Abstract

This invention relates to bio sensing meters for determining the presence of an analyte in a biological sample, and, more particularly, to a bio sensing meter whose operation is controlled by a code provided by a removably pluggable coding module. The invention further relates to a coding module pluggable into a bio sensing meter for receiving a sample strip. The coding module defines at least one code, said code ciphering at least one parameter value that is employed in controlling the operation of said meter, for example by controlling the execution of an algorithm performed by the meter that enables determination of an analyte concentration value. The at least one code is represented by at least one electrical component having a determined characteristic, preferably a resistance.
