Abstract
A pressure change measuring unit causes a temperature control unit to operate and vary the temperature of a sensor chip in a predetermined temperature range, and measures changes in pressure value output from the sensor chip whose temperature is being varied. A temperature characteristic calculating unit calculates a temperature characteristic of the sensor chip from changes in the temperature of the sensor chip caused by the operation of the temperature control unit and changes in pressure value measured by the pressure change measuring unit.
