1. A noninvasive medical monitoring device, said monitoring device comprising:

  • a physiological sensor configured to output at least one physiological signal; and

    a monitor comprising a display and a signal processing system comprising;

    a transmittance calculator configured to;

    calculate at least one reference transmittance value from said at least one physiological signal, wherein said at least one reference transmittance value is indicative of a reference position of said physiological sensor on a measurement site of a patient, andcalculate at least one operating transmittance value from said at least one physiological signal, wherein said at least one operating transmittance value is indicative of a position of said physiological sensor on said measurement site of said patient;

    a placement indication calculator configured to calculate a placement indication value based, at least in part, on said at least one reference transmittance value and said at least one operating transmittance value, wherein said placement indication value is indicative of said position of said physiological sensor on said measurement site relative to said reference position; and

    a processing module configured to determine whether said placement indication value exceeds a placement indication threshold.
