| 摘要 | A method for correcting an offset for a pressure difference measured using a differential pressure sensor situated in an air duct. The offset is computed using an output signal of a pressure sensor, including: transferring the air duct into a predetermined operating situation in which a predetermined pressure difference is considered to be applied to the differential pressure sensor, measuring a level of the output signal in the predetermined operating situation, and computing the offset based on the measured level of the output signal. | ||
