1. Introduzzjoni
The Tenmars TM-901N is a professional LAN cable tester designed for efficient and accurate diagnosis of network cable issues. It is capable of identifying various wiring faults such as discontinuity, short-circuits, incorrect connections, and split pairs in both Shielded Twisted Pair (STP) and Unshielded Twisted Pair (UTP) cables. This device can measure cable lengths up to 265 meters, making it an essential tool for network installers and technicians.
2. Informazzjoni dwar is-Sigurtà
Jekk jogħġbok aqra u ifhem l-istruzzjonijiet kollha tas-sigurtà qabel ma tħaddem l-apparat. Jekk ma ssegwix dawn l-istruzzjonijiet, tista' ssir korriment jew ħsara lill-apparat.
- Do not attempt to test live circuits or cables connected to active network equipment.
- Ensure the battery is correctly installed before use.
- Tesponix l-apparat għal umdità jew temperaturi estremi.
- Tiftaħx l-apparat casing, għax dan jista' jannulla l-garanzija u jesponik għal perikli elettriċi.
- Armi l-batteriji skont ir-regolamenti lokali.

The main unit features an LCD display for showing test results and cable status. It includes several control buttons:
- Buttuna TEST: Initiates a cable test.
- L/W Button: Toggles between Length measurement and Wiremap display modes.
- SET/UNIT Button: Used to enter settings mode and change measurement units (e.g., meters, feet).
- Buttuni tal-Vleġġa (Xellug/Lemin): Used for navigation in settings or for reviewriżultati tat-test.
4.2 Remote ID Locator

The rear panel of the main unit includes the battery compartment and a printed wiring diagram for reference, showing standard T568A/B pin assignments for RJ45 connectors.
5. Setup
5.1 Installazzjoni tal-batterija
- Locate the battery compartment cover on the rear of the main unit.
- Slide the cover open or remove it as indicated.
- Daħħal batterija ġdida ta' 9V, waqt li tiżgura l-polarità korretta (+/-).
- Ibdel l-għatu tal-kompartiment tal-batterija b'mod sikur.

5.2 Kejbils tal-Konnessjoni għall-Ittestjar
Before connecting any cables, ensure they are disconnected from all active network devices.
- For patch cables (uninstalled cables): Connect one end of the cable to the RJ45 port on the main unit and the other end to the RJ45 port on the remote ID locator.
- For installed cables: Connect the main unit to one end of the installed cable (e.g., a wall jack) and the remote ID locator to the other end of the cable (e.g., in a patch panel).
6. Istruzzjonijiet Operattivi
6.1 Tixgħel/Jitfi
The device typically powers on automatically when a cable is connected and the TEST button is pressed, or by pressing the TEST button. It usually powers off automatically after a period of inactivity to conserve battery.
6.2 Twettiq ta' Test tal-Kejbil
- Ensure the cable is properly connected to the main unit and the remote ID locator.
- Agħfas il- TEST buttuna.
- The tester will automatically scan the cable and display the results on the LCD.
6.3 Interpreting Test Results (Wiremap)
The LCD will display the wiremap, indicating the connection status of each wire pair. Common indications include:
- Għaddi: All wires are correctly connected (1-1, 2-2, etc. for straight-through, or appropriate cross-over mapping).
- Open/Discontinuity: A break in one or more wires. The display will show which wire(s) are open.
- Short-Circuit: Two or more wires are touching. The display will indicate the shorted wires.
- Incorrect Connection/Miswire: Wires are connected to the wrong pins at one or both ends. The display will show the incorrect mapping (e.g., 1-3, 2-6).
- Pari maqsuma: A more complex fault where two pairs are swapped, but the wiremap appears correct. The tester is designed to detect this.
6.4 Measuring Cable Length
- After performing a test, press the L/W button to switch to Length measurement mode.
- The display will show the estimated length of the cable.
- To change the unit of measurement (meters, feet), press the SET/UNIT button while in Length mode and use the arrow buttons to select the desired unit. Press SET/UNIT mill-ġdid biex tikkonferma.
7. Manutenzjoni
7.1 Tindif
Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the device.
7.2 Sostituzzjoni tal-batterija
When the battery low indicator appears on the display, replace the 9V battery as described in Section 5.1. Remove the battery if the device will not be used for an extended period to prevent leakage.
7.3 Ħażna
Aħżen l-apparat f'post frisk u niexef, 'il bogħod mix-xemx diretta u minn temperaturi estremi. Żommu fl-imballaġġ oriġinali tiegħu jew f'kaxxa protettiva meta ma jkunx qed jintuża.
8 Issolvi l-problemi
| Problema | Kawża Possibbli | Soluzzjoni |
|---|---|---|
| L-apparat ma jixgħelx. | Batterija baxxa jew mejta; batterija installata ħażin. | Replace the 9V battery; check battery polarity. |
