The DynamicCalibrationTargetCategoryType characterizes a calibration target that is created by using a high precision measurement instrument, to determine the measures of an item to use it later on to calibrate lower precision equipment with it. This Item can be a piece created during the normal production process or an item specifically created for calibration purposes. Such targets are usually short lived as they are not made from special wear resistant materials, which distinguishes them from the ReusableCalibrationTargetCategoryType. The calibration target represents an individual piece or item, that is, if a new piece should be used or item is created, a new Object of this ObjectType shall be created. The ObjectType is formally defined in Table 54.

Attribute Value        
BrowseName DynamicCalibrationTargetCategoryType        
IsAbstract False        
Description Characterizes a calibration target to be used together with a measurement instrument, that determines the values to be calibrated. It can be a piece created during the normal production process or an item specifically created for calibration purposes. The calibration target represents an individual piece or item, that is, if a new piece should be used or item is created, a new Object of this ObjectType is created.

Subtype of the BaseCalibrationTargetCategoryType defined in 7.4.2, i.e. inheriting the InstanceDeclarations of that Node.          
           

This ObjectType does not define any InstanceDeclarations.

Objects of this ObjectType should use References of the ReferenceType HasReferenceMeasurementInstrument defined in 7.6.1, or a subtype of it, to relate the calibration target to the measurement instrument used to determine its features.

In case the piece or item used as calibration target is also managed otherwise by the OPC UA Server, Objects of this ObjectType may reference the other representation to make the relationship explicit.
