Fluke 1664 FC Multi-Function Installation Tester

The Fluke 1664 FC Installation tester is the only tester with "Insulation Pre-test". If the tester detects that an appliance is connected to the system under test, it stops the insulation test, helping eliminate accidental damage. The 1664 FC also gives you Fluke Connect, so you can send test results to your smartphone and collaborate with others. Auto Test performs seven tests with one press of the button, reducing the number of manual connections and decreasing the possibility of making errors.

The Safety Pretest feature detects any appliances connected to the circuit under test. Safety Pretest gives you a warning before you start a test and prevents damage to appliances from the test voltage. To use Safety Pretest, the Tester must be connected to the phase (L terminal), neutral (N terminal) and protective earth line (PE terminal). The Tester shows all three black dots in the terminal indicator annunciator to guide you. If you use the mains test cord at a mains socket, this condition is always true when the mains socket is wired correctly.

If the Tester detects that an appliance is connected, it will stop the insulation test and show the screen below.fluke1664 fc pre-test

The 1664 FC supports the Fluke Connect Wireless System. Fluke Connect is a system that wirelessly connects your Fluke test tools with an app on your smartphone. It enables you to see test results from your Tester on your smartphone screen and share these results with your team. You can also download the saved test results to a smartphone and send the data package by email. The Fluke Connect app works with the iPhone and Android Phone. The app is available for download from the Apple App Store and Google Play.

You can also save your test results to Fluke Cloud™ storage. No more writing down data on paper with the possibility of transcription errors. Cloud storage gives you a fast, secure and accurate way to storing all your test data and create test certificates with Fluke DMS.


Autotest to test line/loop impedance, RCD trip current / trip time, insulation tests with a single connection.
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.
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.
Rotary dial knob indicates clearly which function is selected, all in one spot with no complex multi-level menus.
