Most of them work at line frequencies only (50-60 hz). The Craftsman one apparently works on DC too, which could be very handy for checking alternators. But if the scale is 0-200 amps don't expect to do much else with it.Speaker impedance does change with frequency, but for all practical purposes the nominal impedance spec is close enough for power calculations. Anything beyond a ballpark measurement needs a non-inductive dummy load.</blockquote>
