TIME CONSTANT Use this function to enter a time constant defining how the current output signal reacts to
(4005) severely fluctuating measured variables, either very quickly (enter a low time constant) or
with damping (enter a high time constant).

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.
mA
This option is not available under these circumstances, because the 0_4 mA value and
the 20 mA value have different signs.
Flow components outside the measuring range are buffered, balanced and output after
a maximum delay of 60 seconds.
