    Operating manual BMGZ 600A 2 Definitions Measuring uncertainty: Each measuring device has some inaccuracy, but however, inaccuracy is in a small, defined range of tolerance. This deviation of the measuring value referring to the effective value is called measuring uncertainty. Measuring accuracy: Its behaviour is the contrary to the measuring uncertainty: Increases the uncertainty, decreases the accuracy, and also in reverse mode.
