configuration that is stored for the selected input or output type, and the stored configuration may not be
appropriate for your process.
After verifying channel and output configuration, return the control loop to automatic control.

8.2 Configure an mA Output

Use an mA Output to report current values of process variables. The mA signal varies between 4 mA and
20 mA in proportion to the current value of the assigned process variable.
Depending on your purchase order and channel configuration, your transmitter may have 0–3 mA Outputs.
Channel A is always mA Output 1, and Channel B and Channel C can be configured as mA Output 2 and
mA Output 3 respectively.
Note
Channel A also supports HART/Bell 202 communications, superimposed on the mA signal. HART is not
available on Channel B or Channel C.

8.2.1 Configure mA Output Source

Display Menu > Configuration > Inputs/Outputs > Channel x > I/O Settings > Source
ProLink III Device Tools > Configuration > I/O > Outputs > mA Output x
Field Communicator Configure > Manual Setup > Inputs/Outputs > Channel x > mA Output x > mAOxSource
mA Output Source specifies the process variable that is reported by the mA Output.
Prerequisites
• If you plan to configure the output to report volume flow, ensure that you have set Volume Flow Type as
desired: Liquid or Gas Standard Volume.
• If you plan to configure an output to report a concentration measurement process variable, ensure that
the concentration measurement application is configured so that the desired variable is available.
• If you are using the HART variables, be aware that changing the configuration of mA Output 1 Source will
change the configuration of the HART Primary Variable (PV).
Note
mA Output 2 Source is not tied to the HART secondary variable. You can configure these independently. This
is different from previous Micro Motion Coriolis transmitters.
Procedure
Set mA Output Process Variable as desired.
Defaults:
• mA Output 1: Mass Flow Rate
• mA Output 2: Density
• mA Output 3: Temperature
