zation for the PT 100
Positions 1 and 2 on the operating mode switch have no function.
If you set the switch to "no linearization" and "no temperature compensa-
tion," module 464–8MF21 functions just like module 464–8MF11.
Characteristic linearization is possible for the following temperature ranges:
PT 100: – 100 C ... + 850 C
