The tester 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 mainten
-ance and care shall be conducted by professional personnel.
The tester will shut off automatically if it does not work for
15 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
NF-868 type multipurpose communication cable tester & tracker
is a cable tester and tracker with more functions newly developed by
our company. The equipment is composed of three parts: main tester
(NF-868-M), receiver (NF-868-S) and remote identifier (NF-868-R).
The new equipment enjoys a smooth design, good feel and humanity
design. It has couples of circuit state testing functions including
length test, cable line finding, line-to-line, crosstalk and breaking
point and features fast and accurate, and thus serves 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.

Product interface and key introduction
Main unit port instructions
(1). Two RJ 45 interfaces on the main unit:
one of them is “MAIN” interface (M interface in short),
and the other is “SCAN” interface (S interface in
short); there are also RJ11 interface, USB interface
and BNC interface;
(2). M interface is used for measuring length and
others, but not for cable Line finding; S interface is
used for Line finding test and “local” connection test;
(3). RJ11 interface, USB interface and BNC interface
on the main unit are used for
line-to-line, length and Line
finding test.

(1).Connection test --- Connection and disconnection test: to test connection
of M, S R end-end cable and perform positioning of the failure;
(2).Length test---Pairing and length measurement: to verify cable length, open
circuit distance and pairing, crosstalk;
(3).Line finding---to find target cable among lots of network cables, telephone
cables, USB cables, coaxial cables and other kinds of wires;
(4).Parameter setup---Calibration and setup (Refer to the related chapters
below)Press “UP” and “DOWN” key to move the cursor “ ”upwards
and downwards to the corresponding items, and then press “ENTER”
key to enter corresponding test function.
Test method (Totally four methods)
(1). M-S method---When testing network
cable sequence and length with the main
unit, one end is connected with the “MAIN”
interface of the main unit, and the connection
of the other end with “SCAN” interface of the
main unit is as shown in Figure 1:

USB cable, coaxial cable with the main
unit and remote identifier is as shown
in Figure 2:
S method---Using method of Line
finding network cable with the main unit
is as shown in Figure 3:
Open circuit method---When
measuring test, one end is connected
with the main unit, and the using method
that the other end is neither connected
with the remote identifier nor “local” is
as shown in Figure 4:

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 for re-test.
Please do not perform test again until short circuit problem solved.
Test result 2:Fail to find remote adapter (R) or local port (S) cable: if
the far end of the cable to be tested is not plugged in a remote adapter (R)
or when to perform local test, cable is not plugged into the local port (S),
the following interface is shown:
At this time, press any key to return to the main menu, and then press “ENTER”
key for re-test.
Test result 3:In case of correct connection, the testing device will
automatically detect the remote adapter (R) or local port (S) cable. If it detects
that the far end of the cable to be tested is with a remote adapter (R) or local
port cable, the following interface is shown:
At this time, press any key to return to the main menu, and then press “ENTER”
key for re-test.
Wherein: “R” line indicates pin position of the remote adapter RJ45 port;
Wherein: “S” line indicates pin position of local RJ45 port;
Wherein: “M” line indicates pin position of local main end RJ45 port.
