Resolution vs. Accuracy

Resolution vs. Accuracy

watch2 caliperIn the Digital world that we live in , its easy to make the assumption that a precision measuring devices’ resolution is the same as it’s accuracy

It seldom is, and a good way to remember is this,

a watch reads to a second, but its not accurate to a second“, might be several seconds or even a minute off a month

True “accuracy” can only be assessed by comparison to traceable standards
