Calculations are performed for a sample under a few different circumstances: the sample is edited and saved, an analysis is added to the sample, the associated control sample is edited. Depending on how many associations exist, saving a sample may take a few seconds in order to facilitate all those changes.
Associated Equipment
If the test has an equipment type associated with it, the analysis will require that an equipment be selected. The value of the analysis will then be the factor of that equipment's most recent calibration.
