1. A method for calibrating a noninvasive physiological sensor, the method comprising:

  • providing a blood model container for holding a blood model with known properties, blood model container including;

    at least one recess disposed on a surface of the blood model container, the at least one recess configured to move past a non-invasive sensor;

    a first portion of the at least one recess holding a first amount of the blood model; and

    a second portion of the at least one recess holding a second amount of the blood model, wherein the second amount of the blood model held in the second portion is greater than the first amount of the blood model held in the first portion;

    receiving a parameter measurement from the non-invasive sensor based on the blood model; and

    generating calibration data by comparing the parameter measurement with the known properties of the blood model.
