Description

Product Details:

The Kewtech KT66DL 12-in-1 Multifunction Tester is a comprehensive and versatile test instrument with advanced memory, rotary dial, four function buttons, and an extra-large (3.5”) dot-matrix colour display. It is equipped with several auto-test functions and supports loop testing with three- and two-wire low current options, RCD testing, and EV charging point testing as well as the following:

  • ATT (Anti-Trip Technology) Loop: no-trip LOOP L-PE testing on all RCDs; two-wire option in case there is no neutral.
  • Loop: high test current range of 2Ω with 0.001Ω resolution
  • Zs Limit: compares the measured result with the values stated in the Electrical Installations Standard (BS7671 – 18th Edition)
  • 55V Loop: low and high current loop test of 110V CTE circuits
  • RCD Tests: single, auto, ramp, and contact voltage test options. Suitable for checking type AC, A, F, B (General & Selective), EV, and variable RCDs
  • Earth: two- and three-wire earth resistance tests
  • Insulation Resistance Tests: 100V, 250V, 500V and 1000V tests with auto-discharge voltage
  • Continuity: 200mA and 150mA tests with a selectable buzzer
  • Phase Rotation: test three-phase lines; the sequence is clearly indicated on the display
  • True-RMS Voltage: 2-600V
  • SPD (Surge Protection Device) Test: for SPDs that use varistors
  • PAT (Portable Appliance Tester) Function: includes insulation and protective conductor resistance tests
  • Selectable Touch Voltage Test
