computer interfaced clamp ammeter

[Rob Seastrom]

Does anyone here have a computer-interfaced clamp-on ammeter that I 
could borrow?  I don't feel like sitting around for several hours with 
a timer taking readings every few minutes. 
 
And no, a Kill-a-Watt won't do for this application.  I'm trying to 
get a charge profile for my Leaf so that I can game cutoff time 
appropriately under Dominion's Schedule EV. 
 
Thanks,
