Key Features:
The Fluke 1577 Insulation Multimeter combines a digital insulation tester and a true-rms digital multimeter in a single handheld instrument. Fluke designed it for electricians and maintenance professionals who need versatile troubleshooting and preventative maintenance capabilities.
The Fluke 1577 performs insulation resistance tests up to 600 MΩ using 500 V and 1000 V test voltages. As a result, users can evaluate motors, generators, cables, switchgear, and electrical installations with confidence.
In addition to insulation testing, the instrument measures AC/DC voltage up to 1000 V, AC/DC current up to 400 mA, resistance, continuity, and DC millivolts. Therefore, technicians can complete a wide range of electrical tests using one compact device.
Live circuit detection prevents insulation testing when voltage above 30 V is present. The automatic discharge function also removes stored capacitive voltage after testing, improving user safety.
The large backlit display provides clear readings in low-light environments, while true-rms measurement technology delivers accurate results on modern electrical systems. Furthermore, the rugged design withstands demanding industrial and commercial applications.
With its CAT III 1000 V and CAT IV 600 V safety ratings, the Fluke 1577 provides dependable performance for everyday electrical testing. For professionals who require both insulation testing and multimeter functionality, the Fluke 1577 offers a practical all-in-one solution.
