Calibration and testing

Device calibration

The metadata provides a generic class for storing Calibration metadata. In a generic calibration there is some set of known inputs and a paired set of measured output values.

Common calibrations include measuring power output (e.g. for lasers) with PowerCalibration and measuring volume outputs (e.g. for lick spouts controlled by a solenoid) with VolumeCalibration, but you can define any generic calibration using the base class.

Calibrations have an option to include fit parameters, if your calibration fit is not available in the FitType options please request that we add it by opening an issue.

Instrument testing

When collecting a test data asset on an instrument using a “calibration object” instead of a subject or specimen, you should set subject_id = "calibration" in all metadata files. Please also use the CalibrationObject in the Subject.subject_details to track information about the physical object used during calibration.
