The ESR Meter is basically an AC Ohmmeter with special scales and protective circuitry. It provides a continuous reading of series resistance in electrolytic capacitors. It operates at 100 kHz to keep ...

The schematic of this meter was published in an Italian magazine Nuova Elettronica No. 212. I found it more than five years ago on Talino Tribuzio's IZ7ATH site when I was looking for a simple ESR ...

[Peter Demchenko] wanted to use a low power TS555 in an ESR meter design. The problem is, he needed to handle significant current sink requirements for cases where the capacitor under test had a ...

using an ESR meter or an oscilloscope. ESR is the sum of all the resistive elements in an inductor, including the wire, the core, and the solder joints. ESR is measured in ohms and varies with ...
