Steve:
In order to upload sensor data and pint out a report, each sensor must have the following things manually entered by the user: location, (this is the specific error here), hole depth, and slab thickness. Once you go back and enter this information for each sensor, via the Datamaster unit, the information should upload no problem. If you have any additional issues, give up a call.
