More Information
Summary:A hand-held test meter for use with an analytical test strip in the determination of an analyte (for example, glucose)in a bodily fluid sample(such as a whole blood sample)includes a housing, a display module with a display illumination sub-module, a micro-controller disposed in the housing and a display illumination adjustment circuit block. The display illumination adjustment circuit block has a photo-sensor configured to sense ambient light levels and output a photo-sensor signal, a photo-sensor amplifier configured to receive the photo-sensor signal and output an amplified photo-sensor signal, a transfer function sub-block, and an illumination sub-module driver. The illumination sub-module driver is configured to drive the display illumination sub- module to illuminate the display module based on an illumination sub-module driver input signal.
