    Looking through the E-books & wanting to build an ammeter for special function, with regard to a shunt, reference is made to "milli-ohms"........

    Is there any type of DMM on the market that will actually read with that degree of resolution ?? My Fluke 77 definitely won't do it.........

    I have several large pieces of compressed carbon, formerly vanes in a rotary vacuum pump, and a couple of other sources, suchas the positive post out of zinc-carbon batteries of various sizes, which should make excellent shunt material.

    Or am I better advised to use copper wire for shunts, a/w/a resistors, due to the math being there to work with ??

    Interesting link !!! :) Certainly will yield some new toys.........and oddly enough it is along the same line as the High amp jumper based on millivolt readings culled from a specific length of #8 copper wire...and attention to Ohms' law.....I got this while working for a Deere dealer, it just never clicked to go the same basic route to do the other

    Thanks again Jaguarjoe
