S5-90U/S5-95U
Positions 1 and 2 on the operating mode switch have no function.
If you set the switch to "no linearization", module 464-8MF21 functions just like module 464-8MF11.
The characteristic linearization is possible for the following temperature ranges:
PT 100: -200° C (-328° F) to+850° C (1562° F)
