K-Test
 Result displays K-Test results.
 Open Ratio is a comparison between Fault 1 and Fault 2. The
larger the fault size difference, the lower the open ratio number.
 Closed Ratio is a comparison between sections. The larger the
Closed Ratio value, the closer the fault is to the strap end.
 Lx/L displays a length ratio where Lx = Length to fault and
L =total Length.
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. The 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 MaxTester to the strap (far end).
 Distance/resistance from fault to strap (DFTS/RFTS).
 Distance/resistance to fault (DTF/RTF): distance/resistance from
the MaxTester 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).
