Simulate current output
This forces a fixed output current in the range 4 to 20 mA. This feature
temporarily
overrides the
normal function of the transmitter’s PV driving the 4–20 mA Current Output until exiting to the
previous menu.
Note
The simulation is automatically cancelled after 20 minutes, and the output current returns to
representing the transmitter’s PV.
Field Communicator or AMS Device Manager
To fix the output current
1.
From the
