First you shoud have to understand the basics of Analog & Analog to digital conversion techniques.
Analog meter's moving coil has deflected by Potential with certain level of current ( micro amp llevel,due to friction on pivot ) to show result in volt while digital meter is static device & no friction on measurment & digital meter can read potential with pico amp level drive current to measure volt.
The basic diffrence is drive current for deflection.
