Fluke 1674 Multifunction Installation Tester

The Fluke 1674 Multifunction Installation Tester is an essential tool for electrical testing in domestic, commercial, and industrial environments. Designed to meet IEC/HD 60364-6 requirements, this tester offers a comprehensive range of tests. It includes unique functions such as insulation monitoring, surge protection testing, and high-resolution loop and line impedance measurements. With a full-colour screen and rotary dial, the 1674 provides an intuitive interface for efficient and reliable testing.

This device enhances productivity by performing installation tests up to 30% faster. The Auto Test function automates the entire test sequence, minimising repetitive setups and reducing errors. Additional features like automatic measurement validation and user-defined limits ensure accurate, reliable results with an immediate pass/fail indication. The Fluke 1674 streamlines your testing process, whether you’re measuring loop impedance, resistance, or checking wiring polarity.

Enhanced User Interface and Safety Features

The 1674’s touchscreen and rotary dial provide a straightforward way to customise test sequences, whether you’re working directly on the device or connected via a smart device or PC. With support for hierarchical data management through Fluke Connect™️, users can easily organise test data by client, site, distribution board, and circuit. The innovative Insulation PreTest™️ feature protects equipment by automatically stopping insulation tests if an appliance is connected, preventing potential damage and costly mistakes.

Built for versatility, the tester offers RCD testing, continuity tests with low current, and measurements of motor windings. The high loop mode allows for fast testing on RCD-protected circuits, while the Z-max memory helps evaluate the highest loop test value. Compatibility with accessories like the Fluke FEV300 further extends its functionality, enabling electric vehicle charging station tests.

TruTest™️ software simplifies data management. You can transfer data to a PC for reporting and analysis via USB-C or Fluke Connect™️. Create reports in compliance with industry standards like BS7671, making documentation and presentation of results straightforward.
