The Kewtech KT63DL Multifunction 5 in 1 Tester is suitable for testing and certifying both household and commercial electrical installations since it crams a lot of functionality into a straightforward, user-friendly design. With an auto discharge feature, the device can test insulation up to 1000V, range continuity measures up to 2000, and fully test all RCD types with no trip loops.There are no bangs during testing, including during the auto test for RCDs up to 30mA, thanks to the simultaneous display of PSC/PFC data, loop impedance, and innovative anti-trip loop testing technology. These outcomes include a low vulnerability to RCD uplift and noise interference, and a ramp test feature is also integrated for optimal reliability. The KT63DL can perform mains polarity tests, can auto-null test leads for continuity, and is completely protected against phase to phase connection. Along with increasing the instrument's efficiency, a built-in instant correct wiring status check and independent hands-free mode controlled by a separate button also increase the operator's safety. With a tactile interface made out of easy-press buttons and a single rotary dial for function selection, the IP65 rated housing is portable and ergonomic. The KT63DL comes with an end of line calibration certificate, an ACC063 3 wire distribution board test lead and a soft carrying box.
