Fluke 1674 FC UK Multifunction Installation Tester – Advanced Testing, Seamless Connectivity

The Fluke 1674 FC UK Multifunction Installation Tester is a high-performance electrical testing solution designed for professional electricians and contractors who demand reliability, precision, and connectivity. Built to handle the most rigorous installation environments, this advanced tester supports a full range of essential and advanced electrical tests, helping users meet UK wiring regulations and international compliance standards with confidence.

With the ability to perform insulation resistance testing across multiple voltage levels—50 V, 100 V, 250 V, 500 V, and 1000 V—the Fluke 1674 FC delivers accurate resistance measurements up to 1000 MΩ. It also features reliable continuity testing with zero lead compensation and automatic polarity reversal, ensuring consistent performance even in low-resistance circuits. For loop and line impedance, this tester offers high accuracy across hi-current, no-trip, and selective testing modes, along with fault current calculations up to 50 kA, making it ideal for both domestic and commercial installations.

The Fluke 1674 FC UK supports comprehensive RCD testing across all common RCD types, including AC, A, F, B, B+, and RDC-DD. It performs ramp testing, auto sequences, and fixed current tests (½x, 1x, 5x), providing a complete view of device behavior under fault conditions. Earth resistance testing is also included using the 3-wire fall-of-potential method, offering reliable measurements up to 2000 ohms for grounding system verification. An advanced insulation ramp test function allows for gradual voltage application to assess insulation condition or stress-test sensitive components like SPDs.

Engineered with wireless connectivity through Fluke Connect™, the 1674 FC UK enables real-time data sharing and cloud-based test result storage via a smartphone, tablet, or PC. This feature helps streamline job reporting, improves collaboration, and ensures secure documentation. A long-lasting rechargeable Li-ion battery keeps the unit running throughout the day, while the bright colour display and intuitive interface ensure clarity and ease of use, even in challenging lighting conditions.

Compact, durable, and compliant with IEC/EN 61010 and 61557 safety standards, the Fluke 1674 FC UK is the ultimate multifunction tester for professionals who require dependable performance, advanced testing capabilities, and modern data management—all in one smart, portable device.
