Abstract
The method of operation of a meter includes placing a sample on a test strip, assigning a first electrode of the test strip to be a counter electrode, applying a first signal to the test strip during a first period of time, assigning a second electrode of the test strip to be the counter electrode, applying a second signal to the test strip to measure the concentration of an analyte in the sample.
Claims20
A method of operation of a meter to measure a response of a sample on a reaction chamber of a test strip, comprising:
- assigning a first electrode of the test strip to be a counter electrode;
- applying a first signal to a working electrode of the test strip during a first period of time;
- assigning a second electrode of the test strip to be the counter electrode;
- applying a second signal to the working electrode of the test strip during a second period of time;
- and
- measuring the response during the second period of time.
