Doesn&#039;t matter; the resistance across an ASE would be in the microohm range.</p><p><br /></p><p>On the other hand, it <i>does</i> measure microvolts. So if I hook the ASE up to my car battery with jumper cables, and run a few hundred amps through it, I could probably get a pretty robust voltage reading before the cables melt. (I expect the cables would melt before the ASE would, because they&#039;d be dissipating a lot more heat. They&#039;d almost certainly spot-weld themselves to the coin&#039;s surface, though.)[/QUOTE]</p><p><br /></p>
