Re: Meter Shunts ??

It's seems like a pretty normal meter to me. Here's a link to where
it's sold at from allelectronics
http://www.allelectronics.com/cgi-bin/category.cgi? category=385&item=PMD-200A&type=store
But do you think the resistor ideal will work too?

200 Amp Meter, something that size is feed by a transformer, did it
have
a torrid with it?? The line carrying the load will go through the
torrid
and it will have a few windings (depending on the meter),on the torrid
to pick up current induced by the 200 amp line.

         Oh I'm talking about voltages anywhere from zero volts to
350VDC.
Then current anywhere from 0 to oh say about 500amps.
         Then of course I would like to do primary measuring so then
15KVAC
but that's a different story.

         I just wanna to know if using resistors is an efficient way of
dropping the current and voltage since it will be to high for the meter
to
handle. I have found a nice cheap 200 amp panel meter, I so can just
use
a
resistor so it can handle more current and drop the voltage, then just
recalculate that new ratio and then I know what the current is. Then do
the
same with a voltage panel meter though I will need to get one that
reads

like mVDC since I will need a big meaty resistor.
