Randy — not sure why you feel the need for shielded wire for DC measurements, especially if you turn the LP filter on, unless you live under a transmitter. I use twisted pair 22 ga. solid copper bell wire for voltage measurments with no difficulties, and the thermals reduce very quickly. Silver plated copper would be even better I suppose. Heavy gauge wire is only needed for current measurements, which I seldom do. Dick Moore

Dick it is all in trying to get the last little bit of accuracy out of the meter. 1000 NPLC and or math stat would do better than messing with the leads... All this gets into the law of diminishing returns. 1 ohm test lead in series with a 10Meg input resistance that only come into play on the 2 upper ranges will induce an error of 0.1 ppm.

Heavy gauge wire has different thermal behaviour than think wire (area deepends on radius squared, surface only on radius) It is not always obvious which behaviour is preferable. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk@FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.
