5 seconds later, the following main interface is displayed:
There are nine functional options in the main menu interface
(1) Language— English or Chinese.
(2).Wire mapping --- Connection and disconnection test: to test connection
of M, S R end-end cable and perform positioning of the failure.
(3).Cable Length---Pairing and length measurement: verify cable length,
open circuit distance and pairing, crosstalk.
(4).Scan cable---to find target cable among lots of network cables,
telephone cables, USB cables, coaxial cables and other kinds of wires.
(5).Type--- Pair / Tel / USB / COAX / BNC Cable.
(6).Unit---Meter / Feet / Yards.
(7).Calibrate— Seven calibration coefficient can be stored in it.
User can calibrate network/ telephone/ USB/ Coax cables.
(8) Data loading---Select the calibration coefficients stored in system.
(9) Auto power off— set the time for power off.

Test result 1: Short circuit
If there is short circuit with the cable and terminal, it will show as below:
(Short circuit with 3 and 6)
Short mapping:
1 2 3 4 5 6 7 8
At this time, press any key to return to the main menu, and then press
"ENTER" key for re-test.
Please do not perform test again until short circuit problem solved.
Test result 2:
if the far end of the cable to be tested is not plugged in
remote adapter (R) or cable is not plugged into the local port (S),
the following interface is shown:
Cable open or
too Short
Test result 3:correct connection
:
the following interface is shown
Wire Map: Remote
1 2 3 4 5 6 7 8 G
M:
R:
1 2 3 4 5 6 7 8 G
"M"stands for Master unit. "R" stands for remote unit.
Test result 4: In case of open circuit existing on far end of the cable,
the following interface is shown:
Wire Map: Remote
1 2 3 X X 6 7 8
M:
R:
1 2 3 X X 6 7 8
In the figure, "X" shown in "4" and "5" pin position, indicates there is
open circuit in "4" and "5" pin of the remote pin.
