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.

Use method of receiver
Remove the cover of battery pack, properly place in 9V battery, replace the
battery cover, hold the receiver and press and hold “Test” key with the thumb,
and then keep the detecting head close to the cable to find the target cable
among lots of cables. When the detecting head goes close to the target cable,
it beeps, and the same time the signal indicator “POWER” lights. Compare
loudness of beeps and brightness degree of the signal indicator. The cable
with loudest beeps and the highest brightness is just the target cable to find.
In a dark test environment, you may turn on lighting lamp on the receiver for
easy test as shown in the figure below:

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,
and therefore, network operation is interfered.
Connection diagram of crosstalk line pair
Crosstalk interface is shown as below:
Crosstalk line pair flashes
Note: In case of the non-twisted-pair cable like telephone cable,
due to over large crosstalk, it generally shown as crosstalk.
