At initialization, each RPP moves (in the up position) to the RRV cuvette, then stops above the wash ports. The pumps stop when the reaction probes are positioned over the RRV cuvettes.
Each reagent cycle consists of these steps:
The reagent probes move to the aspiration position of the reagent trays and aspirate the reagent.
The probes move back to the wash ports, where deionized water washes their outside surfaces.
The probes move to the RRV and dispenses reagent into a cuvette.
The probes return to the wash ports, where deionized water washes the insides and outsides of the probes.
The reagent probes are now ready for another cycle.
If an assay is not running, you can operate the unit manually from the Manual Operation window.
