may result in damage to equipment .
●Plea se never dismount the equip ment arbitrarily. The maintenance
and ca re shall be conducted by prof essional personnel.
● The tester will shut off automatically if it does not work for 30
minu tes in succession.
●Plea se take out th e battery in laun cher and receiver if the
equi pment is not used for a long time s o as to prevent that the
battery liquid is leaked in futur e.
●Neve r use the equipment to detect power cord with electricit y
(such as power supply circuit of 22 0V), other wise, it may result in
dama ge to equipment and persona l injury.
●Neve r conduct related operati on of communication line in

with fluent appearance,excellent hand feel and considerate human-centered
design.It owns three great functions of hunting,wire sorting and circuit status
testing and the features of quickness and accuracy,thus,it becomes available
tool for technicians in installation and maintenance of weak current system,
such as, communication line, comprehensive wiring circuit, etc. It is widely
applicable to telephone system, computer network, other metal wire circuit

Product operation methods
Start and display:
Carry out self-checking at the same time (The dotted line dynamically displays
the course of self-checking from left to right):
5 seconds or push any arbitrary key to display main menu.
Main menu display:
PAIR&L
Wiring diagram (WIREMAP) test function:
After entering the wiring diagram (WIREMAP) test function, the tester shall
carry out wiring diagram (WIREMAP) test and displays as follows while
checking is being undertaken:
----T e s t i n g ----

There are four functions to be chosen on main menu.
1. WireMap --- Wiring diagram measurement to check end-to-end con-tinuity
of cables M, L, R and locate error.
2. Pair & Length ---Pair and measure length to verify cable length,open circuit
distance, pairing and cross-talk interference.
3. Coax/Tel --- Coaxial cable and telephone line measurement to check
continuity and indicate open circuit and short circuit.
4. SETUP---Calibrate and set up the tester (Refer to description hereinafter).
With main menu display, push key to move cursor indicator up
and down to desired item and then push key to enterrelated test
function accordingly.

Test Result 1: Short circuit (SHORT)
It displays as follows if there is any short circuit in cable or terminal: (e.g.12
short circuit in the sample)
Short:
1 2
At the moment, push key to restart testing or push key to return main
menu.Always correct short circuit error first and then start further measurement.
Test Result 2: Neither far-end matcher (ID) is foundnor cable inserts
local port (L).The tester will automatically detect far-end matcher (ID) or local
port (L) cable and it will display as follows if the far-end of cable to be checked
does not insert into the far-end matcher (ID) or if the cable does not into the
local(L)in local test:
N o a d a p t e r :
At the moment, push key to restart testing or push key toreturn
main menu.
Test Result 3: Normal wiring diagram (WIREMAP) display
The tester will automatically detect far-end matcher (ID) or local port (L)cable
and it will display wiring diagram (WIREMAP) as follows if it is found the far-
end matcher (ID) or the local port (L) on the far-end of cable to be checked:

"R:" line shows RJ45 jack pin number of far-end port and "ID1"is the remote
identifier number.
"|" line shows the connecting line between far-end port and master port.
"M:" line shows the RJ45 jack pin number of master port.
At the moment, push key to restart testing or push key to return

Test Result 4: Wiring diagram (WIREMAP) display
when there is an open circuit at the far-end of cable.
W i r e m a p : f a i l
R: 12 x45 x78 id1
Iiiiiiii
M: 12345678
"R:" line "3" and "6" pins location display "x", it indicates an open circuit infar-
end plug "3" and "6" pins and the open circuit is located nearby the far-end
plug.(The open circuit should be located within 10% cable length if it is
measured from the far-end plug)
Note: If you use far-end matcher (ID) to measure wiring diagram(WIREMAP),
because the test is made via the paired two cable cores,the open circuit at the
far-end always displays in pair as shown above where there is one open circuit
or all are open circuits in the far-end"3"and "6"pins. For identification, it is
simple to move the tester to the far-end to have the measurement.
Test Result 5: Wiring diagram (WIREMAP) display when there is an open
circuit at the near-end of cable. It will display wiring diagram (WIREMAP) as
follows if there is an open circuit at the near-end plug of the cable:
W i r e m a p : f a i l
R : 1 2 3 4 5 6 7 8 i d 1

M : 1 2 x 4 5 6 7 8
"M:" line "3" pin location displays "x", it indicates an open circuit at near-end
plug "3" pin and the open circuit is located nearby the near-end plug.(The open
circuit should be located within 10% cable length if it is measured from the
near-end plug)
Test Result 6: Wiring diagram (WIREMAP) display when there is an open
circuit in the middle of the cable.It will display wiring diagram (WIREMAP) as
follows if there is an opencircuit in the middle of the cable:
W i r e m a p : f a i l
R : 1 2 3 4 5 6 7 8 i d 1
Iixiiiii
M : 1 2 3 4 5 6 7 8
"|" line "3" pin location displays "x", it indicates an open circuit in the middle
of "3" pin cable. (The open circuit should be located within 10%-90%cable
length if it is measured from the near-end plug.) For further locating open
circuit, the pair and length function (PAIR & LENGTH) of the tester could used
as detailed hereinafter.
