The tricolor LED display simultaneously shows all three parameters, updated in real time. Installation involves inserting the body into the 22mm hole in the electrical panel, then connecting the cables according to the included diagram. The current transformer clamps onto the phase conductor without requiring disconnection. Installation requires certified electrician qualifications according to safety standards.\u003c\/p\u003e\n\n\u003c\/section\u003e\u003csection class=\"cl-faq\"\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use it for single-phase 220V household networks?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eYes, it works perfectly with household 220V AC, measuring voltage between 60-500V and current up to 100A, covering both residential and industrial installations.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs it necessary to cut the power to measure amperage?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eNo, the included toroidal transformer clips onto the phase conductor without interrupting the electrical circuit.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"cl-faq-item\"\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat does it mean that the LED light is visible from a distance?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eThe yellow LED display emits powerful self-light, making the values clear to read even in bright spaces or from positions 2-3 meters away from the panel.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003c\/section\u003e\u003csection class=\"cl-specs\"\u003e\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\n\u003ctable\u003e\u003ctbody\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eVoltage measurement range\u003c\/td\u003e\n\n\u003ctd\u003eAC 60 - 500V\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eCurrent measurement range\u003c\/td\u003e\n\n\u003ctd\u003e0 - 100A\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eFrequency measurement range\u003c\/td\u003e\n\n\u003ctd\u003e20 - 75Hz\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eMounting hole diameter\u003c\/td\u003e\n\n\u003ctd\u003e22mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eDisplay dimensions\u003c\/td\u003e\n\n\u003ctd\u003e31 x 31mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eLED color\u003c\/td\u003e\n\n\u003ctd\u003eYellow\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eCurrent transformer\u003c\/td\u003e\n\n\u003ctd\u003eIncluded (toroidal)\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003eDisplay type\u003c\/td\u003e\n\n\u003ctd\u003eDigital LED 3 parameters simultaneously\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003ePackage contents\u003c\/td\u003e\n\n\u003ctd\u003e1 indicator, 1 toroidal transformer\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003c\/section\u003e\u003csection class=\"cl-warranty\"\u003e\u003ch2\u003eWarranty and support\u003c\/h2\u003e\n\n\u003cp\u003eThe product benefits from a 24-month warranty in accordance with Romanian legislation. 30-day return policy.
