  • RJ45 Bandari: For connecting Ethernet cables for wiremap testing.

5. Kuweka

5.1 Ufungaji wa Betri

The NF-810 requires 1 Lithium Metal battery (9V laminated battery) for operation. Ensure the battery is installed correctly in both the Emitter and Receiver units.

  1. Locate the battery compartment cover on the back of each unit.
  2. Fungua kifuniko kwa kutelezesha au kukifungua.
  3. Insert the 9V battery, observing the correct polarity (+/-) markings.
  4. Funga kifuniko cha sehemu ya betri kwa usalama.

6. Maagizo ya Uendeshaji

6.1 Cable Measurement (Wiremapping)

This function detects breaks, shorts, crossovers, and shielding issues in LAN (RJ45) and telephone (RJ11) cables.

  1. Unganisha ncha moja ya kebo kwenye mlango wa RJ45 au RJ11 kwenye kitengo cha Emitter.
  2. Connect the other end of the cable to the corresponding RJ45 port on the Receiver unit.
  3. Turn the Emitter's function dial to the 'CONT' position.
  4. Observe the wiremap indicators (LEDs 1-8 and G) on both the Emitter and Receiver.
  5. Muunganisho wa Kawaida: LEDs on both units will light up sequentially from 1 to 8, then G (for shielded cables).
  6. Fungua Mzunguko: If a specific LED does not light up, that wire is open.
  7. Mzunguko mfupi: If two or more LEDs light up simultaneously, a short circuit exists between those wires.
  8. Kuvuka: If the sequence of LEDs is incorrect (e.g., Emitter 1 lights up, but Receiver 2 lights up), a crossover is detected.

6.2 Wire Tracing (Scanning/Tone Function)

This function helps locate and identify specific cables within a bundle or wall.

  1. Connect one end of the target cable to the RJ45 or RJ11 port on the Emitter unit. For non-RJ cables, use the alligator clip cable to connect to the wire pair.
  2. Turn the Emitter's function dial to the 'SCAN' or 'TONE' position. The Emitter will generate an audible tone.
  3. Turn on the Receiver unit and adjust the sensitivity knob to a suitable level.
  4. Use the Receiver's probe to scan the cables or wires you suspect are the target.
  5. The Receiver will emit a louder sound and/or the yellow-green signal indicator will illuminate more brightly when it detects the tone from the target cable.

6.3 PoE Tester Function

The NF-810 can detect Power over Ethernet (PoE) presence, identify PoE switch types, and measure the number of PoE power supply cores.

  1. Connect the Ethernet cable from the PoE source (e.g., PoE switch) to the RJ45 port on the Receiver unit.
  2. The Receiver will automatically detect PoE presence.
  3. Observe the LEDs on the Receiver unit. They will indicate the PoE power supply cores (Mid-span or End-span) and potentially the voltage.
  4. Tahadhari: The device is designed to withstand voltages up to 60V. Do not test circuits exceeding this voltage kuzuia uharibifu.

6.4 Telephone Line Detection

This feature allows for detecting the polarity, on/off status, and standby status (idle, ringing, talk) of telephone lines.

  1. Connect the telephone line to the RJ11 port on the Emitter unit.
  2. Turn the Emitter's function dial to the 'TEL' position (if available, or use 'CONT' and interpret the LEDs).
  3. The LEDs will indicate the line status:
    • Bila kazi: Specific LEDs will light up, indicating a normal standby line.
    • Mlio: LEDs may flash or change pattern during an incoming call.
    • Ongea: LEDs will indicate the active talk state and polarity.

7. Matengenezo

Proper maintenance ensures the longevity and accuracy of your NF-810 tester.

  • Kusafisha: Futa kifaa kwa kitambaa laini na kavu. Usitumie visafishaji vya abrasive au vimumunyisho.
  • Hifadhi: Hifadhi kifaa mahali pa baridi, kavu, mbali na jua moja kwa moja na joto kali.
  • Utunzaji wa Betri: Ondoa betri ikiwa kifaa hakitatumika kwa muda mrefu ili kuzuia kuvuja.
  • Ulinzi wa Uchunguzi: Ensure the Receiver's probe is not bent or damaged during storage or transport.

8. Utatuzi wa shida

If you encounter issues with your NF-810, refer to the following common problems and solutions:

TatizoSababu inayowezekanaSuluhisho
Kifaa hakiwashi.Betri iliyokufa au iliyosakinishwa vibaya.Angalia polarity ya betri; badilisha na betri mpya ya 9V.
Inaccurate wiremap readings.Poor cable connection; damaged cable; incorrect mode.Ensure cables are fully inserted. Test with a known good cable. Verify Emitter is in 'CONT' mode.
No tone detected during scanning.Emitter not in 'SCAN' or 'TONE' mode; Receiver sensitivity too low; dead battery in Emitter.Set Emitter to 'SCAN' or 'TONE'. Increase Receiver sensitivity. Replace Emitter battery.
