*1: Model AAT145 is also in compliance with JIS C1602:1981.
*2: Type B dose not carry out temperature compensation and can not measure under 44 _C.
*3: Model AAR145 is also in compliance with JIS C1604:1989 (Pt100, JPt100).
*4: Each wiring resistance should be equal.
*5: This accuracy changes due to the installation condition.
If measured temperature is lower than 0 _C, multiply the above value by the following coef?cient (K):
= Thermoelectromotive force per degree at 0 _C
