*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
