A method of calibrating a monitoring device to generate calibrated vital sign data using a calibration device includes positioning the monitoring device in a first position on a patient, generating vital sign data with a sensing assembly of the positioned monitoring device, and processing the vital sign data with the calibration device to determine if the vital sign data is calibrated vital sign data or uncalibrated vital sign data. The method also includes generating a calibrated data signal if the vital sign data is calibrated vital sign data, generating a reposition signal if the vital sign data is uncalibrated vital sign data, and repositioning the monitoring device on the patient until the calibrated data signal is generated.
