Product Overview

The FLUKE 1664 FC EU is a multifunction installation tester with Auto Test, Insulation PreTest, Fluke Connect compatibility and EU plug type. The Fluke 1664 FC installation tester is the only tester with "Insulation PreTest". If the tester detects that an appliance is connected to the system under test, it stops the insulation test, helping eliminate accidental damage. Auto Test performs seven tests with one press of the button, reducing the number of manual connections and decreasing the possibility of making errors. Fluke Connect allows 1664 FC installation tester to send test results to Smartphone and collaborate with others. FlukeCloud storage allows user to retrieve stored results whether in the office or in the field to make decisions in real time and also can import the data into Fluke DMS (Data Management Software) to process and generate certificates.
  • Autotest to test line/loop impedance, RCD trip current / trip time, insulation tests with a single connection and the press of a single button.
  • Additional high current loop mode. Faster measurements compared to loop tests with non-trip mode for RCDs.
  • Z-max memory for loop tests - easy evaluation of the highest loop test value.
  • Unique zero adapter for fast, always reliable and accurate test lead and mains cord compensation.
  • Fast voltage measurement between L-N, L-PE and N-PE using the mains cord. No need to change measurement connections.
  • Measure RCD trip current & trip time in parallel (RCD type AC and A).
  • Two measurements at once and a dual display. PEFC or PSC and loop impedance are measured and displayed in parallel, saving you time.
  • Ring testing - select the required input sockets with soft keys - no need to exchange test leads
  • Automatic test start for Loop & RCD tests - as soon as mains voltage is stable it starts testing.
  • Earth Volt Touchpad detects raised earth voltages greater than 50 V, indicating potential dangerous situations.
