Kewtech KT66DL 12-in-1 Digital Multifunction Tester

Kewtech KT66DL Multifunction Tester: 12-in-1 Testing Solution

The Kewtech KT66DL Multifunction Tester is a versatile 12-in-1 testing solution, fully compliant with the 18th edition regulations. Designed for professional electricians, it’s ideal for testing domestic, commercial, and industrial electrical installations, as well as electric vehicle (EV) charge points when paired with the KEWEVSE adaptor.

Key Features:

Continuity: Ranges of 20/200/2000Ω, 200mA/15mA, with a switchable buzzer and auto null function.
Insulation Testing: Voltages of 100/250/500/1000V, bar graph display, DAR/PI function, and full discharge indication.
High Current Loop: For systems ranging from 55V to 500V, with 25A 0.001Ω and 6A 0.01Ω ranges.
Low Current Loop: Includes 2 and 3 wire options with a max Zs table for enhanced precision.
PSC/PFC Testing: Dual display for 2000A/20kA PSC and 2000A/50kA PFC, with voltage and frequency (Hz) measurements.
RCD Testing: Covers multiple types, including Type AC, ACS, A, AS, F, and electric vehicle Type B.
Voltage Measurement: TRMS 2-600V, including phase voltages and frequency.
Earth Resistance: Options for 2-wire and 3-wire testing with a live circuit warning.
SPD Testing: With a 1000V range and AC/DC breakdown results.
Phase Rotation: Clear phase-to-phase voltage indication and frequency measurements.
PAT Testing: For continuity, insulation, and easy downloading of results.

Advanced Anti-Trip Technology (ATT)

Kewtech’s Anti-Trip Technology (ATT) ensures safe loop testing on RCD circuits, offering no-trip 2 and 3 wire options. This is particularly useful in installations where no neutral is present, such as 3-phase motor lines or lighting circuits.

EV Charge Point Testing

The KT66DL, paired with the KEWEVSE adaptor, offers complete testing for electric vehicle charging equipment. It’s compatible with Type B RCDs, 6mA residual direct current devices (RDCD), and supports both TN and TT installation types. The adaptor also allows for CP and PP state adjustments, error simulation tests, and oscilloscope output for a comprehensive functionality check.

Conclusion

The Kewtech KT66DL is a highly sophisticated multifunction tester that provides electricians with a full range of testing capabilities, including those required for EV charge point installations. For a complete testing solution, it offers unmatched versatility and compliance with modern standards.
