### Half Relocation

The Half Relocation check box lets you determine whether or not PC-DMIS performs a FULL RELOCATION (FULL LEAPFROG) operation (if not selected) or performs a PARTIAL RELOCATION (PARTIAL LEAPFROG) operation (if selected).

Relocation simply refers to moving the portable measuring machine to a new location.

- Doing a full relocation (clearing this check box) means you would need to measure something before you move the portable machine and then re-measure some or all of those items after moving the machine. Remeasuring allows PC-DMIS to determine the new location of the machine.

- A half relocation (selecting this check box) means you move the portable machine first and then measure the datum features.

Datums are only measured with the Measure Datums option, and the Half Relocation control is grayed out and inaccessible when the Measure Datums option is chosen.

The portable machine must be moved to the new position before executing a Measure Datums method Leapfrog because features are measured only once during the relocation. There is no option of an alternate procedure for this method.

I tested Half Relocation with the Measure Point Sets method. I performed a successful relocation via Point Sets, and tried to perform another by moving the machine to the new location before measuring the point sets. I selected Half Relocation and clicked Measure All. As suspected, I was not prompted to move the machine after measurement, but the results were completely unusable in excess of 200mm residual error in X. I could log a report of my results if I knew what to expect when Half Relocation is selected.
