Description of the Related Art As a conventional biosensor measuring device, a very small amount of body fluid such as blood is collected from a human body into a disposable sensor chip, and a current value generated by a reaction with a specific reagent carried on the sensor chip is measured. Is read by a measuring device to which a sensor chip is connected, and the values of blood sugar, cholesterol, lactic acid, and the like are measured. Such a disposable sensor chip is composed of a casing for collecting body fluid, an electrode and a reagent, but portions other than the reagent carried on the sensor chip can be shared. Also, in the measuring instrument, the hardware can be used in common if the calculation formula for converting the detected current value into a value corresponding to each concentration is changed. However, in the case of common use, for example, when a sensor chip for measuring blood glucose is connected to a measuring device for measuring cholesterol, there is a problem that a normal measuring operation cannot be performed. In addition, by changing the shape of the connecting portion of the measuring device, erroneous connection between different types of sensor chips and the measuring device has been prevented. Also, in the manufacturing process of forming the reagent on the sensor chip, it is inevitable that the performance of each lot varies, so the measuring instrument corrects this variation in the manufacturing for the actually detected current value. It is necessary to display blood sugar level, cholesterol level and the like. For this reason, conventionally, a calibration curve correction formula for compensating for variations in the output values of the sensor chip has been set in the measuring instrument, and a switch for calibration curve correction formula switching is attached to each sensor chip. I was letting it. Prior to the measurement, the user sets the switching chip in the measuring instrument, sets the calibration curve correction formula suitable for the sensor chip, and performs the measurement.

Since the shape of the connecting portion of the measuring instrument was changed, the production equipment including the mold had to be changed for each purpose, and the cost was high, so that the common use was not sufficiently achieved.
In addition, the calibration curve correction must be set by the user using the switching chip, and it is difficult and troublesome for visually impaired people, the elderly, and children. If the user forgets to change the setting, there is a problem that an accurate value is not displayed.
