Fluke 1662 Multifunction Testers

The Fluke 1662 Multifunction Installation Tester is a reliable and easy-to-use tool designed for professional electricians who need accurate, day-to-day installation testing. Built with Fluke’s renowned quality, the 1662 provides all the essential features to verify electrical installations, ensuring compliance with local regulations while simplifying your workflow.

Equipped with advanced capabilities, the tester performs essential measurements such as voltage, frequency, insulation resistance, loop impedance, and motor winding continuity. It also calculates Prospective Earth Fault Current (PEFC) and Prospective Short-Circuit Current (PSC), providing a complete safety analysis of electrical systems.

The 1662 includes automatic RCD testing with ramp functions, measuring RCD trip time, trip current, and switching level for both Type A and Type AC RCDs. Its Z-max memory enables quick evaluation of the highest loop test value, while the unique zero adapter ensures fast, reliable, and accurate compensation for test leads and mains cords.

Practical usability is at the heart of its design, featuring a phase sequence indicator, auto-start functionality for RCD and loop testing, and a self-test mode to ensure measurement accuracy. The tester comes in a durable carrying case with a padded strap and remote probe, making it a complete solution for professionals working on-site.

Whether you’re handling domestic, commercial, or industrial installations, the Fluke 1662 ensures accurate, safe, and efficient testing every time.
