1. A method of manufacture for a non-invasive sensor comprising:

  • communicatively coupling a sensor to a test device, wherein the sensor is configured to emit and detect electromagnetic radiation;

    determining a first signal value for each wavelength of light emitted from an emitter of the sensor;

    storing the first signal value in a memory;

    placing the sensor on false tissue, the false tissue being opaque;

    operating the sensor to determine a second signal value for each wavelength emitted from the emitter of the sensor; and

    storing the second signal value in the memory.
