A CARTRIDGE FOR BODY FLUID MEASURING STRIPS AND A METHOD FOR INCLUDING A CALIBRATION CODE TO THE CARTRIDGE AS WELL AS A METHOD FOR RECOGNIZING THE CODE

摘要

A cartridge (2) for storing a plurality of test strips (32) suitable for analyzing body fluid, such as blood is designed such that the test strips (32) can be brought out of the cartridge (2) for performing a body fluid measurement. Such test strips (32) need to be identified in order to calibrate the measurement to lot- to- lot variations of test strips. The identification is accomplished by measuring the resistance of a resistor (9) attached to tne cartridge (2). The measurement of the resistance is carried out through a direct sensor - to - controller circuit using the RC timing method.
