• Automatically identifies IEEE 802.3af/at PoE standards; measures voltage, polarity and crossover on RJ45 ports and displays PoE type and power.
• Performs continuity testing for STP/UTP Ethernet cables; loopback test checks network card performance; built‑in lamp for dark environments.
• Inline power tester covers DC 5–60 V (0–18 W) with a testing range up to 600 m; input‑voltage protection up to 60 V and current draw ≤ 30 mA.
• Loopback port supports 10/100/1000 M NICs; runs on a 9 V battery; includes a small remote module (48×27×23 mm) for cable‑end testing.
