It's trickier than you would think because that analog ammeter
and
shunt still has to pass 166 A with minimal voltage drop
Well it is not necessary to cover the whole range of baterry
capability when the testing amp range for the MAHG at low duty. It
is much narrower.
Here is what I had in mind - a three range unit, very
inexpensive - the purpose being ONLY to confirm that the other
digital readings are not way out of line.

Naudin probably has several scattered around the lab. Not as sexy
as that way-cool scope, but it is pretty hard to fool an old
ammeter.
Some time ago (the Joe Newman era, everyone agreed that this was
the way to go for determining spikey input - I hope that this
notion hasn't changed) .... nothing could be more embarassing,
from the stanpoint of having a great-looking experiment and
web-page - to find out you have made a 20-1 error - especially
when all you had to do to catcvh it well in advance, was have a
$20 meter handy.
BTW has anyone figured out how to get rid of that annoying red
advertisement on the JNL page, short of turning off Java? The
Firefox Ad-block applet doesn't see it.
