Got it. Thanks,
This seems to be the schematic of the "ESR Meter", which appears in many
places on the web, but the urls in my current archives have expired so I
can't post them for reference.

This is a design from 1980, probably good when the typical ESR was 10 ohms
or more. It no longer applies to current technology.

We need new technology for the second millenium. The first millenium won't
work anymore.

We need three digits full scale with 1.0mR resolution. Measures any
embedded ESR in capacitors (AC to 1.0MHz), inductors (both AC to 1.0MHz and
DC) or any resistors. That puppy would hunt.


How much would you or others be ready to pay for this?
