Abstract
A method for distinguishing between types of electrochemical test sensors in a meter is disclosed. The method comprises the acts of providing an electrochemical test sensor comprising an enzyme and a chemical additive, contacting the test sensor to the meter to form an electrical connection, applying a potential having a magnitude sufficient to initiate a redox reaction of the chemical additive, and determining which type of electrochemical test sensor is being used based on whether a predetermined signal has been generated after the potential has been applied. The meter is adapted to determine an analyte concentration in a fluid sample.
