Overview
NF-300 is capable
of avoiding current inteference . The equipment is composed
of three parts: main tester (NF-300), receiver (NF-300-S) and
remote identifier (NF-300-R).It has couples of circuit state testing
functions including length test, cable line finding, line-to-line,
crosstalk and breaking point, serving as a practical tool for low
voltage system installation and maintenance technicians
of communication circuits and comprehensive wiring circuits. It is
widely used in the fields like telephone system, computer networks
and other metal lead circuits.

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:

Both “4” and “5” pin are open curcuited. Or , either “4” or “5” pin is open.
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.

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):

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.).

1.Tracing cable (RJ45/RJ11 Cable) which is connected to
switch or router.
Insert the cable into port RJ11/ RJ45 (S), Press the testing key of receiver, “Power”
will be lighted, then hold the receiver close to the cables, when the probe gets close
to the targeted one, you can hear clear and loud “beep,beep, beep” .
(Note: telephone cable into RJ11, Lan cable into port RJ45(S) )
The usage of receiver
Install 9V battery, push the test key, get close to the cables with probe.you can
hear “beep”, the power led flashes. When the probe finds the targeted cable,the
voice will be loudest, and the led light will be brightest.
13
2.Tracing Coax cable
Insert the cable into port BNC, Press the testing key of receiver, “Power” will be
lighted, then hold the receiver close to the cables, when the probe gets close to the
targeted one, you can hear clear and loud “beep,beep, beep” .
(Note: turning down the voice slowly help trace cable easiler. )
3.Locate the short or breakge point (eg: metal line)
Connect the metal line with the cable clips, press the testing key of receiver, hold
the receiver close to the cables, “beep, beep,beep” will generate, but when the
probe targets the breakge point, “beep,beep,beep” stops, which indicates that
is where the breakage is.
Note: 1) the metal line is de-energized.
2) Turn up the voice, which helps locate breakge easily.
3) Two cables must be connected together, if only one cable, the black clip
has to be grounded.

d. Crosstalk test
As shown the figure below: it shows 3, 6 and 4, 5 with crosstalk. The line
pair with crosstalk will flash to indicate failure. In the line pair with crosstalk,
end-to-end connection is correct. However the connected lines are from
different line pairs. Line pair crosstalk will cause an over large crosstalk,
otherwise network speed will be slow.
Crosstalk interface is shown as below:
Note: In case of the non-twisted-pair cable like telephone cable,
due to over large crosstalk, it generally shown as crosstalk.
