Abstract
There is disclosed a method for controlling a photometric measuring unit of a measuring device for a bodily fluid sample, 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 of the measuring unit is fed to a detector of the measuring unit, and the measuring area is displaced relative to the test field toward a partial surface wetted by the fluid sample and past the partial surface. The intensity of a detector signal is detected during the displacement, an extreme value in the course of the detector signal is determined, the measuring area is brought back to the position in which an extreme detector signal was previously measured, and the position of the measuring area in which the detector signal is extreme is used for a photometric determination of concentration.
