There is provided a determination apparatus. The determination apparatus includes (a) a determination device having a plurality of determination terminals, (b) a controller for selecting at least one of the plurality of determination terminals, determining a calibration reference standard, and setting of a property value of the determined calibration reference standard, and (c) a memory for storing a parameter of the determined calibration reference standard and a determined value for the parameter as determined by the determination device. The determination device determines an error of the determined value of the parameter, the error being stored in the memory, the determination device outputting the determined value after removing an effect of the error therefrom, and obtaining and storing a re-determined value for the parameter while maintaining the determined value of the parameter of the calibration reference standard in the memory.
