Please read and learn safety instructions before use or maintain the equipment CONTENTS Overview......................................... .... .....01 ● Keep the testers in right place to avoid hurt with the sharp probe. ● Never put the equipment in the place with much dust, humidity Main functions .................................. .... ...02 Technical Parameters...................... .... .....02 and high temperature (over 40℃).
Overview Main functions NF-868 Series are newly developed by our company which are capable of avoiding current inteference . The equipment is composed of three parts: main tester (NF-868-M), receiver (NF-868-S) and remote identifier (NF-868-R).
(5).Detecting cable types STP/UTP 5E, 6E network cable, telephone cable, coaxial cable, USB cable and common metal wires connected with alligator clip. Product interface and key introduction (M) (S) MAIN SCAN BNC (6).Operating environment temperature/humidity -10℃ ~ +60℃ /20% ~ 70%; (7).Testing device interface Main unit: RJ45 (M), RJ45 (S), loop interface, RJ11, BNC connector, USB B-type female interface; Remote identifier: RJ45, RJ11, BNC connector, USB A-type female interface.
Product operation method Test result 1: Short circuit Bootscreen If there is short circuit with the cable and terminal, it will show as below: (Short circuit with 3 and 6) Synchronous self test ( ------self test dynamically displayed in the line from left to right) Short mapping: welcome to choose noyafa NF-868 5 seconds later, the following main interface is displayed: Lang:English Wire mapping Cable Length S can Cable 1 2 3 4 5 6 7 8 At this time, press any key to return to the main menu, and then
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.
Remote unit with tone when checking wiremap Test result 1: Short circuit When use remote unit to check wiremap, users can distingush the test result firstly via tones. When the cable is normal, the remote unit will generate “ beep ” long and slowly. When the cable is abnormal, the the remote unit will generate “ beep ” short and quickly.
Test result 4: RJ11(TEL) cable length test c. Cable tracing test: Insert one end of the RJ11 cable to be tested into “RJ11” port of the main tester, the other end needs no connection.
The usage of receiver 2.Tracing Coax cable 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. 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” .
d. Crosstalk test Choose the Language, Chinese or English 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. 3 3 6 6 then you can get the screen as you desired.
3).Type: USB cable When testing USB cable, users need to firstly choose”USB(4)” in”Type” after this, users can test cable length and check its wiremap. When starting dynamic calibration, insert the same type of cables at a specified length into “M” port. It is unnecessary to insert into remote unit. Calibration No ? Yes 4). Type: BNC coaxial cable When testing BNC cable, users need to firstly choose”BNC(2)” in”Type” after this, users can test cable length and check its wiremap.
