| 摘要 | An analog signal is supplied to a first conversion section of a physical quantity sensor device, converted to digital, and set to be an initial output value of the first conversion section. Adjustment information for the first conversion section is calculated based on the error between the initial output value and a target output value of the first conversion section. Before an initial output value of a physical quantity sensor is measured for calculating initial setting information of a physical quantity sensor device, the first conversion section is adjusted based on the adjustment information. Also, a digital signal is supplied to a second conversion section of the physical quantity sensor device, converted to analog, and set to be an initial output value of the second conversion section. The second conversion section is adjusted based on adjustment information for the second conversion section. | ||||||
