RFL Test
210 FTB-635
RFL-K-Test
The page allows you to set the following parameters:
Select Cable button opens a new page that allows you to set the cable
parameters for the current test. Refer Setting Cable Parameters on
page 212 for more information.
Save Test button opens a new page that allows you to save a snapshot
of test results into a result file. Refer Save Test on page 74 for more
information.
Based on the cable condition, corresponding values are added into the
diagram at their specific positions. Test result measurement units are
dependent on Standard in Setup/Application Settings. The
RFL-K-Test diagram can display some of the following elements:
R/A-T/B-G/E wire connectors.
Distance/resistance to strap (DTS/RTS): distance/resistance from
the FTB-1 to the strap (far end).
Distance/resistance from fault to strap (DFTS/RFTS).
Distance/resistance to fault (DTF/RTF): distance/resistance from
the FTB-1 to the fault.
Faults are displayed as follows:
Defective Cable (DC).
Resistance at fault (Rf1, Rf2): resistance from the fault to the
resistance wire.
Voltage at fault (Vf1, Vf2).
Note: There need not be 2 faults (Rf1, Rf2). If there is only one fault, the K-Test
reduces to the RFL-2-Wire case.
