*1: Type B dose not carry out temperature compensation and can not measure under 44 °C

*2: Wiring resistance for the signal cables of IN A and IN C must be identical. Yokogawa RTD Input Module AAR181-S50

*3: In dual redundant configuration, this effect is ±40 μV.

*4: This accuracy changes due to the installation condition.

If measured temperature is lower than 0 °C, multiply the above value by the following coefficient (K):
