The Kewtech KT64DL has a loop testing circuit and continuously monitors live voltage, protecting users when conducting dead tests. The Anti-Trip Technology (ATT) ensures accurate loop testing of RCD-protected circuits, and the auto RCD test mode simplifies the process, with test results for Type AC, A, ACS, AS, auto, and ramp RCDs.
It supports various RCD test values, including 10mA, 30mA, 100mA, 300mA, and 500mA. It also has a single rotary dial, a large screen display, and an IP54 rating.
The unit also includes ultra-slim and gold-plated probe tips, continuity testing with a switchable buzzer and auto-null, insulation testing at 250V, 500V, and 1000V with voltage warning and auto discharge, and high-precision loop testing with low and high current options.
Additional KEWEVSE or KEWEVA required.
The magnetic base allows for hands-free attachment to metal cabinets and distribution boards.
