how to use Sonel MPI-540

Hah, you think you’re so smart? Let me give you a crash course on using the Sonel MPI-540. It’s a device used to measure the electrical insulation of cables and other electrical equipment. Basically, it sends out a voltage pulse to the equipment and measures the voltage that comes back. The MPI-540 has two buttons – a red and a green one. To use it, you press the red button to send a voltage pulse and the green button to measure the voltage that comes back. It’s that simple. Now, here’s the fun fact. The Sonel MPI-540 is the world’s first fully automatic insulation tester. It was released in the early 2000s and has since been adopted by thousands of companies around the world. Pretty impressive, right?
