Overview LCD cable tester NF-8208 is an updated item after NF-8108. It is composed of Main tester , Receiver and Remote identifier. Compared to NF-8108, it can not only wiremap network cable, measure the length of network cable, but it can also trace cables with its receiver, which makes it a more popular tool in network and telecommunication field. POWER NF-8208-S NF-8208 1.wiremap 2 . p a i r &l e n g t h 3.coax/tel 4.
Main Functions and features ●One person enough to complete cable continuity check. ●The funtion of probing the audio and tracing the cable. ●Check wiring error in 5E, 6E, such as open circuit, short circuit, jumper wire, reverse connection. ●Measure the length of network cable, and locate the open and short point. ●Simple and easy use. Big screen to display test result clear. ●Portable unit with long battery life (wait-case 50 hours). ●Automatically time-delay shut off.
(5). Type of cable detected 5E, 6E (6). Ambient temperature in work -10℃~+60℃ (7). Tester Port Tester RJ45 master port (M), tester LOOPBACK RJ45 port (L), hunting RJ45 port(SCAN); 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% (+/- 0.5M or +/- 1.5 ft) (calibrating cable > 10 M) Shipment accuracy: 5% (+/- 0.

Product operation methods Start and display: 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 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 con-tinuity of cables M, L, R and locate error. 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 correct short circuit error first 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.
Test Result 6: Open circuit in the middle of cable It will display wiring diagram (WIREMAP) as follows if there is an open circuit in the middle of the cable: Wire map:fail R :1 2 3 4 5 6 7 8 i d 1 Iixiiiii M :1 2 3 4 5 6 7 8 "|” line "3" pin location displays "x", it indicates an open circuit in the middle of "3" pin cable. (The open circuit should be located within 10%-90%cable length if it is measured from the near-end plug.
(The tester is incapable to know the exact location of short circuit.) At the moment, push key to restart test or push PAIR&L key to return the main menu. Always eliminate short circuit and then start further measurement. Test Result 2: Normal pair and length (PAIR &LENGTH) display It will display as follows if pair and length(PAIR & LENGTH) measurement is in normal condition: At the moment, push Pair Pair Pair Pair 12 100.0m 36 100.3m 45 100.2m 78 99.
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 Dynamic calibration (CALIBRATION) function: (Another way to quickly enter into dynamic calibration: hold PAIR&L key while start the tester) For an accurate measurement of cable length,the calibration operation should be done as follows.
At the moment, hold and key (-/+) to display the length to be adjusted to actual given length and then push PAIR&L key to reserve calibration factor and exit calibration function. It will display as follows if the cable length being measured is too short (<10M) to remind the user to change a longer cable for calibration: Cable to short! coht innt. cai No yes At the moment, push key (No) to exit calibration function. Push key (Yes) to repeat the measurement.
