Fluke 1577 Insulation Tester and Multimeter
The Fluke 1577 is a handheld measuring instrument that combines two functions in one device: an insulation tester and a true RMS digital multimeter. In practice, this means that you can both check the insulation resistance in installations and simultaneously measure common electrical quantities with the same instrument.
This makes it relevant when working with troubleshooting and maintenance on, for example, motors, generators, cables, and switchboards, where there is a need to assess both wiring and insulation. The insulation test can be performed at 500 V and 1000 V, and the measuring range for insulation resistance goes from 0.1 MΩ to 600 MΩ. This is a range that suits typical tasks where you need to check if the insulation is holding up or if there are early signs of failure.
As a multimeter, it can be used for daily electrical measurements, and the true RMS function is an advantage when measuring signals that are not perfectly clean and uniform. The instrument is also classified for CAT III 1000 V and CAT IV 600 V, so it is designed for working in environments where there can be high voltages and stricter safety requirements.
Included accessories are a remote probe, test leads, alligator clips, a hard case, and four AA batteries. This makes it easy to take on the job and have the necessary accessories gathered in one place.
