Title:
METHOD FOR MANUFACTURING PHYSICAL QUANTITY DETECTING APPARATUS
Document Type and Number:
Japanese Patent JP2004239676
Kind Code:
A
Abstract:
To easily detect erroneous assembly of pressure sensors having different sensitivities.
When the offset voltage of a pressure sensor having sensitivity A is adjusted, an offset voltage Va is adjusted within a specification range provided for the sensitivity A. When the offset voltage of a pressure sensor having sensitivity B is adjusted, an offset voltage Vb of the sensitivity B is adjusted outside the specification range provided for the sensitivity A. Therefore, by measuring an offset voltage of a sensor output signal, it is possible to easily detect error assembly of the pressure sensor without having to impress a prescribed pressure on a sensing part.
