A good DMM usually offers 4.4 digit accuracy:    0.000 to 1.999     That is 1 part in 2000 or 0.05%


An inexpensive digital scope typically has 8-bits of vertical resolution:   That is 1 part in 256.


A human has to read the scope by eye.  I think it is difficult to get better than 1 or 2% accuracy that way.

>> 4.4 digit accuracy

     That should be "four and one half digit accuracy

d-glitch has it right.
Of course the dmm may have calibration problems so the accuracy may not be as good as the precision but even a cheap dmm will read voltages better than a good scope.

Measuring a specific voltage level? Or measuring (and displaying) changes in voltage?
