Concentration process variables are now available on the transmitter. You can view and
report them in the same way that you view and report other process variables.

Configuration and Use Manual
b. Set Polling Control to Poll as Primary or Poll as Secondary, and click Apply.
Tip
• Poll as Primary: No other HART masters will be on the network.
• Poll as Secondary: Other HART masters will be on the network. The Field Communicator
is not a HART master.
c. Set External Device Tag to the HART tag of the external temperature device, and
select Apply.
If you chose to use a static temperature value, set External Temperature to the value
to use, and select Apply.
If you want to use digital communications, select Apply, then perform the necessary
host programming and communications setup to write temperature data to the
transmitter at appropriate intervals.
Set Active Matrix to the matrix to be used for measurement.
Choose Online > Configure > Manual Setup > Measurements > Density and set
Density Unit to match the density unit used by your matrix.
Choose Online > Configure > Manual Setup > Measurements > Temperature and set
Temperature Unit to match the temperature unit used by your matrix.
Choose Online > Configure > Manual Setup > Measurements and click Concentration
Measurement.
Enable or disable matrix switching, as desired.
Set up extrapolation alerts.
Each concentration matrix is built for a specific density range and a specific
temperature range. If process density or process temperature goes outside the
range, the transmitter will extrapolate concentration values. However, extrapolation
may affect accuracy. Extrapolation alerts are used to notify the operator that
extrapolation is occurring.
a. Click Next.
b. On the Matrix Configuration page, set Matrix Being Configured to the matrix that
you want to configure.
c. Modify the matrix name if desired.
d. Set Extrapolation Alert Limit to the point, in percent, at which an extrapolation
alert will be posted.
e. Choose Online > Configure > Alert Setup > CM Alerts.
