Important
When you load a matrix, if the temperature unit is not correct, concentration data will be
incorrect. The temperature units must match at the time of loading. You can change the
temperature unit after the matrix is loaded.
3. Choose Device Tools > Configuration > Process Measurement > Concentration Measurement.
The Concentration Measurement window is displayed. It is organized into steps that
allow you to perform several different setup and configuration tasks. For this task,
you will not use all the steps.
4. In Step 1, ensure that the setting of Derived Variable matches the derived variable
used by your matrix. If it does not, change it as required and click Apply.
Important
If you change the setting of Derived Variable, all existing concentration matrices will be deleted
from transmitter memory. Verify the setting of Derived Variable before continuing.
5. Load one or more matrices.
a. In Step 2, set Matrix Being Configured to the location (slot) to which the matrix will
be loaded.
b. Click Load Matrix from a File, navigate to the matrix file on your computer, and load
it.
c. Repeat until all required matrices are loaded.
6. (Optional) Set the density and temperature units to the units you want to use for
measurement.

When Derived Variable is set to Specific Gravity, you must set the reference temperature to be
used for density measurement and the reference temperature of water, and then verify
the density of water at the configured reference temperature. The two reference
temperature values affect specific gravity measurement.
Additionally, the two reference temperature values affect any concentration process
variable that is calculated by equation, rather than by matrix, because the equations are
based on specific gravity.
Typically, the two reference temperature values are the same, but this is not required.
