This is my attempt to make a 'video user's manual' for the EZM Electronics Studio model ESR-2501C "ESR Meter". This is a widely available and affordable meter for measuring the ESR (Equivalent Series Resistance) and DCR (DC Resistance) of capacitors. Unlike some other inexpensive ESR meters, it includes an appropriate case (rather that just a circuit board), and its has better accuracy than many others, and it also measures DCR (many are just ESR). Another plus is that it comes with a small array of different test probes/test clips for various ways of connecting to capacitors. It is also able to measure capacitors 'in circuit' and 'out of circuit'. The main downside is that the manufacturer provides absolutely no documentation on how to use the product; nothing of the sort comes in the box and I could find nothing online. There were only a couple videos about this product on KZfaq, and they were not useful. So, I learned how to use it, corresponded with the manufacturer, and did a lot of experiments to reveal as many details as possible, and rolled all of that into this video. I also wrote a 10 page User's Manual and a 'Quick Guide' card which can be glued to the rear of this meter's case; both are available as PDF downloads from the following fileshare webpage (look under the "EZM Electronics Studio" heading in red text):
