Abstract: Analyte monitoring device calibration is described. A calibration system generates calibration results for multiple analyte monitoring devices during a calibration evaluation process. To do so, the calibration system implements a calibration board that includes a single ground electrode shared by, but not physically connected to, the multiple analyte monitoring devices. An input voltage is applied to an analyte-sensing element of each of the multiple analyte monitoring devices. Analyte-sensing elements and the common ground electrode are placed into/in contact with a reference bath that includes a known concentration of an analyte to be measured. The input voltage causes each analyte-sensing element to generate an electrical current that is indicative of the reference bath analyte concentration. The calibration system includes a current meter that monitors the electrical current generated by each of the multiple analyte monitoring devices, which is interpreted by the calibration system to generate the calibration results.
