Description

Product Details:

This latest series of multifunction installation testers adds one to the nomenclature and vastly to the value of these testers. The range of 3 instruments is expressly for testing low voltage electrical installations to BS7671. They provide all the tests required to complete the necessary electrical certification for industrial, commercial and domestic fixed wiring installations.

MFT1721, the most popular of the range of 18th Edition testers, with auto RCD testing and phase rotation, 3-phase RCD testing and current measurement with the optional clamp.

With an additional 100V insulation test range, true RMS voltage measurement, mV sensor input and Type B RCD testing.

Key Features:

  • System voltage and frequency measurement TRMS „
  • Insulation test at 100 V, 250 V, 500 V and 1000 V Including input protection against live circuits up to 600 V even when insulation test is locked-on „
  • Continuity resistance at 200 mA or 15 mA „
  • Automatic start – no need to press TEST so leaving both hands free to hold probes „
  • Resistance range up to 100 kΩ with fast continuity buzzer at selectable thresholds „
  • Earth loop test „
  • 2 and 3 wire non-trip range „
  • 2 wire Hi current including phase to phase „
  • Prospective fault current measurement up to 20 kA „
  • RCD testing
