Fluke 1664FC Multifunction Installation Tester

FLUKE CONNECT INSTALLATION TESTER W/INSULATION PRE-TEST, US

  • 1664FC Multifunction Installation Tester with Insulation Pre-Test
  • 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 >50 V, indicating potential dangerous situations
  • Supplied with the safety designed SureGrip™ test leads and clips which gives the user a comfortable, reliable grip and consistent results
  • Rotary dial knob indicates clearly which function is selected, all in one spot with no complex multi-level menus
  • Large display with backlight, clear symbols and with exceptionally wide viewing angle for easy and safe readings
  • PASS/FAIL indication for RCD test results
  • Variable RCD current mode for customized settings
  • Loop & line resistance with mΩ resolution
  • Test smooth dc sensitive RCDs (Type B)
  • Extended memory with 3 layers
  • Use continuity test currents to measure motor windings
  • Withstands a drop of 1 meter
  • Compact, lightweight (less than 1.3 kg) and padded neck-strap to free your hands for all day testing

Fluke 1664FC Multifunction Installation Tester

Extended memory with 3 layers
Variable RCD current mode for customized settings
Use continuity test currents to measure motor windings
Z-max memory for loop tests - easy evaluation of the highest loop test value

The 1664 FC puts more power in your hands by quickly and efficiently testing to all local regulations, protecting appliances that may be inadvertently connected to the system under test, and making it easy to share test results over your smartphone.

Fluke 1660 Series Multifunction Installation Testers

Reduce test time up to 40 % with Auto Test
Auto Test does 5 required installation tests in one sequence, including selectable Type A, AC & RCD Auto Test, ensuring compliance with local installation regulations. It reduces the number of manual connections, decreases the possibility of making errors, and reduces test time up to 40 % from previous Fluke models.

Insulation PreTest

Protect the installation. Avoid costly mistakes.
The Fluke 1664 FC Installation Tester is the only installation with “Insulation PreTest,” which warns you about potentially serious and costly mistakes. If the tester detects that appliances are connected to the system during the test, it will stop the insulation test and provide a visual and audible warning. This helps eliminate accidental damage to peripheral equipment and keeps your customers happy.

Fluke Connect®, ShareLive™ calling, and Fluke Cloud™ storage

Share from anywhere
Save time - eliminate data entry by wirelessly syncing measurements directly from your installation tester and share it with your team using the Fluke Connect system. Having access to measurements simultaneously at the inspection site and from the office or an off-site location enables faster decision making and real-time collaboration between team members.

Fluke Cloud™ storage

Retrieve stored results from anywhere
Cloud storage allows you to retrieve stored results whether you are in the office or in the field to make decisions in real-time. Fluke Connect uses radio-enabled test tools and a mobile app to transfer measurements straight from the field to a secure cloud location, where the data can be accessed by team members. Plus you can import the data into Fluke DMS to process and generate certificates.
