for the PT 100
Position 1 and 2 on the operating mode switch have no function.
If you set the switch to "no linearization" and "no temperature compensation", module 464-8MF21
functions just like module 464-8MF11.
The characteristic linearization is possible for the following temperature ranges.
PT 100: -100° C to+850° C (-148° F to 1569° F)
