NOYAFA NF-8200 - Manual (Page 6)

07
Note: Because network cable is made of pair cores, if there is open circuit,
it will show faults in pairs, just as above "4" &" 5". it means either "4" pin
or "5" pin exsits an open circuit, or both "4" and "5" exsit an open circuit.
Test result 5: In case of open circuit existing at the near end of
the cable
, the following interface
is shown:
when testing only with main tester
In the figure, “X” shown in “3” and “6” pin position in “M” line, indicates there is
open circuit in “3” and “6” pin of the near pin.
Test result 6: In case of open circuit existing at the middle part
of the cable
, the following
interface is shown:
when testing only with main tester
In the figure, “X” shown in “3” pin position in “M” and “S” line, indicates there is
open circuit in “3” pin of the middle part of the cable. Perform"PAIR&LENGTH"
to locate the exact fault point. Refer to the related chapter below.

Test result 4: In case of open circuit existing on far end of the cable,
the following interface is shown:
In the figure, “X” shown in “4” and “5” pin position in “S” line, indicates there is
open circuit in “4” and “5” pin of the remote pin.

Test result 7: In case of open circuit existing in the cable when
testing with main tester and remote unit together, the following
interface is shown:
In the figure, “X” shown in “4” & “5” pin in “M” & “R” line, It has two possible results.
Both “4” and “5” pin are open curcuited. Or , either “4” or “5” pin is open.

Test result 8: 6-core telephone cable line sequence test
At this time, press any key to return to the main menu, and then press
“ENTER” key for re-test.
Before checking wiremap of telephone cable, users need to choose "RJ11"
and then check its wiremap. If the testing cable is in good connection, it will
displays as follows:
Wire Map: Remote
1 2 3 4 5 6 M:
R: 1 2 3 4 5 6
Note: When checking wiremap with main tester and remote unit together,
the cable is tested in pair. Thus, if there is one pin is open , it will show in pair
as above.
To test which pin is open, users can check wiremap only with main tester like
Example 4,Example 5 and Example 6 do.
