The Fluke 1577 Insulation Multimeter is a cracking two-in-one tool for technicians working on motors, generators, cables, and switchgear, blending a digital insulation tester with a true RMS multimeter for versatile troubleshooting and preventive maintenance. It offers insulation testing at 500 V and 1000 V (0.1 MΩ to 600 MΩ, ±2% accuracy at 1000 V) and measures AC/DC voltage (1000 V, ±0.2% DC), current (400 mA, ±1% DC), resistance (50 MΩ, ±1.2%), and continuity.
Safety features include CAT III 1000 V and CAT IV 600 V ratings, live circuit detection (>30 V), and auto discharge of capacitive voltage. The large backlit display, auto power off, and optional TPAK magnetic hanger enhance usability, while the IP40-rated, 624 g device is powered by four AA batteries (1000 hours typical, 1000 insulation tests at 1000 V). Operating in -20 °C to 55 °C, it’s built for tough environments. The kit includes a remote probe, test leads, alligator clips, a rugged hard case, and batteries, with a three-year warranty. The Fluke 1577 is a reliable, efficient mate for precise electrical diagnostics at a cost-effective price.
