Method for distinguishing electrochemical sensors
First Claim
1. A method for distinguishing between types of electrochemical test sensors in a meter, the method comprising 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, the meter being adapted to determine an analyte concentration in a fluid sample;
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.
