Recording only the event related data is very useful when analyzing data. A laser micrometer may be registering 400 scans or more a second. With this much data coming in, recording all of it simply isn't practical. It can be very hard just to find the set of measurement data where the problem occurred. Event Characterization is designed to save only the data of interest during a run.

An operator may have defined a diameter measurement for a product, and would like to know the maximum and minimum sizes of that product. For example, if the product has variations in size that do not exceed the specifications, then knowing the minimum and or maximum values of the product will help in perfecting the production process. If, for example the product was often thicker than it needed to be, even though it remained in spec, the process could be refined and the cost of the extra material can be eliminated.
