tripper1000: I really don't understand why Auto-power-off is a desirable feature. It is something people seem to repeat without giving a moments though to. It is usually a false economy feature, both time and money wise. As mentioned, most are dumb, turning off regardless of what is going on, cause repeated interruption to work, 2nd, DMM's just don't use enough power to warrant it - the batteries last forever, often leaking before they go flat negating/eclipsing any battery replacement savings), 3rd DMM's are often used to monitor circuits (battery charging progress, erratic/intermittent faults etc) and auto-power off is a PITA in these cases.
