Initialization: The tray rotates clockwise until DTT cuvette 1 is in the aspiration position.
During assay, the DTT rotates clockwise or counterclockwise, depending on which rotation is smaller. For each sample, it performs these actions in a 3 second cycle:
Moves cuvette to mixer position (after sample is dispensed into DTT cuvette).
Moves cuvette to aspiration position (after sample is mixed).
Samples remain in cuvettes until all samples have been processed and analysis data has been collected. This allows for reassay.
Moves cuvette to dispense position (after assay is complete and cuvette is washed).
Exception: If a sample requires special purpose diluent, the DTT cuvette remains at the dispense position for two dispense cycles (by the DPP):
The cycle repeats until all samples are processed. During each cycle, unused cuvettes are washed.
If an assay is not running, you can operate the unit manually from the Manual Operation window.
