عملیاتي لارښوونې
Basic Cable Testing (Wiremap)
- Connect one end of the cable to be tested to the "PORT" input on the main TDR unit.
- Connect the other end of the cable to the corresponding port on the Wire Tracker Receiver.
- Select the "TEST" mode on the main unit.
- The display will show the wiremap, indicating continuity, open circuits, short circuits, split pairs, or miswires.
Cable Length Measurement (TDR)
- Ensure the cable is disconnected from any network devices.
- Connect one end of the cable to the "PORT" input on the main TDR unit. Leave the other end open.
- Select the "SCAN" mode or TDR function.
- The display will show the cable length in feet or meters. Use the "ft/m" button to toggle units.
- The TDR function can also locate the distance to faults like open or short circuits.
د PoE کشف
- Connect the cable from the PoE source to the "POE" input on the main TDR unit.
- Select the "POE" mode.
- The display will indicate if PoE is present and identify the PoE standard (802.3AF, 802.3AT, 802.3BT).
Wire Tracking (with Receiver)
- Connect the cable to be traced to the main TDR unit.
- Activate the "SCAN" or tone generation function on the main unit.
- Use the Wire Tracker Receiver to follow the cable path. The receiver will emit an audible tone and/or illuminate LEDs when near the cable carrying the signal.
- Adjust the sensitivity on the receiver using the rotary dial for optimal tracing.
ساتنه
پاکول
وسیله په نرم، وچ ټوکر سره پاک کړئ. د کثافاتو پاکوونکي یا محلولونه مه کاروئ.
ذخیره کول
وسیله په یخ او وچ ځای کې د مستقیم لمر وړانګو او سختو تودوخې څخه لرې وساتئ. که چیرې د اوږدې مودې لپاره ذخیره کوئ، نو د لیکیدو مخنیوي لپاره بیټرۍ لرې کړئ.
د بیټرۍ بدلول
Replace batteries when the low battery indicator appears on the display. Dispose of old batteries according to local regulations.
د ستونزو حل کول
| ستونزه | احتمالي لامل | د حل لاره |
|---|---|---|
| وسیله فعاله نه ده. | مړه یا په غلط ډول نصب شوي بیټرۍ. | بیټرۍ بدل کړئ یا سم قطبي والی ډاډمن کړئ. |
| Inaccurate cable length readings. | Incorrect NVP (Nominal Velocity of Propagation) setting; cable not fully disconnected. | Adjust NVP setting according to cable type; ensure cable is open-ended for TDR measurement. |
| Wiremap shows errors (e.g., open, short). | Actual cable fault; poor connection. | Inspect cable for damage; re-seat connectors firmly. |
| No PoE detection. | No PoE supply on the line; incorrect port used. | Verify PoE source; ensure cable is connected to the dedicated PoE port on the tester. |
