Claim 19:
20. A non-transitory, computer-readable medium having instructions that, when executed by one or more processors, cause the one or more processors to perform a method for calibrating one or more sensor parameters of a glucose sensor used for measuring a level of glucose in a body of a user, the method comprising:
periodically measuring electrode current signal (Isig) values for a working electrode;
generating Electrochemical Impedance Spectroscopy (EIS) parameter values for the working electrode based on an EIS procedure;
measuring Vcntr values of counter voltage for the glucose sensor;
based on the Isig values, the EIS parameter values, the Vcntr values, and a plurality of sensor glucose (SG) predictive models, calculating a respective SG value for each of the SG predictive models;
applying a factory calibration factor to fuse the respective SG values to calculate a single, fused SG value;
performing error detection diagnostics on the single, fused SG value to determine whether a correctable error exists in the single, fused SG value;
in a case where the error detection diagnostics determine that a correctable error exists, correcting the correctable error to generate a corrected, single, fused SG value; and
providing the corrected, single, fused SG value.
