Special use:
can test line sequence of the connecting cables In case of exchanger power-on, the main unit
Take network cable as an example: one end of the cable is connected with
“MAIN” interface of the main unit, and other end is connected with exchanger
interface. And direct connection test can be performed. If the exchanger
interface tested is reliably connected, the following interfaces shown (exchanger
interface is 8-core):
In case of open circuit with line 1 and 2 of the exchanger tested, the following
interface is shown (exchanger interface is 8-core):
1 2 3 4 5 6 7 8
Short mapping:
1 2 3 4 5 6 7 8
Short mapping:
b.Cable length test:(Test length only with the main
tester,don’t connect cable into remote unit.)
Firstly insert one end of the testing cable into “M” port in the main tester. When
entering ”Cable Length” testing function to check the length.At this time, the
following interface is shown:
Note: Due to different technical parameters with different branded cables,
users are recommended to use dynamic calibration function of the equipment
before measuring length (Refer to the related chapter for more details.).

Test result 1: Short circuit
If there is short circuit with the cable and terminal, the following interface is
shown (Short circuit with 3 and 6)
At this time, press any key to return to the main menu, and then press
“ENTER” key to other functions.
Please do not perform test again until short circuit problem solved.
Short mapping:
1 2 3 4 5 6 7 8
1 Open 105.0m
4 Open 105.0m
2 Open 105.0m
3 Open 105.0m
Test result 2: In case of normal pairing and length test,
the following interface is shown:
And then press “UP” or “DOWN” key, the following interface will further
be shown:
5 Open 105.0m
9 Open 105.0m
6 Open 105.0m
7 Open 105.0m
Thus , the cable is almost 105m . Only one end of cable connect with main
tester, the other end needs no connection, so it show "Open" in the picture
.
At this time,press “ENTER” to return to the main menu,and then press
“ENTER” key for re-test.
