Abstract
A calibration process utilizes two nearly identical sensors. The characteristic output curve of the first sensor is obtained using the measuring outputs of the second sensor. In particular, the first sensor has a characteristic output curve f[x] where x is a physical variable to be measured. The second sensor has an output curve y[x].apprxeq.f[x+a]. Starting from an initially known portion of the curve f[x], outputs of the second sensor are utilized to extend the known portion of the characteristic output curve f[x] of the first sensor into ranges of the variable x where this function is not yet known.
