1. A biosensing meter for receiving a sample strip that includes a sample well with an analyte reactant therein, said biosensing meter comprising:

  • sense means for outputting signals indicative of manifestations of a reaction in said sample well between an analyte-containing fluid and said analyte reactant;

    pluggable memory key means for insertion into an electrical receptacle in said meter, said pluggable memory key means including a plurality of stored parameter values and procedure routine specifications that are employed in controlling execution of an algorithm performed by said meter that enables determination of an analyte concentration value, said procedure routine specifications including stored values from which time values can be determined for controlling said sense means during execution of said algorithm; and

    processor means coupled to said memory key means and responsive to parameter values and procedure routine specifications accessed from said pluggable memory key means, for controlling operation of said sense means in accordance with said algorithm and for calculating from signal outputs from said sense means a concentration value of an analyte in said analyte-containing fluid in said sample well.
