It checks all 8 conductors for open circuits, short circuits, and crossed wiring.\u003c\/p\u003e\n\u003ch4\u003eQ: What does the POE anti-burn protection actually do?\u003c\/h4\u003e\n\u003cp\u003eA: Power over Ethernet (POE) networks carry electrical power alongside data. Without protection, connecting a tester to an active POE port could damage the tester or the network equipment. The built-in anti-burn circuit automatically limits overvoltage and overcurrent, keeping both your tester and your devices safe during live-line testing.\u003c\/p\u003e\n\u003ch4\u003eQ: Does this tester require batteries, and how do I read the results?\u003c\/h4\u003e\n\u003cp\u003eA: The tester does not include batteries in the package — please check the unit for its power requirements before use. Results are shown via onboard LED indicator lights: each light corresponds to a specific wire pin, so a quick visual scan immediately tells you which conductors are correctly wired, open, or shorted — no software or screens needed.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this tester suitable for testing telephone lines as well as LAN cables?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely. The tester includes an RJ11 interface specifically for telephone line testing, letting you verify continuity and pinout on standard phone cables in addition to LAN and HDMI cables — making it a truly multifunctional tool for any wiring job.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Can this network cable tester check all types of Ethernet cables including Cat5, Cat6, and Cat7?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes — the tester uses an RJ45 (8P8C) interface, making it compatible with Cat5, Cat5e, Cat6, and Cat7 Ethernet patch cables and bulk cables.
