Abstract

In a method for calibrating a measuring device by using a case which includes a case main body configured to accommodate the measuring device, a restricting portion configured to restrict translation of the measuring device accommodated in the case main body and reference surfaces provided in the case main body to face the respective sensor electrodes, a plurality of detection values is acquired in a state where translation of the measuring device accommodated in the case is restricted by the restricting portion, the reference surfaces face respective sensor electrodes of the measuring device and a high frequency signal is applied to the sensor electrodes. Then, coefficients in functions used in calculating measurement values are calibrated such that the measurement values become a predetermined value.
