John-

I built one of your Blue ESR meter kits and am impressed with it.

Somewhere I read that there is an industry specification or common
practice, that requires ESR measurement to be made at 100 KHz. If it is
in fact a "standard" method, you should petition that standards
committee to agree that your method is equivalent.

I have not heard of any such industry specification but will
investigate and report back to this group.

Does anyone else have any insight into this?
