Appendix 1

Accuracy

This section describes the accuracy of a temperature input module.

Accuracy of the thermocouple input module

The accuracy (

) is calculated from the following formula.

Note that the operating ambient temperature change indicates the extent to which the operating ambient temperature is out of 
the range of 25

Ex.

Accuracy when B thermocouple is used, the operating ambient temperature is 35
