The Fluke 1577 is a True-RMS insulation multimeter, capable of testing voltage up to 1000V and insulation resistance up to 600MΩ. The meter features useful features such as a large display with backlight, an automatic power-off function to save battery, and a live circuit detection for added user protection. To simplify work in difficult and crowded places, this meter includes a remote measuring probe, and is compatible with the optional TPAK magnetic hanger. These features make the Fluke 1577 ideal for technicians and engineers who are looking for an insulation resistance meter and need simplicity, accuracy, and reliability. If you are looking for an all-in-one insulation multimeter, consider the Fluke 1587 FC, which is the upgraded version of this multimeter and provides more functionality at a slightly higher cost.
