Best Answer

a digital multimeter uses similar input circuits to those used in an analog multimeter for the various scales, but uses a dual slope integrating analog to digital converter to get a precise digital value of four or five digits to display. this type of analog to digital converter is slow but very precise, also though slow it is more than fast enough for a human to not perceive the slowness.
