Abstract

An interim auto-calibration circuit or label adapted to be used with a sensor package. The sensor package is adapted to be used with first and second instruments to determine the analyte concentration of fluid sample. The instruments are different and include respective first and second plurality of pins that are in different patterns. The sensor package comprises a plurality of electrical connections that includes a plurality of contact areas. The contact areas have a first and second contact sections being shorted together. The first contact sections are adapted to contact a respective one of the first pins. The second contact sections are adapted to contact a respective one of the second pins. The electrical connections assist in conveying information corresponding to the test sensors. The information is adapted to be utilized by the first and the second instruments to auto-calibrate for the test sensors.
