Patent ID: 7071712

Claim:
A method comprising the steps: producing a plurality of sensors wherein each sensor has an actual sensitivity; comparing the actual sensitivity of each sensor to a desired sensitivity to determine any deviation from the desired sensitivity; forming (x) groups of sensors each having sensitivities within a predetermined range of a desired sensitivity wherein (X) is ≧1; forming a group of resistors having different specific resistance values within a predetermined range for each group of sensors; connecting the group of resistors of specific resistance values to each group of sensors having a sensitivity within a predetermined range wherein the resistance values of the resistors are selected to identify the actual sensitivity of the sensors to which the resistors are connected within the group; and connecting at least one of the sensors with resistor to a detector means wherein the detector means measures the resistance of the resistor and determines the sensitivity of the sensor from the measured resistance for setting the operating measuring ranges of a manufacturing device based on the sensor sensitivity.
