(Explanation of calibration method)
The calibration method of the activity meter 1 will be described with reference to FIG. 3A.
As shown in FIG. 3A, the activity meter 1 is installed in the homeothermic R. With the temperature Tr of the constant temperature chamber R set to 37 ° C. and the activity meter 1 and the air E in the constant temperature chamber R reaching thermal equilibrium, the first temperature data S3 and the second temperature sensor of the first temperature sensor 30 are reached.

（補正方法の説明）
次に、図３（ｂ）を用いて活動量計１の補正方法を説明する。当該補正は、周囲温度の影響で第１温度センサ３０に発生する誤差分を低減するためのものである。
(Explanation of correction method)
Next, a correction method for the activity meter 1 will be described with reference to FIG. 3 (b). The correction is for reducing an error amount generated in the first temperature sensor 30 due to the influence of the ambient temperature.
図３（ｂ）に示すように、活動量計１の身体接触面１１を恒温水槽Ｗの隔壁Ｂに当接するように設置する。次に、恒温室Ｒ内の温度Ｔｒを、例えば０℃〜４０℃の範囲において１０℃間隔で変化させる。そして、恒温室Ｒの温度Ｔｒを各温度に設定した状態で、恒温水槽Ｗの温度Ｔｗを３２℃〜４２℃の範囲で、例えば１℃間隔で変化させ、第２温度データＳ４と、第１温度データＳ３と恒温水槽Ｗの温度Ｔｗとの差である第１温度データ誤差分△Ｓ３とを、図１に示す記憶手段６３ｂに記憶する。なお、上記において第１温度データＳ３は温度データ校正値Ｔｈで校正された値とする。また温度の設定間隔は上記以外でも良いのは勿論である。 As shown in FIG. 3B, the body contact surface 11 of the activity meter 1 is installed so as to be in contact with the partition wall B of the constant temperature water tank W. Next, the temperature Tr in the homeothermic chamber R is changed at intervals of 10 ° C., for example, in the range of 0 ° C. to 40 ° C. Then, with the temperature Tr of the constant temperature chamber R set to each temperature, the temperature Tw of the constant temperature water tank W is changed in the range of 32 ° C. to 42 ° C., for example, at 1 ° C. intervals, and the second temperature data S4 and the first The first temperature data error amount ΔS3, which is the difference between the temperature data S3 and the temperature Tw of the constant temperature water tank W, is stored in the storage means 63b shown in FIG. In the above, the first temperature data S3 is a value calibrated by the temperature data calibration value Th. Needless to say, the temperature setting interval may be other than the above.
次に、相関式算出部６２は、記憶手段６３ｂに記憶した第２温度データＳ４と第１温度データ誤差分△Ｓ３との相関式を算出し、当該相関式を用いて第２温度データＳ４に対応する第１温度データ誤差分△Ｓ３を算出し、第１温度データＳ３を補正する。
図４を用いて詳述する。図４はデータ散布図であって、横軸は第２温度データＳ４であり、縦軸は第１温度データＳ３と恒温水槽Ｗの温度Ｔｗとの差である第１温度データ誤差分△Ｓ３である。
Next, the correlation formula calculation unit 62 calculates a correlation formula between the second temperature data S4 stored in the storage means 63b and the first temperature data error ΔS3, and uses the correlation formula to generate the second temperature data S4. The corresponding first temperature data error ΔS3 is calculated, and the first temperature data S3 is corrected.
It will be described in detail with reference to FIG. FIG. 4 is a data scatter plot, in which the horizontal axis is the second temperature data S4 and the vertical axis is the difference between the first temperature data S3 and the temperature Tw of the constant temperature water tank W, which is the first temperature data error ΔS3. is there.
図４に示すように、０〜４０℃の範囲で第２温度データＳ４が変化した場合、第１温度データ誤差分△Ｓ３は、本実施例では、α、βを定数とし、△Ｓ３＝αＳ４＋β、との相関式に表すことができるので、この相関式から、第２温度データＳ４の影響によって生じる第１温度データ誤差分△Ｓ３を算出し、第１温度データＳ３を補正することによって、第１温度データＳ３の精度を高めることができる。 As shown in FIG. 4, when the second temperature data S4 changes in the range of 0 to 40 ° C., the first temperature data error ΔS3 is set to α and β as constants in this embodiment, and ΔS3 = αS4 + β.
