In this electronics basics episode we will be having a look at the biggest mistake you can do when working with an oscilloscope. But I will not only show you how to do safe mains voltage measurements but also show you all the basics when it comes to oscilloscopes. That means I will show you how to choose one, how to do simple voltage and current measurements and finally how FFT works. I will explain passive probes, triggering, voltage & time division, measuring functions, the cursor function, AC & DC coupling and single mode capturing. Let's get started!
