smaller than the value assigned for the 0/4 mA current in the 0/4 mA value parameter
(→  108).
Dependency
The unit depends on the process variable selected in the Assign curr. parameter
(→  106).
Example
• Value assigned to 0/4 mA = –250 m 3 /h
• Value assigned to 20 mA = +750 m 3 /h
• Calculated current value = 8 mA (at zero flow)
If the
Forward/Reverse option is selected in the Measuring mode parameter
(→  110), different signs cannot be entered for the values of the 0/4 mA value
parameter (→  108) and 20 mA value parameter (→  109). The diagnostic message
S441 Curr.output 1 to n is displayed.
Configuration examples
Observe the configuration examples for the 0/4 mA value parameter (→  108).
Measuring mode 
Navigation  Expert → Output → Curr.output 1 to n → Measuring mode (0351–1 to n)
Prerequisite One of the following options is selected in the Assign curr. parameter (→  106):
• Volume flow
