Measuring devices each deliver a measuring value for a property of the measuring liquid. From certain measuring values there are formed auxiliary values. Each auxiliary value is compared with a threshold value in order to produce a recognition signal. The individual recognition signals are grouped together into a recognition-data word. Each preparatory state corresponds to a respective preparatory-data word. The calibrated state corresponds to a calibration-data word. The recognition-data word is compared with the other data words. Upon coincidence thereof, there is produced an appropriate control signal which is delivered to a computer, in order to trigger thereat a computation operation corresponding to the preparatory state or a calibration. For instance, in a diluted blood sample there are measured the erythrocyte concentration, the hemoglobin content and the conductivity and used as auxiliary values. Depending upon the results of the comparison of such auxiliary values with the related threshold values there is produced a control signal which triggers the corresponding computation of the erythrocyte concentration or the hemoglobin content in the blood sample or the calibration of such computation. The invention is preferably employed for hemotological analysis and more generally for the series analysis of liquids. |
