Instrucțiuni de operare
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.
Detectare PoE
- 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.
