LCD Network Length Tester

Please read and learn safety instructions
before use or maintain the equipment
●Main testerr uses 6V DC for power supply;Receiver uses 9V
battery for power supply .
●Never put the equipment in the place with much dust, humidity
and high temperature (over 40℃).
●Please use battery according to the specification; otherwise, it
may result in damage to equipment.
●Please never dismount the equipment arbitrarily. The maintenance
and care shall be conducted by professional personnel.
●The tester will shut off automatically if it does not work for 30
minutes in succession.
●Please take out the battery in launcher and receiver if the
equipment is not used for a long time so as to prevent that the
battery liquid is leaked in future.
●Never use the equipment to detect power cord with electricity
(such as power supply circuit of 220V), other wise, it may result in
damage to equipment and personal injury.
●Never conduct related operation of communication line in
thunderstorm weather so as to prevent lightning stroke and
impact on personal safety.

Overview
LCD cable tester NF-8208 is an updated item after NF-8108. It is
composed of Main tester , Receiver and Remote identifier. Compared
to NF-8108, it can not only wiremap network cable, measure the length
of network cable, but it can also trace cables with its receiver, which
makes it a more popular tool in network and telecommunication field.

"R:" line "3" and "6" pins location display "x", it indicates an open circuit in
far-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: Because network cable is made of pair cores, if there is open circuit,
it will show faults in pairs, just as above "3" &" 6". it means either "3" pin or
"6" pin exsits an open circuit, or both "3" and "6" exsit an open circuit.
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

Note:In view of different technical parameters in various brand cables, the
user should apply the tester dynamic calibration function before length
measurement (Refer to the details herein).

"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
function (PAIR & LENGTH) of the tester could used as detailed hereinafter.

Test Result 3: Abnormal pair and length (PAIR &LENGTH) display
It will display the paired lines first if there is unpaired lines in the pair and
length (PAIR & LENGTH) measurement:

P a i r 3 6 1 0 0 . 3 m
P a i r 4 5 1 0 0 . 2 m
In which, the last line (78 ) indicates there is no pair in lines 7and 8, at
the moment, it will display the length of unpaired line number(as shown below):
It will display "X" to indicate an open circuit if the length is less than 90%of
other line pair length and the open circuit is located at around 89.3M from
the tester. (The open circuit line number could be rechecked by
WIREMAP function.)
P i n 7 1 0 0 . 0 m
P i n 8 8 9 . 3 m x
Note: NF-8208 can not check the wiremap of coax cable and telephone
cable directly, it needs RJ11 cable adaptor and BNC cable adaptor.
(The tester is incapable to know the exact location of short circuit.)
At the moment, push key to restart test or push key to return the
main menu.
Always eliminate short circuit and then start further measurement.
Test Result 2: Normal pair and length (PAIR &LENGTH) display

At the moment, push key (No) to exit calibration function. Push key
(Yes) to repeat the measurement.
Note:If the tester is restarted after it shuts off, the tester will recoverthe
standard calibration factor of Class UTP5 cable as setupbefore shipment.
At the moment, push key (No) to exit calibration function. Push key
(Yes) to repeat the measurement.
Start up or shut down AF hunting function
(1). Press PUSH key, the hunting indicator light (SCAN) flashes, which
indicates that audio frequency transmission of main tester is normal,
insert wire to be hunted into RJ45 port hold the receiver to trace the
targeted cable (the usage of receiver is shown in the following).
Usage of the receiver
Install 9V battery in the receiver, press the "PUSH" button to get close to cables
with probe. the transmitter will "beep, beep, beep" , when the probe is close to a
cable which makes the tone is loudest, it means the cable is the targeted one.
At the moment, hold and key (-/+) to display the length to be adjusted to
actual given length and then push key to reserve calibration factor and
exit calibration function.
It will display as follows if the cable length being measured is too short
(<10M) to remind the user to change a longer cable for calibration:
