at the far
end of the pair, and there is a T-G/A-E fault, the
strap may also cause FaultMapper to display a
R-G/B-E short. In such cases, the resistance
shown is the resistance that would be measured
using a multimeter.

Estimated Length displays the cable length
when the cable is open.
Note: The cable length may include the Bridge Tap
length: remove the Bridge Tap for better
accuracy.

Fault Status displays the number of faults
detected (or No fault detected) after running
the test. The status Open detected is reported
in the following case:
o
No strap.
o
The pair is open.
o
No faults (other than the pair being
open).

Open and the distance to Open is displayed
and represented using X in the graph.

Test Status displays the current state of
measurement or an error message.

To select the parameter values:
1. Press the up/down arrow keys to highlight the
desired parameter.
2. Press the left/right arrow keys to view and
select the options.
OR
3. Press on a value to open a list box of
options.
4. Press to confirm the value.
Cable Setup
The Cable Setup page allows you to set the Cable
Type, Cable Length, and Cable Temperature for the
FaultMapper test. All other Cable Parameters are read
only and correspond to the current cable book entry as
selected in Setup/Cable Book/Cable Details page.
These cable parameters affect distance calculations of
Capacitance/Opens and Resistance measurements,
and the TDR cursor distance indication.
