Engineers distinguish between accuracy, a measure of how close
a observed value is to the true value, and resolution, which
is a measure of the device's ability to resolve small changes.
Either specification is useful in its own right, and professional
instrumentation will always have both specs. So even if the
last digit or two of a measuring device are not accurate, they
may still be useful.

You may want to check audio ADCs and DACs for example, which
have atrocious accuracy, but excellent resolution. An example
of the opposite might be a voltage reference, which has excellent
accuracy, but no resolution at all.

Of course in general, there is a tendency of accurate instruments
to have a better resolution too.
