The built-in sensor detects the presence of AC voltage without requiring direct contact. When voltage is detected, both the \u003cstrong\u003eLED indicator lights up and the audible buzzer sounds\u003c\/strong\u003e, providing an immediate dual alert.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this tester pen find wire breakpoints?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The breakpoint-finding function allows you to trace along a wire and pinpoint exactly where a break or fault occurs in a circuit. This makes troubleshooting damaged or faulty wiring much faster and more precise compared to traditional methods.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this voltage tester suitable for beginners and professionals alike?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely.
