4. In Global Config, set Derived Variable to the derived variable that your matrix is
designed for.
Important
• All concentration matrices on your transmitter must use the same derived variable. If you
are using one of the standard matrices from Micro Motion, set Derived Variable to Mass Conc
(Density). If you are using a custom matrix, see the reference information for your matrix.
• If you change the setting of Derived Variable, all existing concentration matrices will be
deleted from transmitter memory. Set Derived Variable before loading concentration
matrices.
5. Load one or more matrices.
a. In Curve Specific Config, set Curve Configured to the location to which the matrix
will be loaded.
b. Click Load this curve from a file, navigate to the matrix file on your PC, and load it.
c. Repeat until all required matrices are loaded.
6. Set up extrapolation alarms.
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 alarms are used to notify the operator that
extrapolation is occurring.
a. In Curve Specific Config, set Curve Configured to the matrix that you want to
configure.
b. Set Alarm Limit to the point, in percent, at which an extrapolation alarm will be
posted.
Example: If Alarm Limit is set to 5%, Enable Temp High is checked, 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
7. Select the label that will be used for the concentration unit.
a. In Curve Specific Config, set Curve Configured to the matrix that you want to
configure.
b. Select the desired label from the Units list.
c. If you set Units to Special, enter the custom label.
8. Determine how the transmitter will obtain temperature data for the concentration
measurement calculations, and perform the required setup.
