From the project

Analog ESR meter.

The schematic of this meter was published in an Italian magazine Nuova Elettronica No. 212.

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 meter circuit.

1. Fitting the circuit in an enclosure box. 2. Dual power supply battery and external.
