Fluke 1663 Multifunction Installation Tester is the ideal choice for hard working professionals

The 1663 installation tester delivers the full-featured functionality and advanced measurement capabilities that professional installers need. It is compact and lightweight (less than 1.3 kg) and comes with a padded carrying and waist strap for convenient handling.

New EVSE Testing Capability for 2023

The Fluke 1663 Multifunction Tester’s firmware has been updated to support 6mA RDC-DD tests in accordance with international standards IEC 60964 and IEC 62752. Together with Fluke’s FEV300 Test Adapter, this new ability enables comprehensive, accurate, and reliable testing of electric vehicle supply equipment (EVSE). It allows you to conduct all necessary tests in one go and meet the evolving needs of the EVSE market. (EV Adapters sold separately)

On top of this new function, you can also expect all of the typical measurements you'll need such as voltage (AC/DC), frequency, wiring polarity, insulation resistance, loop/line resistance, prospective earth fault current (PEFC/IK), prospective short-circuit current (PSC/IK) and several RCD measurement modes such as RCD tyip time, ramp test (RCD trip current) and more.

Software compatible

The Fluke 1663 is compatible with TruTest™, a Fluke software designed to eliminate the hassle associated with traditional electrical system data management and reporting. Whether you are testing fixed wire installations, or appliances in an office, verifying repairs in a workshop, or performing annual inspections, proper data management is critical for producing easy-to-understand reports for clients. TruTest™ Software allows you to quickly and easily import measurement results directly from your test instruments, manage files transferred from instruments, or manually enter data as needed. (Sold separately)

Other useful capabilities:

  • NEW - 6mA RDC-DD tests according to IEC 60964 and IEC 62752
  • Checks wiring polarity to detect broken N wires
  • Measures insulation resistance and loop and line resistance
  • Includes Z-max memory for loop tests to support easy evaluation of the highest loop test value
  • Provides unique zero adapter for fast, reliable and accurate test lead and mains cord compensation
  • Measures motor windings with continuity test
  • Calculates prospective earth fault current (PEFC/IK) and prospective short-circuit current (PSC/IK)
  • Measures RCD switching time and tripping level (ramp test)
  • Measures trip time and current for RCD type A & AC in one test
  • Measures RCD variable current
  • Provides automatic RCD test sequence
  • Includes a phase sequence indicator
  • Safety rated CAT III 500V, CAT IV 300V

The ideal tester for hard-working professionals.

This instrument is ideal for professional users – full-featured functionality, advanced measurement capability, yet it is still easy to use. Operation is intuitive and easily mastered by all levels of field workers.
