2. Defined measuring range (m–n):m andn have the same sign
A0001272
3. Flow a (—) outside, b (- -) within the measuring range.
A0001273
•STANDARD
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.
A0001274
TIME CONSTANT
(4005)
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).
