"Dennis Monticelli" <[EMAIL PROTECTED]> made an utterance to the drakelist gang ---------------------------------------------------------------------- I have both an old Fluke handheld DVM and a Simpson 260 (for doing calibrations as people have noted). The 20k/volt input Z is kinda low by modern standards but many service manuals of the era call out voltage readings with 20K/volt loading. If you use a modern meter, you may read a higher number than should be compared with the nodal voltages.
