6.1 Configure the mA Output

The mA Output is used to report the configured process variable. The mA Output parameters control how the

process variable is reported.

Your transmitter has two mA Outputs.

Important

Whenever you change an mA Output parameter, verify all other mA Output parameters before returning the

meter to service. In some situations, the transmitter automatically loads a set of stored values, and these

values may not be appropriate for your application.

Use mA Output Process Variable to select the variable that is reported over the mA Output. This variable is

applied automatically to the Frequency 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 Process

Variable will change the configuration of the HART Primary Variable (PV) and/or the HART Secondary

Variable (SV).

Procedure

Set mA Output Process Variable as desired.

Default settings are as follows:

•

Primary mA Output: Mass Flow Rate

•

Secondary mA Output: Density

Postrequisites

If you changed the setting of mA Output Process Variable, verify the settings of Lower Range Value (LRV)

and Upper Range Value (URV).
