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.

Features

With auto-test run the test of line and loop impedance, RCD tripping current and tripping time as well as insulation tests with a single connection and by pressing a single button.
Additional mode with a high test current for the loop impedance measurement. Faster output of the measurement results in comparison to the loop impedance measurement without tripping the residual current protective device (RCDs).
Z-Max-memory for easy evaluation of the highest measured value of loop tests - the loop testing.
Unique zero adapter for fast, always reliable and accurate compensation of test leads and power measurement line.
Fast voltage measurement (L-N, L-PE and N-PE) via the mains cable. Measuring inputs must be replaced.
Measure the RCD tripping current and tripping time, at the same time (RCD-type AC and A).
Two measurements simultaneously and double display PEFC or PSC and loop impedance can be measured and displayed in parallel at the same time, allowing you to save time.
Select the required input sockets via softkeys - it is not necessary, test leads.
Automatic Start for loops and RCD testing - The tests start as soon as the mains voltage is stable.
Detects increased voltages to ground from 50 V and shows potentially dangerous situations.
With the for highest security developed SureGrip™ test leads and terminals supplied to provide the user with a comfortable, reliable and consistent results.
On the basis of the position of the rotary switch is clear to see which function is set. This switch is used to select all functions, without having the complicated multi-step menus.
Thanks to the large display with background lighting, unique symbols and particularly large viewing angle the measured values can be read well and safely.
Display of the test results of RCDs using good/bad indicators.
Power for the testing of residual-current devices (RCDs) adjustable for custom settings.
Loop and line resistance with mΩ resolution.
Check of direct-current-sensitive RCDs (type B).
Extended memory with 3 layers.
Continuity test used to measure currents to motor windings.
Can withstand a fall from 1-m height
Compact, lightweight (less than 1.3 kg), with an additional padded carrying strap, allowing you to keep your hands free and so the full-time measurement work easier.
