After upgrading the LabPro with Logger Pro 3.1 or 3.2, if you start the DataMate application and do not use the [CLEAR] button on the Main Screen to refresh the setup, your motion detector may not collect good data. The motion detector will appear to be working on the Main Screen, emitting clicks and showing reasonable live readouts. However when you begin data collection the motion detector will not click and the “SAMPLING” message will appear indefinitely.

Here is a simple work around:

-Connect the calculator to the LabPro
-Start the DataMate program
-When the Main Screen appears, press the [CLEAR] button to clear the DataMate setup.
-Now connect your motion detector and allow it to auto-id or set it up manually.
