Configuration and Use Manual
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.
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.
Example: If Alarm Limit is set to 5%, the high-temperature extrapolation alert is
enabled, and the matrix is built for a temperature range of 40 °F to 80 °F, an
extrapolation alarm will be posted if process temperature goes above 82 °F
Select the label that will be used for the concentration unit.
a. Click Next.
b. On the Concentration Measurement page, set Concentration Units to the
desired label.
c. Set Concentration Units to the desired label.
d. If you set Units to Special, enter the custom label.
e. Click Finish.
Determine how the transmitter will obtain temperature data for the concentration
measurement calculations, and perform the required setup.
