This document discusses sensor accuracy and precision. It defines three "laws" related to sensors: 1) nothing is true, 2) everything is permitted, and 3) there is nothing either good or bad but thinking makes it so. It then discusses the differences between sensor accuracy, precision, resolution, and another unspecified term. Accuracy is defined as how close a measurement is to the true value, while precision refers to the reproducibility or agreement of repeated measurements. Resolution is the smallest difference a sensor can detect. The document cautions that a manufacturer's specified accuracy may only be achieved under ideal test conditions and could vary in actual use. It encourages using tools properly and doing the right thing.

Q.The manufacturer's spec sheet says it is accurate to 0.00000001%
A.And it probably is - when measured in their QA test fixture using
their test procedures and according to their definition of 'accuracy'.
