In order to increase sensor manufacturing yield without compromising patient safety, at least one first value is determined respectively for at least one sensor feature parameter indicative of characteristics of a physiological sensor and the determined value(s) is/are stored in a predefined memory location prior to use of a physiological sensor. In response to the physiological sensor being connected to a patient monitor, at least one second value is defined respectively for the at least one sensor feature parameter and the at least one first value of each of the at least one sensor feature parameter is retrieved from the predefined memory location. Each of the at least one second value is compared with respective at least one first value and a decision is made, based on the comparison, on the acceptance of the physiological sensor.
