Calibration Records

Calibration records store information about the calibration event that you have performed either manually or using a device. Based on the type of calibration that you have performed, the following Calibration records are created:

The following table provides an alphabetical list and description of the fields that exist for the aforementioned Calibration families. The information in this table reflects the baseline state and behavior of these fields. This list is not comprehensive.

Field Data Type Description Behavior and Usage
