VALUE 20 mA
Use this function to assign the 20 mA current a full scale value.
Positive and negative values are permitted. The required measuring range is
defined by defining the VALUE 20 mA.
In the SYMMETRY measuring mode (see Page 108), the value assigned
applies to both flow directions; in the STANDARD measuring mode it applies
only to the flow direction selected.
User input:
5-digit floating-point number, with sign
Factory setting:
Depends on nominal diameter and country, [value] / [dm
3
...m
3
or
US-gal...US-Mgal]
Corresponds to the factory setting for the full scale value (see Page 116 ff.).
!
Note!
• The appropriate unit is taken from the SYSTEM UNITS group (see Page 93).
• The value for 4 mA always corresponds to the zero flow (0 [unit]). This value
is fixed and cannot be edited.
TIME CONSTANT
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).
User input:
Fixed-point number 0.01...100.00 s
Factory setting:
1.00 s
