Avoid damaging connected appliances during insulation tests with Fluke’s 1664 FC Installation Tester. The 1664 FC uses Fluke’s own patented Insulation PreTest which prevents tests from being performed with appliances that are connected to the system during the testing process, reducing incidents of accidental damage.
The Fluke 1664 FC is part of Fluke’s family of wireless test tools. Now, data communication and analysis is easy and more efficient. Readings and data can be communicated to team members in the field from most smartphones. The Fluke Connect software is compatible with the iPhone models 4S and higher running iOS 8.0 or higher, iPad Air and iPad Mini (2nd generation) in an iPhone frame on iPad and iPod Touch (5th generation), HTC One and One M8 running Android 4.4.x or higher, LG G3 and Nexus 5 running Android 4.4.x or higher, Samsung Galaxy S4 running Android 4.3.x or higher, Samsung Galaxy S5 running Android 4.4.x or higher and works with now over 30 different Fluke products. The Fluke Connect family offers the largest system of connected test tools in the world. Please see out Fluke Connect category for the complete collection of Fluke Connect Products. Take me to Fluke Connect (Click Here).
The 1664 FC also allows test results to be saved to Fluke Cloud™ storage. The advanced technology of cloud storage eliminates the need to manually hand write results decreasing room for error. Fluke Cloud™ storage quickly and safely stores data and even has the capability to create test certificates with Fluke DMS.
Set up and sustain preventive maintenance procedures easily using the Fluke Connect® system of wireless test tools and asset management software.
