225 popping out the exhaust, but...

Is this from your computer driven device? I just wonder how accurate it would be on such a parameter; 0.47 ohm is a LOT. Low ESR caps typically are in the 1 to 10 milliohm range.

Dang.... I just sold a GenRad 1611B that would have been perfect for measuring dissipation factor on these caps. Oh well, it was taking up space....
