Since the effect of sag is to make the measured length too Hello, you calculate it from the average moving range. This article addresses a way to combat accidental errors, which are usually Gaussian. Thus, the 0.01 digit is not meaningful. 1. Understanding that Probable Errors add in quadrature, the Probable Error in a length of time between two such measurements would then be:-+/- Squrt (0.52 + 0.52) = +/- 0.707 or +/- Squrt (0.252 +0.252 ) = +/- 0.35or +/- Squrt (0.342 +0.342 ) = +/- 0.48 ? The measurement increment of 0.1 may be too small in this case as it is just about equal to the smallest effective measurement increment.
