Abstract

An auto-calibration circuit or label (20) is formed to be used with an instrument (10). A structure is provided that includes an electrically conductive layer. A pattern is created with the electrically conductive layer using a laser to form an auto-calibration circuit or label. The pattern is adapted to be utilized by the instrument to auto-calibrate. The pattern may be adapted to be utilized for a first instrument and a second instrument to auto-calibrate in which the first and second instruments are different.
