Fluke 1662 UK Multifunction Installation Tester

The Fluke 1662 replaces the previous Fluke 1651 and 1652 multifunction testers and conforms to the latest 18th Edition Wiring Regulations.

This entry level model MFT from Fluke is solid and reliable, designed to meet the demands of every day testing and tests to all UK regulations. The Fluke 1662 is ideal for electricians and engineers both new and experienced, thanks to its easy to use, intuitive layout and ability to carry out all the basic testing procedures required in accordance to IEC 60364.

18th edition testing made easy

The Fluke 1662 makes everyday testing as simple as possible. It features an easy to use single click rotary dial to the right and large, central backlit LCD screen. The test and function buttons are to the left in order to create an uncluttered and simple to use interface. A remote test probe is also included as well as a mains zero adapter.

Adding to the improved usability, Fluke’s new ‘plug top’ style mains test lead allows you to plug all three leads into the Fluke 1662 in one go, saving you time and providing a secure connection. This simple feature was added to the 1660 range of MFT’s as a result of feedback from Fluke users over the years. A neck strap is also included for added comfort when testing for longer periods.

9 in 1 multifunction tester

The Fluke 1662 has all the functions you need for the essential testing of domestic, industrial and commercial  electrical installations. The 1662 is also suitable for certifying fixed wiring in accordance with the requirements of IEC 60364 and relevant local standards.

True RMS AC/DC voltage and frequency measurements

  • TRMS measurement up to 500V
  • Achieve reliable results even on noisy circuits

Continuity measurement with auto-null feature

  • Simply touch the test leads together and press the zero button
  • Test lead resistance is measured and stored for more accurate results

Insulation resistance testing

  • Selectable 100, 250, 500 and 1000V test ranges
  • Allows for the safe testing of a wide range of installations
  • Live voltage indicator to warn the user if a live voltage is pressent

Polarity test

  • The 1662 tests for correct polarity using the continuity mode.
  • Detects broken PE and N wires

Phase sequence indicator

  • Quickly detects and displays phase sequence

RCD testing

  • Selectable trip current rating, test current multiplier and RCD type
  • Testing is carried out for both 0 and 180° phase settings
  • Auto mode and temporary memory remove the need to return to the installation tester when the RCD trips

Loop testing

  • Patent pending no trip technology for consistent and highly repeatable results

Prospective Fault Current (PFC)

  • Calculates PFC using either three separate test leads or mains lead
  • Result is displayed in the lower part of the display

Prospective Short Circuit (PSC)

  • Calculates PSC which could flow when there is a short circuit between line and neutral
