6.4.2.5
Fixed output current
Parameter: P08
Menu path:
OUTPUT SETUP / ANALOG OUTPUT / MANUAL VALUE
Default value:
4 mA
Description:
Parameter for setting the fixed output current
Values between 3.8 and 20.5 can be entered. The output current will be set to the entered
value and analogue transmission will be suspended. . (see
6.4.2.1
)
The set (current) value overwrites the 4mA output of HART multidrop mode!
6.4.3.
