Its bright green power LED confirms the tester is active; when voltage is present the indicator flashes red and an audible alarm sounds. Built to Klein Tools’ long-standing professional standards, this pen-style tester balances lightweight portability with rugged features like 2 m (6.6 ft) drop protection and CAT IV 1000V safety rating.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this tester show voltage so I can trust the result?\u003c\/h3\u003e\n\u003cp\u003eThe NCVT1P uses non-contact sensing to detect alternating current and communicates results with both visual and audible signals for clear confirmation.
