Abstract
The invention concerns an analyte measuring system comprising a test tape (22) having a plurality of functional elements (20) including a test field (46), a further comprising a meter (12) having a tape drive (24) operable to advance the test tape (22), a light source (30) adapted to illuminate at least one measuring spot at a measuring position, and a measuring engine (32) to receive optical signals from the at least one measuring spot for detection of the analyte in the body fluid. For tape positioning, it is proposed that the measuring engine (32) comprises a signal processor (34) operable to determine if a test field (46) is in the measuring position, said determination comprising an identification of a pre-determined distance between at least two functional elements (20) in the optical signals obtained while advancing the test tape (22).
