• Combines a network cable tester, wire tracer, cable‑length meter (5–200 m), PoE tester/port locator, digital multimeter and non‑contact voltage (NCV) tester.
• Wire‑map and cable‑tracing modes locate open/short/cross faults on CAT5/CAT6 cables; port‑blink function identifies switch ports (10/100/1000 M).
• PoE tester detects voltage (5–60 V) and identifies IEEE 802.3af/at standards; NCV detector provides High/Medium/Low beeps for live‑wire detection.
• Digital multimeter measures DC/AC voltage (20–400 V), resistance (0–600 kΩ) and diode continuity; auto‑off conserves the 3.7 V 2500 mAh battery.
• Transmitter: continuity test up to 2000 m; cable‑length meter 5–200 m; port scanning speeds 10/100/1000 M; size 200×73×50 mm. Receiver size 220×46×29 mm.
