• Eight‑in‑one tool integrating PoE testing, cable diagnostics, continuity check, port flashing, cable‑length measurement, LED flashlight and UTP/STP verification.
• Measures cable length and fault distance (2.5–200 m) without calibration; detects open, short and cross wires; supports RJ45/RJ11 and shielded/unshielded cables.
• Provides Normal, Anti‑Interference and PoE scanning modes for tracing cables; port flash quickly identifies switch ports.
• PoE diagnostics measure voltage and identify PSE type (mid‑span/end‑span); includes VFL 10 mW and non‑contact voltage detection; powered by a 3.7 V lithium battery.
