COMPONENT OF THE WEEEK

Fluke 1664 FC Multifunction Installation Tester

FEATURES:

✔️ Rugged, ergonomic design with a yellow-and-gray case, large rotary dial selector on the right for switching between test modes (e.g., INSULATION RISO, CONTINUITY RLO, LOOP ZL, RCD types, VOLTS, EARTH, PHASE ROTATION).

✔️ Large backlit LCD screen (currently off or in standby in the photo).
Buttons: TEST (large silver button), MEMORY, F1–F4 function keys, ON/OFF, backlight, and arrow keys for navigation.

✔️ Fluke Connect compatibility (FC model) for wireless data transfer via Bluetooth to a smartphone app.

✔️ Insulation Pre-Test (unique to the 1664 FC) — a safety feature that detects if appliances or loads are still connected and aborts high-voltage insulation testing to prevent damage.

✔️ Auto Test function — performs multiple required tests (up to 7) in a single sequence with one connection, significantly reducing test time.

✔️ Supports testing of EV charging stations (RCD type A-EV or RDC-DD for 6 mA DC residual current devices).

PRIMARY APPLICATIONS

✅ The 1664 FC is used to:Verify that fixed electrical installations are correctly wired and safe before energization or after modifications.

✅ Perform initial verification, periodic inspection, and certification of electrical systems.

✅ Test RCDs/GFCIs (residual current devices) for proper operation.
Conduct insulation testing on wiring without damaging connected equipment (thanks to Pre-Test).

✅ Measure fault loop impedance to ensure protective devices (circuit breakers, fuses) will trip quickly enough in case of a fault.
Support EVSE (Electric Vehicle Supply Equipment) testing, including special DC-sensitive RCDs.

✅ Generate compliant test reports for regulatory bodies or clients (data can be stored, shared wirelessly, or imported into software for certificates).

The 3rd delivery for the week is a diaphragm repair kit (also called a wear parts set or Verschleißteilsatz) with part number 1247732.0000.00000. It is specifically designed for the Buschjost 8493635 (a 2-inch pulse jet solenoid valve)
