Fluke 1577

Fluke 1577 – Overview

The Fluke 1577 is a 2-in-1 tool combining an insulation resistance tester and a true RMS digital multimeter. Designed for preventive maintenance and troubleshooting on motors, generators, cables, and switchgear, it offers high insulation test voltages, safety features like live-circuit detection and auto discharge, and a multimeter portion that covers AC/DC voltages, currents, resistance, continuity and more—all in one rugged handheld unit.

Key Features

• Insulation test voltages: 500 V and 1000 V

• Insulation resistance range: 0.1 MΩ to 600 MΩ

• True RMS multimeter for accurate AC/DC readings

• Live circuit detection: prevents insulation test if voltage > 30 V is present

• Auto discharge of capacitive voltage for safety after tests

• Full multimeter functions: AC/DC voltage, milliamps, resistance, continuity

• Large backlit display for visibility

• Rugged hard-utility case and long battery life

• Three-year warranty included
