8.4 Set up concentration measurement using a field
communicator
This section guides you through the tasks required to set up, configure, and implement concentration
measurement.
8.4.1 Enable the concentration measurement application using a
field communicator
The concentration measurement application must be enabled before you can perform any setup. If the
concentration measurement application was enabled at the factory, you do not need to enable it now.
Procedure
1. Choose Overview → Device Information → Applications → Enable/Disable Applications.
2. Enable the concentration measurement application.
8.4.2 Configure a concentration measurement matrix using a field
communicator
A concentration measurement matrix defines the relationship between density and concentration for your
process gas. You can configure up to six matrices.
Prerequisites
You must know the primary and secondary constituents of your process gas, and the density of each
constituent in pure form.
Procedure
1. Choose Configure → Manual Setup → Measurements → Conc Measure (CM) → Configure Matrix.
2. Set Matrix Being Configured to the matrix you want to configure.
3. Enter a name for the matrix.
4. Set Concentration Units to the label to used for the measurement unit.
This selection does not affect measurement. It only selects a label.
5. If you set Concentration Units to Special, enter a string for the custom label.
6. Choose Enter Matrix Data.
7. Enter the density of the primary constituent of your process gas, in its pure form.
