Most modern DVMs will do that, as long as you take care not to exceed the maximum input ratings of the DVM. A tru RMS DVM is best, because the ripple is not a pure sine wave, but average reading DVMs will give you an idea. >When you do measure, measure directly across the filter capacitor, you >can pick up some inaccurate measurements if you just "clip to the >chassis" far away from the cap.
