The Kyoritsu 6516BT Multi Function Installation Tester is a professional, all-in-one solution designed for electricians, inspection engineers, and electrical maintenance specialists. With its vibrant 3.5-inch color LCD display, it provides clear, real-time data, allowing faster, more accurate decision-making in the field. Furthermore, the intuitive display guides users through multiple functions effortlessly, therefore improving operational efficiency and reducing setup errors.
Moreover, the innovative Anti-Trip Technology enables LOOP L-PE testing without tripping RCDs, so it is suitable for both standard and no-neutral installations. In addition, the tester delivers comprehensive measurement capabilities, including LOOP, RCD, earth resistance, insulation resistance, continuity, phase rotation, voltage, SPD, and PAT testing, which ensures full compliance with electrical installation standards. Also, it supports multiple RCD types—AC, A, F, B, EV, and Variable—and provides single, auto, ramp, and contact voltage testing modes, thus offering versatile performance for a wide range of installation scenarios.
Additionally, Bluetooth® connectivity via the KEW CONNECT app and the on-screen HELP guides improve usability, so users can transfer data and follow proper testing procedures seamlessly. Finally, with IEC 61010-1 CAT IV 300V / CAT III 600V and IEC 61557 compliance, this tester guarantees professional-grade reliability, making it an essential tool for precise electrical diagnostics, certification, and installation verification.
