These coefficients are used at compensation calculation below step (4) or step (5). This temperature data is used at step (4) using coefficients of step (1) for compensation. • Read pressure data which are output by absolute pressure sensor through I2C. This pressure data is used at step (5) using coefficients of step (1) for compensation. • Using coefficients of step (1) and temperature data of step (2), the operator corrects temperature data by using following temperature compensation formula.

Ta 25 [°C] Po = Pl + 90000 + (Pl + 90000) (ct0 + bt0 × Tr) - 90000 = Pl + 90000 + (Pl + 90000) (ct × 2-18 + bt × 2-31 × Tr) - 90000 Ta < 25 [°C] Po = Pl + 90000 + (Pl + 90000) (ct20 + bt20 × Tr) - 90000 = Pl + 90000 + (Pl + 90000) (ct2 × 2-18 + bt2 × 2-31 × Tr) - 90000 2SMPB-01-01 Note: Temperature calibration of the pressure is calculated after converting to absolute pressure value because Pl is a relative value from 90 [kPa]. 8 Po: Final compensated result.

Therefore power-on reset is not working properly on below situations. At the time of the following circumstances when power is switched on again: • The potential of the VDD pin is not 0 volt. • The instantaneous voltage drop occurs in the VDD pin.

(2) The product are not water proof. The product shall be kept dry in use including the sensor port. (3) The product shall not be used under dew-condensing conditions. Frozen fluid on sensor chips may cause fluctuation of sensor output and other troubles. (4) The product shall be used within rated pressure. Usage at pressure out of the range may cause breakage. (5) The product may be damaged by static electricity. Charged materials (e.g. a workbench and a floor) and workers should provide measures against static electricity, including ground connection. (6) Overpowering pins may deform terminals and detract solder abilities of sensor terminals. The product shall not be dropped and handled roughly. (7) The product shall not be used under dusty or damp condition. (8) Please connect the sensor terminals according to the connection diagram. (9) The product shall not be used under high-frequency vibration including ultrasonic wave. (10) This product uses the elastic adhesive for bonding the lid, so do not add excessive stress to the lid. (11) If you use other conditions described in this document, please check yourself in advance. Environmental conditions for transport and storage (1) The product shall not be kept with corrosive gases (e.g. organic solvents gases, sulfur dioxide and hydrogen sulfide gases). (2) The product are not water proof. The product shall be kept dry during storage. (3) By condition of the place and storage period, there are cases that strength of outer boxes may be degraded. Please use the product in order. (4) For this product, please keep away from direct sunlight or ultraviolet rays. (5) The product shall be kept in appropriate conditions of temperature and humidity. (6) Sometimes the color of terminals of the product may change depending on the conditions. It is not covered under warranty. (7) The product shall not be kept under dusty or damp condition. 2SMPB-01-01 Note: Specifications in this document are subject to change without notice. • Application examples provided in this document are for reference only.
