is composed of tester (NF-308), receiver (NF-308-S) and remote
identifier. It owns three great functions of wire hunting,wire sorting
and circuit status testing quickly and accurately. 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 and other fields.

Start up or shut down and hunting function
(1). Press PUSH key,the hunting indicator light (SCAN) flashes,which indicates
that audio frequency transmission of main tester is normal , insert the cable to
be tested into RJ45 SCAN Port . then hold the receiver to trace cable needed
(the usage of receiver is shown in the following). RJ11/BNC/ USB cable is
located when inserted into its corresponding port.
(2).The user can turn volume switch to control the volume.
(3).The floodlight function helps the users operate in dark environment.
(4).Earphone helps avoid external interference in noisy environment.
(5).The test can not measure cable length and wire faults when it is
operated to trace cable.
Usage of the receiver
Install 9V battery ,press “PUSH” key, then approach the cable with probe
and find targeted one among lots of cables. When the probe is near target
wire, the “beep, beep and beep” sound will come out and the signal indicator
light “POWER” will be on. When loudest “beep” and brightest indicator
means that is the required cable.
If there is short circuit in cable, It will display as follows.

Polarity test
Firstly, insert into RJ11/SCAN port with the standard alligator clips.
Secondly, choose “polar Test” from the main menu when you have clamped the
battery polarity with the clips.
Thirdly, you can see the result shown on the screen: Voltage of the battery, Red
& Black tells you the polarity. (“+”means anode , “-”means cathode).
ATTENTION: whenever you connect anode or cathode for the red & black clips,
it's doesn't matter for the result.
