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 (in steps of 0,5 _C).
