K-Test Hookup: Close Far-End
The 965DSP will display the following screen if it
does not detect any hook-up errors during the “Open
Far-End” test.
The “Open Ratio” value displayed on the screen
is the ratio of R1/(R2+R1) times 100. This value
is used by some companies as part of the K-Test
measurement. It is not needed to actually calculate
the distance to the faults.
Note that the above screen indicates that the fault
resistances (R1 and R2) are OK!
If you are using a far-end switch, the 965DSP will
automatically send a command to close the far-
end. If you are not using a far-end switch, you or
somebody should manually short (or “strap”) the far-
end before you continue. Press [Enter] to continue
the K-Test.
