In early 2023 we built some Rotary Motion Sensor (RMV-BTD) with a defect that caused them to not record motion on LabPro. The units work fine on LabQuests. Note on LabPro the Rotary Motion Sensor needs to be setup manually (See: Rotary Motion Sensor will not Auto ID with LabPro. ) regardless of if the unit is defective or not, but once the unit is setup, the readings should be non-zero if you move the wheel.
If you received one of these units, contact us to arrange a repair.
