Being able to perform both 2-wire and if practical 4-wire resistance measurements on these assemblies. </FONT></DIV><DIV><FONT size=2>  2. Being able to measure pin-to-pin continuity resistance down to about .5 ohms.</FONT></DIV><DIV><FONT size=2>  3. Being able to measure resistors to within .1%.   </FONT></DIV><DIV><FONT size=2>  4. Being able to measure leakage resistance between any conductor and any other conductor, with a threshold as "greater than 80 megaohms.</FONT></DIV><DIV> </DIV><DIV><FONT size=2>I am seeking any guidance, tips, suggestions and direction to accomplish any part or all of such a cable Assembly test system.</FONT></DIV><DIV> </DIV><DIV><FONT size=2>I have the following equipment and software, and would like to be able to use it in this application, but am open to all suggestions:</FONT></DIV><DIV><FONT size=2>  a.
