An ESR meter is in effect an AC Ohm-meter designed to detect very low value resistors. This can be achieved by applying a fairly high frequency AC signal to the capacitor (100 KHz in this design) and measuring the effects of the resistive drop across the capacitor. At 100 KHz, the reactive component of the capacitor (Xc = 1/ (2*pi*f*C) ) is.

Re: Digital ESR meter design. « Reply #3 on: January 26, 2020, 05:14:42 pm ». in the schematic, Cx is connected with 2 wires only. you will never get 0.01 ohms accuracy with a 2-wires measurement. you need 4-wires. the elektor esr meter, from 2002, uses most of the same circuits, and has this 4-wires measurement method.
