Fluke 1664 FC Multifunction Installation Tester

Protect appliances, share results wirelessly, perform seven tests with one touch

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. The 1664 FC also gives you Fluke Connect®, so you can send test results to your smartphone and collaborate with others. Auto Test makes performs seven tests with one press of the button, reducing the number of manual connections and decreasing the possibility of making errors.

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 an appliance is connected to the system under test, it will stop the insulation test and provide a visual warning. This helps eliminate accidental damage to peripheral equipment and keeps your customers happy.

Fluke Connect and FlukeCloud™ Storage

Share from anywhere.

Stay on the same page even when you and your team are in different places. Fluke Connect allows your 1664 FC Installation Tester to send test results to your smartphone so you can connect and collaborate with others. It’s the fastest way to let your team see what you see, helping you get approvals without leaving the field.

Retrieve stored results from anywhere

FlukeCloud™ storage allows you to retrieve stored results whether you are in the office or in the field to make decisions in real time. Plus you can import the data into Fluke DMS to process and generate certificates. Plus you get world-class data protection. Safe. Secure. Fast. More accurate. All from the power of Fluke Connect.

Auto Test reduces test time up to 40%

Auto Test performs 5 required installation tests in one sequence, 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.
