If you have a matched amp with velocity input or similar, sure! If you have nothing, it seems really hard to get it turning a steady speed to test.

I've scoped tachometers that way. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
