Postrequisites
Choose Menu → Service Tools → Service Data → View Process Variables and verify the value for External
Temperature.

If the value is not correct:
• Ensure that the external device and the meter are using the same measurement unit.
• For polling:
— Verify the wiring between the meter and the external device.
— Verify the HART
®
tag of the external device.
Modify matrix names and labels using the display
For convenience, you can change the name of a concentration matrix and the label used for its measurement
unit. This does not affect measurement.
Procedure
1. Choose Menu → Configuration → Process Measurement → Concentration Measurement → Configure
Matrix.
2. Select the matrix that you want to modify.
3. Set Matrix Name to the name that will be used for this matrix.
4. Set Concentration Unit to the label that will be used for the concentration unit.
If you want to use a custom label, you can use the display to select Special. However, you cannot use
the display to configure the custom label. You must use another tool to change the label from Special to
a user-defined string.
Modify extrapolation alerts using the display
You can enable and disable extrapolation alerts, and set extrapolation alert limits. These parameters control
the behavior of the concentration measurement application but do not affect measurement directly.
Each concentration matrix is built for a specific density range and a specific temperature range. If line density
or line 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.
Each concentration matrix has its own extrapolation alert limits.
Procedure
1. Choose Menu → Configuration → Process Measurement → Concentration Measurement → Configure
Matrix.
2. Select the matrix that you want to modify.
3. Set Extrapolation Limit to the point, in percent, at which an extrapolation alert will be posted.
4. Choose Menu → Configuration → Process Measurement → Concentration Measurement → Configure
Application → Extrapolation Alerts.
5. Enable or disable the high and low limit alerts for temperature and density as desired.
Example: Extrapolation alerts in action
If Extrapolation Limit is set to 5%, High Limit (Temp) is enabled, and the active matrix is built for a
temperature range of 40°F (4.4°C) to 80°F (26.7°C), a high-temperature extrapolation alert will be posted if
line temperature goes above 82°F (27.8°C).
