Overview NF-308 is a practical cable test & inspection instrument with lots of new functions researched and developed by our company, which 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.
Main Functions and features ●One person enough to complete cable continuity check. ●Directly hunt 5E, 6E, telephone wire, coaxial cable, USB cable and other cables. ●Check wiring error in 5E, 6E, coaxial cable, such as open circuit, short circuit, jumper wire, reverse connection . ●Locate the wiring or connection error. ●Measure cable length and determine the distance of open circuit and short circuit. ●Dynamically calibrate cable length and make length measurement as accurate as 98%.
(5). Type of cable detected 5E, 6E, telephone wire, coaxial cable, USB cable and other metal wires. (6). Ambient temperature in work -10℃~+60℃ (7). Tester Port Tester RJ45 master port (M), tester LOOPBACK RJ45 port (L), RJ45 Scan( RJ45 cable tracing); Remote identifier RJ45 port (R) The extra BNC and RJ11 converters are used to measure and check the continuity of coaxial cable and telephone line. (8). Length Measurement of Twin Twisted Cable Scope: 1~350 M ( 3 ~1000 ft) Calibration accuracy: 3% (+/- 0.

Product operation methods Bott Screen: Carry out self-checking at the same time (The dotted line dynamically displays the course of self-checking from left to right): NetWork Cable Tester Wait 5 seconds or push any arbitrary key to display main menu. Main menu display: 1.wiremap 2 . p a i r &l e n g t h 3.coax/tel 4.setup There are four functions to be chosen on main menu. 1. WireMap --- Wiring diagram measurement to check end-to-end continuity of cables in M, L, R and locate errors. 2.
Test Result 1: Short circuit (SHORT) It displays as follows if there is any short circuit in cable or terminal: (e.g.12 short circuit in the sample) Short: 12 At the moment, push key to restart testing or push PAIR&L key to return main menu.Always eliminate “short”error firstly and then start further measurement.
Test Result 4: Wiring diagram (WIREMAP) display when there is an open circuit at the far-end of cable. Wire map:fail R:12x45x78 id1 Iiiiiiii M:12345678 " R:" line "3" and "6" pins location display "x", it indicates an open circuit in far-end plug "3" and "6" pins and the open circuit is located nearby the far-end plug.(The open point should be at the 10% cable length) Note: because the detected cable is made of paired cable cores, “open” error at the far-end always displays in pair as above.
Pair and length measurement (PAIR & LENGTH) function: After entering into “PAIR & LENGTH” function, it will display as follows to indicate the measurement is being undertaken: ----T e s t i n g ---12345678... Note:In view of different technical parameters in various brand cables, the user should calibrate the cable length before length measurement (Refer to the details herein).
Test Result 3: Abnormal pair and length (PAIR &LENGTH) display It will display the paired lines and its length first ly,then unpaired lines display, as shown below. Pair 1 2 1 0 0 . 0 m Pair 3 6 1 0 0 . 3 m Pair 4 5 1 0 0 . 2 m 78 The last line (78 ) indicates no pair is found in line 7and 8, at the moment,push the key, it will display the length of unpaired line number(as shown below) Pin Pin 7 100.0m 8 89.
Calibration and setup (SETUP) function: After entering into calibration and setup (SETUP) function, the tester shall display as follows: ----s e t u p ---Unit:meter Calibration Quit UNIT: It is used to set up length unit and shifts between meter (Meter) and feet (FT). CALIBRATION is calibration function.(Detailed as related chapters hereinafter) QUIT is used to return the main menu.
If there is short circuit in cable, It will display as follows. Short 12 Continue? No yes At the moment, push key (No) to exit calibration function. Push (Yes) to repeat the measurement. key Note: The calibration will recover the standard value of Class UTP5 cable at factory. Start up or shut down AF hunting function (1).
