1. A continuous analyte measurement system, comprising:

  • a memory;

    a base unit configured for mounting on a skin surface;

    an analyte sensor comprising a proximal portion configured for positioning within the base unit and a distal portion configured for insertion through the skin surface, wherein the analyte sensor is configured to generate one or more signals related to an analyte level; and

    a conductive member positionable within the base unit and in electrical contact with the analyte sensor;

    wherein the continuous analyte measurement system is configured to determine the analyte level using at least a drift correction factor associated with the analyte sensor, the drift correction factor determined by an algorithm of the continuous analyte measurement system using a drift profile; and

    wherein the drift profile is programmed into the memory of the continuous analyte measurement system prior to insertion of the distal portion of the sensor through the skin surface.
