PC-DMIS uses probe compensation if this registry entry is set to 1 (TRUE).
Entry Name: ScanDialogPrbComp
Entry Type: Whole number that specifies TRUE (1) or FALSE (0). The default value is 1.
In most cases, you probably don't need to perform this compensation since a scan's FINDNOM operation automatically does it. However, if you don't have CAD and you want to reverse-engineer a part, you should select this check box.
