Abstract

An auto-calibration label for use with one or more sensing instruments. The label includes first and second encoded calibration information. The second encoded calibration information may correspond to a different instrument than the first encoded calibration information. The second encoded information may also be used to provide additional calibration information for use with the first instrument. The label may be removably attached to a sensor package including a plurality of sensors. A first conductive ink pattern is disposed on the label to define the first encoded calibration information. The first conductive ink pattern is disposed contemporaneously with or without a portion of a second conductive ink pattern defining the second encoded calibration information. An insulating layer is disposed on the first pattern. The second ink pattern is disposed on the insulating layer. The first pattern is operable with the first instrument, not the second instrument. The second pattern is operable with the second instrument, not the first instrument.
