Je größer also die verwendbare Matrix ist, desto weniger Abschneidungsartefakte treten auf. In diesem Bildbeispiel sind die Kantenoszillationen im Bild mit der Matrix 128 x 256 sichtbar, im Bild mit der Matrix 256 x 256 jedoch nicht vorhanden. Das Abschneidungsartefakt kann durch Anwenden eines Rohdatenfilters oder eines elliptischen Filters minimiert werden. Der Filter glättet die Kanten der endlichen Abtastung und reduziert dadurch die Auswirkungen des Abschneidungsartefakts. Beachten Sie in diesen Bildern, dass der starke Rohdatenfilter die Kantenoszillationen verringert. Er verringert jedoch auch die räumliche Auflösung. Aspirate Probe Errors: Obstructed probes Bent aspirate probes These errors can cause cuvettes to overflow at the wash station and erroneous results.   Replace Aspirate Probes Learn how to replace aspirate probes.   Select the play arrow to begin the video.  Note: After replacing an aspirate probe, verify the probe is operating correctly by performing the Dispense Wash Fluid & Aspirate test in Diagnostics.   When complete, select the X in the upper-right-hand corner to close the window and continue.
