PURPOSE: An acceleration measuring apparatus is provided to calibrate its output with a zero-point in the state that no acceleration is applied as well as sensitivity. CONSTITUTION: An acceleration measuring apparatus(1) comprises a printed wiring board, an acceleration sensor(10), an amplifier(3) for amplifying an output of the acceleration sensor(10), an A/D converter(4) for converting an analog signal to a digital signal, a memory for storing a calibration parameter, a microprocessor(5) for performing a calibration calculation, and a temperature sensor(6) for measuring an ambient temperature. The microprocessor(5) includes a memory(5a). |
