Single Pair
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
to open the page.
Result displays single pair RFL test results. Based on the cable
condition, corresponding values are added into the diagram at their
specific positions. Test result units are dependent on Standard in
Setup/Application Settings.
Distance to strap (DTS).
Resistance to strap (RTS).
Distance from fault to strap (DFTS).
Resistance from fault to strap (RFTS).
Resistance to fault (RTF).
Distance to fault (DTF).
Faulted cable (FC).
Resistance at fault (Rf) is resistance from the fault to the resistance
wire.
Voltage at fault (Vf).
If the test reports that it cannot detect the strap when the measured
loop resistance is >10 k Ohm, this may mean:
There is no strap connected.
There is a strap, but the cable is too long and has a loop resistance
>10 k Ohm.
There is a strap, but there is a high resistance fault or open in the
cable.
The connection (leads or strap) may be faulty.
The resistance test may be used to troubleshoot this problem.
