Select Home tab > Document panel > Attach to control the connection between the active document and the measuring device:
When you attach a document to a measuring device, PowerInspect compares the probe database of the document with the probe database of the device. If the probe heads are the same in both databases, the document's Machine tab is updated to show the tool on the device. If the probe heads are different, a warning message is displayed: click Yes to change the head specified in the document's probe database to match the head in the device's probe database; click No to change the device's probe database to match the head specified in the document.
