I guess by accurate I mean the digital readout to me is more precise.
The Weston and Norwood I had aged and the electrical contacts
deteriorated along with the accuracy of the meter readings. For me
digital offers a more "specific" reading than analog, but I guess this
is just my preference. Maybe I should try one of the small little
analog meters and see.
