a (—): The flow components outside the scaled measuring range cannot be taken
into account for signal output.
A fault message is generated (# 351...354, current range) and the current output
responds in accordance with the parameter settings in the function FAILSAFE
MODE (4006).
b (- -): The current output signal is proportional to the measured variable assigned.
I [mA]
Use this function to enter a time constant defining how the current output signal reacts
to severely fluctuating measured variables, either very quickly (enter a low time
constant) or with damping (enter a high time constant).
