4 - Description of Function
Positive Identification (PosID)
The figure shows how horizontal barcodes (e.g. on microplates) are scanned.
“No Tube”
Sensor
The “No Tube” sensor checks if a carrier is actually transported when the gripper
moves. Furthermore, it monitors the presence of the tubes in the rack. This is
necessary, because the barcode scanner cannot distinguish between a tube with
missing or incorrectly positioned barcode and a missing tube.
