Maintenance

Overview

The Triplett LVPRO10 is a handheld TDR (Time-Domain Reflectometer) cable tester designed for copper cables, including CAT 5E, CAT 6, CAT 6A, and CAT 8. Its primary function is to detect and diagnose wiring conditions of twisted-pair and coaxial cables. This versatile tool can identify network service issues, short/open circuits, split pairs, and mis-wires within network cabling. Additionally, it can detect the presence of Power over Ethernet (PoE) supply and identify PoE standards (802.3AF, 802.3AT, 802.3BT). The device is characterized by its accuracy, ease of operation, and clear visual display, making it an ideal tool for network communication maintenance, engineering, and wiring.

Function Description

The LVPRO10 offers several testing modes and functions:

  • Testing Mode (TEST): This mode is used for comprehensive cable testing.

    • Twisted-Pair Cabling Test: The tester can perform a cabling test on RJ45 ports. It runs continuously once connected to the cabling and a wire map adapter. It provides accurate cable length measurements without a remote adapter, though an adapter is needed for a complete wire map test.
      • Open Circuit Detection: If a wire is open, the display shows the approximate distance to the open circuit and the total cable length. The warning icon appears if only one wire in a pair is open, but not if both are open, as open pairs can be normal in some applications.
      • Short Circuit Detection: The tester identifies shorts between wires, with the shorted wires flashing on the display. When a short is detected, the far-end adapter and mapping of unshorted wires are not shown.
      • Crossed Wires Detection: The device can detect crossed pairs, indicated by flashing pin numbers. A far-end adapter is required for this test.
      • Split Pair Detection: The tester identifies split pairs, where continuity is correct but wires from different pairs are used, causing excessive crosstalk. The symbol and "SPLIT" flash to indicate this fault. Cables with untwisted pairs, like telephone cords, often show split pairs.
      • Ethernet Port Detection: The tester can detect an Ethernet port. However, it may not measure length accurately if the port does not produce reflections or if its impedance fluctuates.
      • PoE Switch Detection: In testing mode, the LVPRO10 can identify if a connected device is a PoE switch, displaying "POE" and a warning icon. It cannot identify specific IEEE 802.3af, 802.3at, or 802.3bt standards in this mode; for that, the PoE mode should be used.
      • Voltage Detection: The tester detects cable voltage. If the measured cable is live and its voltage is 10V or greater, it displays a warning icon and "Pn" (P for positive, n for negative).
      • Detailed Wire Pair View: Users can view detailed results for each wire pair, moving through screens to see specific issues like shorts or open circuits and their distances.
    • Coaxial Cabling Test: The tester can switch to coaxial test mode to check coaxial cables. It connects to the cabling via an F-connector or an adapter/hybrid patch cord.
      • Good Coaxial Cable Results: Displays the length of a good coaxial cable terminated with a far-end adapter.
      • Open on Coaxial Cabling: Shows the distance to an open circuit on a coaxial cable.
      • Short on Coaxial Cabling: Indicates the distance to a short circuit on a coaxial cable.
      • Voltage on Coaxial Cabling: Displays a warning icon if the coaxial cable is live and its voltage is 10V or greater.
  • PoE Mode (POE): In this mode, the tester identifies the presence of PoE and its standard (af/at/bt). It detects PoE on pairs 1,2-3,6 and 4,5-7,8 and is designed not to be damaged by PoE sources. If PoE is detected, "POE" appears above the powered pairs and may blink if the PoE source cycles power. The tester can identify IEEE 802.3af, IEEE 802.3at, and IEEE 802.3bt standards. For non-standard PoE devices, users need to switch to TEST mode to check for power.

  • Tone Mode (SCAN): This mode is used for wire tracking.

    • Tone Mode Display: The default display shows the tone mode.
    • Hub Blink Function: This function can be enabled or disabled, causing the switch port indicator light to flash synchronously if connected to a working switch.
    • Signal Generation: The tester sends a 125KHz digital modulation signal (10VPP) to support the LVPRO10 receiver for tone function.
  • LVPRO10 Receiver (Wire Tracker): This accessory works with the LVPRO10 tester to locate and isolate cables by adjusting sensitivity.

    • Twisted-Pair Wire Tracking: Connect the tester to the line, set it to "SCAN" mode, select RJ45 port, and enable the hub blink function. The receiver's sensitivity knob helps locate the cable by producing "Beep--Beep--Beep" sounds.
    • Coaxial Cable Tracking: Similar to twisted-pair tracking, but for coaxial cables.
    • Wire Tracking Diagram: When tracking a cable among many others, adjusting the sensitivity helps identify the target cable, with higher sound volume indicating proximity.
    • NCV Function: Pressing the "NCV" button enables non-contact voltage detection. If the targeted cable or receptacle voltage is greater than 40V (AC), the receiver beeps and the NCV indicator light flashes.
    • Flashlight: A dedicated button activates the flashlight function.
    • Earphone Support: For noisy environments, earphones can be used to minimize interference and adjust sound volume (earphones not supplied).

Usage Features

  • Intuitive Controls: The device features a mode knob (Wire tracking, testing, PoE), a power button, and multiplexed buttons for viewing test results.
  • Clear Display: An LCD display with backlight shows all relevant information, including tester icon, detail screen indicator, active port, tone mode indicator, numeric display with units (feet/meters), test mode indicator, PoE mode indicator, short circuit indicator, telephone voltage indicator, wire map adapter connection indicator, low battery indicator, Ethernet port indicator, wiremap diagram, and fault/high voltage indication.
  • Unit Switching: A short press of the unit button switches between feet and meters.
  • Backlight Control: A long press of the unit button (about one second) turns the backlight on or off.
  • Software Version Display: Pressing the unit and power buttons simultaneously displays the software version.
  • NVP Calibration: The tester allows calibration of length measurements by setting the Nominal Velocity of Propagation (NVP). This can be done by entering NVP setting mode, selecting the port, and adjusting the NVP value using the navigation buttons. The NVP can be set to a specified value or determined by connecting a known length of cable and adjusting the NVP until the measured length matches the actual length. This feature enhances measurement accuracy.
  • Auto Power Off: The tester automatically powers off after 10 minutes of inactivity (60 minutes in wire tracking state) to conserve battery.
  • Low Battery Indication: A low battery symbol appears when the battery needs replacement, ensuring test accuracy.

Maintenance Features

  • Cleaning: The display should be wiped with a soft cloth and glass cleaner, while the casing can be cleaned with a soft cloth dipped in clear water or liquid soap. It is important to keep the tester dry. Solvents or corrosive cleaning agents should not be used as they can damage the device.
  • No User-Serviceable Parts: The casing should not be opened, as there are no user-serviceable parts inside. Opening the case without authorization voids the warranty and may compromise safety.
  • Replacement Parts: Only designated replacement parts should be used for any repairs.
  • Troubleshooting:
    • If the tester does not power on, replace the battery.
    • If measurement length is inaccurate, check and adjust the NVP using a cable with a known length.
    • If the display or buttons are unresponsive, power off and restart the tester.
