The 1664 FC offers you extensive testing capabilities to quickly and efficiently test all local regulations, protect devices, and share test results in real-time via your smartphone. The Fluke 1664 FC is the only tester with "Insulation PreTest," which stops the insulation test and issues a visual warning when it detects that a device is connected to the system being tested. This helps you avoid potentially serious and costly mistakes that could damage your customers' peripherals. Auto Test conducts up to seven installation tests in sequence, ensuring compliance with local installation regulations. This reduces the number of manual connections, thereby decreasing the possibility of errors and shortening test time. Since the 1664 FC is Fluke Connect-enabled, you can send test results to your smartphone, store them in the cloud, and share measurements in real-time through a ShareLive video call with team members. This is the fastest way to show your team what you see and help you obtain approvals without leaving the field. With Fluke Cloud storage, you can access saved results whether you are in the office or on the go, allowing you to make real-time decisions. You will receive top-notch data privacy and can import the data into Fluke DMS (Data Management Software) to process and generate certificates.
