YES!! That little $3 DMM ...is simply marvelous!! Ive bought at
least
20 of them over the years, give them out to people who want to
borrow
one of my decent Flukes or others, keep one in every vehicle etc
etc.


Those $3 meters have a gain adjustment pot inside. If you have a more
accurate meter and a stable low-noise voltage source (a battery) you
can set then to within one digit. Before adjusting them mine were off
as much as 50mV at 12.8V.
