# Parameter (GRR)

The Part can be mapped to a specific Parameter for a local Machine only if, it has not been mapped to that Parameter earlier or if all the trials for that specific Part and Parameter are completed. If a Part has been mapped to a Parameter, with some Reading Mode for a machine, then the same Part cannot be mapped to the same Parameter with another Reading Mode for the same machine, until all the Trials for that Parameter have been completed. Maximum 16 Parameters can be mapped to a Part on a local Machine.

If the reading mode is Manual Entry or Single Instrument, then the Parameter Code drop down list box displays only the parameters that have been defined in the Part Parameter master and have not been mapped to the selected Part on the local machine.

If the reading mode is Fixture, then the Parameter Code drop down list box displays only parameters that have been defined for the selected Fixture in the Fixture Settings screen and have not been mapped to the selected Part on the local machine.
