The HasReferenceMeasurementInstrument is a concrete ReferenceType and can be used directly. It is a subtype of NonHierarchicalReferences.

The semantic of this ReferenceType is to link a Node using a reference measurement instrument to such an instrument, like for example a calibration target using a reference measurement instrument.

The SourceNode of References of this type can be any Node using a reference measurement instrument, like for example instances of DynamicCalibrationTargetCategoryType.

The TargetNode of this ReferenceType can be any Node representing a measurement instrument.

The HasReferenceMeasurementInstrument is formally defined in Table 45.
