Fluke 1577 Insulation Multimeter

Fluke 1577 Insulation Multimeter

The Fluke 1577 Insulation Multimeter gives technicians a dependable solution for both insulation resistance testing and general-purpose electrical diagnostics. Compact and portable, it combines two essential tools in one unit, saving space in your kit and reducing setup time.

With test voltages of 500 V and 1000 V, the Fluke 1577 Insulation Multimeter is ideal for diagnosing insulation problems on motors, switchgear and cable systems. The built-in live circuit detection prevents testing when voltage exceeds 30 V, offering additional user safety during operation. The unit also automatically discharges capacitive voltage after testing.

Versatility and Accuracy

This device supports a wide range of measurements, including AC/DC voltage, DC millivolts, resistance, continuity, and both AC and DC current. True-RMS capability ensures accuracy even with non-linear loads. A large backlit display makes it easier to view results in dim conditions, while auto power-off helps extend battery life.

Rugged Design and Extended Use

Designed with durability in mind, the Fluke 1577 Insulation Multimeter comes with a hard carry case and remote probe for ease of use in the field. The device is rated CAT III 1000 V and CAT IV 600 V, making it suitable for demanding environments. With up to 1000 hours of battery life for multimeter use and 1000 insulation tests, it supports extended usage without frequent replacements.

Whether for preventative maintenance or troubleshooting, the Fluke 1577 Insulation Multimeter streamlines the process. It simplifies fieldwork by combining reliable performance with practical design and long battery life.
