Comprobador PoE Fluke MicroScanner PoE negro azul amarillo RJ-45 RJ-11

The Fluke MicroScanner PoE tester is a compact handheld tester for verifying Power over Ethernet (PoE) and cable integrity on RJ‑45 and RJ‑11 connectors. Designed for field use, it performs wire continuity checks and PoE classification tests, displays results on an oversized backlit LCD, and reports opens, shorts, crossed pairs and distance to a break. Its small footprint and AA battery operation make it convenient for technicians who need quick, reliable diagnostics for network, security and building automation cabling.

Advantages

The MicroScanner PoE provides fast continuity testing of all conductors and a graphical display that indicates faults and the end of a cable run. It identifies PoE class and supports Class 1 through Class 8 devices, helping to determine switch power capacity. The device is suitable for use in harsh environments where vibration, flexing, moisture and temperature cycles can cause cable failures. The backlit screen and intuitive icons allow clear reading in bright light or complete darkness. Compact dimensions and AA battery power enable extended field use without external power.

How to use

Connect the appropriate RJ‑45 or RJ‑11 cable to the tester and power the unit with AA alkaline batteries. Select the test mode and observe the backlit LCD for graphical results showing continuity, opens, shorts or crossed pairs. For PoE testing, the unit will detect presence of power and report the PoE class. Use the distance-to-fault indication to locate breaks within the cable run. The icons and on‑screen readout guide the user through interpreting results without requiring specialized training.

Recommendations

Use the MicroScanner PoE as part of routine pre‑installation verification and periodic maintenance to detect cable degradation early. When working in wet or electrically noisy environments, ensure connectors are clean and secured before testing. For accurate distance-to-fault readings, test from one end of the cable run and avoid inline splices or patch panels between test points when possible.
