Abstract

A body fluid component analyzing system in which even if the lot of sensor chips is changed, parameters can be calibrated without changing memory keys. The system comprises a measurement instrument body having calculating means for calculating a characteristic of a component, a container containing a sensor chip for sensing a characteristic of at least one component of a body fluid, and a case in which the measurement instrument body and the container are set. The calculation parameter(s) of one or more sensor chips can be automatically transferred to the measurement instrument body by transfer means.
