- the AD count value should be about "100”
- the AD count value should be "1”.
- the approximation should be made to about "40000” and polynomial approximation would be performed. This means that the pressure sensitivity was adjusted at a constant temperature.
- the offset and the span are pressure sensors using piezoresistors, they have the temperature characteristics shown in FIG. Therefore, it is necessary to compensate for the pressure accompanying the temperature change.
- This pressure-temperature compensation first adjusts the pressure sensitivity under the above-mentioned constant temperature, for example, the lowest temperature, and then, under different temperature environments, the AD count corresponding to the highest pressure in the measurement range is measured in the lowest temperature environment.

As shown in Fig. 9, a constant current is applied from the constant current source 21 to the bridge, and the voltage change between the connection points PT1 and PT4 measured by the voltmeter 23 is converted to temperature. However, the bridge resistors have individual variations, so it is necessary to adjust the temperature sensitivity. The pressure is obtained by converting the voltage change between the connection points PT 2 and PT 3 measured by the voltmeter 22 into pressure.
- the temperature sensitivity adjustment is performed by gradually increasing the current of the constant current source 21 under the lowest temperature until a desired AD force is obtained, and obtaining an AD count at each temperature after the current adjustment.

- the pressure sensor 1 of the watch placed in the constant temperature and pressure chamber main body 1 1 can detect the pressure instantaneously.
- the temperature cycle and the pressure cycle shown in FIG. 12 are set and controlled. This setting control is performed by the constant temperature and constant pressure control unit 12. In other words, the pressure is changed at each temperature so that the cycle has a small temperature change. In Fig.12, four points of pressure and three points of temperature are selected. However, if there are many measurement points, more accurate compensation data can be generated.

That is, when the pressure sensor 11 detects a change in pressure from “ ⁇ 1 ”to“ ⁇ 4 ”(step S303), the calibration control unit 5 writes the temperature data into the memory (step S304), and sets the pressure“ ⁇ 4 Is written to the memory (step S305). Thereafter, a change from the pressure “$ 4” to “$ 3” is waited for (step S306), and if there is a change, the data of the pressure “$ 3” is written to the memory (step S307).
- the controller waits for a change from the pressure “ ⁇ 3” to “ ⁇ 2” (step S308), and if there is a change, writes the data of the pressure “ ⁇ 2” to the memory (step S309). Furthermore, wait for the pressure to change from “ ⁇ 2” to “ ⁇ 1” (step S 31 0) If there is a change, the data of the pressure "P1" is written to the memory (step S311). Thereafter, it is determined whether or not the processing at the highest temperature, that is, the last temperature “T3” ° C, has been completed based on the sensor output of the pressure sensor 1 (step S312). In (Step S312, NO), the temperature is sequentially changed from “T1” to “T2” ⁇ “T3” ° C. (Step S313), and the process proceeds to Step S303. On the other hand, when the process at the last temperature “T3” has been completed (step S312, YES), this process is completed. That is, the calibration processing ends.
- the constant temperature / constant pressure control unit 12 determines whether or not the set control for the temperature “T3” has been completed in step S212, and if not completed (step S212, NO), Is sequentially changed to “T1” ⁇ “ ⁇ 2” ⁇ “ ⁇ 3” (step S213), and the process proceeds to step S203 to perform the pressure change at the set temperature.
- step S212, NO the setting control for the temperature “T3”: is completed (step S212, YES)

As a result, a process synchronized with the setting control in the constant temperature and constant pressure control unit 12 is performed.
