Abstract:
1. A method for controlling a photometric measuring unit of a measuring device for examining a human or animal bodily fluid sample obtained by way of lancing, wherein: a test field partially wetted by a bodily fluid sample is illuminated and light from a measuring area that covers a portion of the test field is fed to a detector of the measuring unit; the measuring area is displaced relative to the test field toward a partial surface wetted by the bodily fluid sample and past the partial surface; during the displacement, the intensity of a detector signal is measured and an extreme value in the course of the detector signal is determined; the measuring area is returned to a position in which the extreme value of the detector signal was previously measured; and the position of the measuring area in which the extreme value of the detector signal was measured is used for a photometric determination of analyte concentration.
