Document Type and Number:
WIPO Patent Application WO/2010/137168
Kind Code:
A1
Abstract:
At the use site of an A/D conversion unit (11), an ADC code (Cd) at the time when an analog input value (Sa) is inputted to an A/D conversion circuit (12) is measured to attain a user's measured value (uP1). A user's set value calculating unit (15) calculates a user's offset value (Uo) and a user's gain value (Ug) on the basis of the user's measured value (uP1) of one point, a factory offset value (Fo) and a factory gain value (Fg), and storing the calculated user's offset value (Uo) and the user's gain value (Ug) in a nonvolatile memory (14).
