5.11 Zero Count Check (F50, only firmware v1.3 or higher)

The instrument is able to perform a so-called

Zero Count Check. This check is carried

out with

no cassette placed in the insertion slit of the instrument and with the lid

closed. The check comprises an enumeration of the number of CCD-pixels that shows
elevated signal levels. If this number of pixels is above a predefined limit then the
cassette insertion slit might be contaminated with an interfering particle, like a dust
particle. An error message is shown in the display and a cleaning of the insertion slit is
recommended (refer to section 7 Maintenance of NucleoCounter SP-100).

If a PC with SemenView is connected to the instrument a contaminant can often be
observed as an object, which is stationary in all images.

Zero Count Check type in “F50 + ↵
