When initialized, the mixers move to their mixer positions, then goes to the down position. If a mixer is already at the mixer position, it is raised, then lowered.
During each cycle of the RRV, the following steps occur:
NOTE
This sequence applies to each mixer; the mixers used depend on the analysis conditions.
The mixer moves up and over to the wash port, where it is washed with deionized water. During this period, the reaction tray mixer wash valve (MWEV1 or MWEV2) is open (depending on the mixer being washed), and (briefly) the mixer rod is on.
The mixer moves up and moves to the mixer position, where it lowers into the RRV cuvette.
The rod turns on to mix the sample and reagent.
The mixer moves up from the cuvette and moves back to the wash port.
The next cycle begins.
If an assay is not running, you can operate the unit manually from the Manual Operation window.
