Abstract: The present invention provides an Analyzer adapted to receive an immunoassay cartridge comprising an imaging module including a two-dimensional light sensor and a plurality of light sources. The light sources and the two-dimensional light sensor are arranged such that the light sources are adapted to illuminate a result display section and a graphical code of the immunoassay cartridge and the two-dimensional light sensor is adapted to acquire images of both the graphical code and the result display section. The analyzer comprises an oscillator portion being adapted to cause the immunoassay cartridge to perform oscillations at a pre-set oscillation frequency. The analyzer comprises a processing section adapted to process an image of the graphical code acquired by the two-dimensional sensor to determine the pre-set oscillation frequency. The analyzer comprises a controller adapted to control the oscillator portion to cause the immunoassay cartridge to oscillate at the pre-set oscillation frequency.
