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.
