This actually places limits on the resolution of your measurement system and the PE can be used to help determine the measurement increment. If the measurement increment is too large, you will need to decrease the measurement increment so it is within the range. Lets look at another example. A classical example is the change in length of a tape as the Cs/ = Sag correction per tape length. A precise measurement is one that is free of accidental errors.
