Fluke 1664 FC Multifunction Installation Tester

The Fluke 1664 FC Installation Tester is a tester that helps prevent damage to connected appliances, reduces test time and features Fluke Connect.

Incorporated is Insulation-PreTest, a feature that allows the tester to determine if system under test has an appliance connected. If an appliance is detected the 1664 FC stops the test, helping to eliminate accidental damage.

To reduce test time the 1664 FC also offers an auto test function. One button press initiates a predefined sequence of seven tests. Compared to previous Fluke models this feature can save up to 40% in time.

The featured Fluke Connect allows measurements to be sent to a centralised cloud based server, the Fluke Cloud. Data can be uploaded via a smartphone with the Fluke Connect app in real time, making it easy to record, analyse and share data with colleagues from the field.

Key Features & Benefits

• Fluke Connect compatible
• Insulation pre-test – protects connected appliances from damage
• Auto-test function – tests line/loop impedance, RCD trip current/trip time and insulation tests over a single connection with one button press
• Automatic test start for loop & RCD tests – as soon as mains voltage is stable testing commences
• 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

Additional Features

• Earth Volt Touchpad detects raised earth voltages >50 V, indicating potential dangerous situations
• 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
• Uses continuity test currents to measure motor windings
• Supplied with the safety designed SureGrip test leads and clips which gives the user a comfortable, reliable grip and consistent results
• Compact, lightweight – less than 1.3 kg
• Padded neck-strap to free your hands for all day testing
