b) To load a .xml file from your computer, click Load Matrix from File, navigate to the file, and load
it.
c) To load a .matrix file from your computer, click Load Matrix from My Computer, navigate to
the file, and load it.
d) To load a .matrix file from the transmitter's internal memory, click Load Matrix from 4200
Device Memory, navigate to the file on the transmitter, and load it.
e) Repeat until all required matrices are loaded.
6. Optional: If you loaded an .xml file, set the density and temperature units to the units you want to use
for measurement.
Set reference temperature values for specific gravity using ProLink III
When Derived Variable is set to any option based on specific gravity, you must set the reference temperature
for water, then verify the density of water at the configured reference temperature. These values affect
specific gravity measurement.
This requirement applies to the following derived variables:
• Specific Gravity
• Concentration (Specific Gravity)
• Mass Concentration (Specific Gravity)
• Volume Concentration (Specific Gravity)
Procedure
1. 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.
2. Scroll to Step 2, set Matrix Being Configured to the matrix you want to modify, and click Change
Matrix.
3. Scroll to Step 3, then perform the following actions:
a) Set Reference Temperature for Referred Density to the temperature to which line density will
be corrected for use in the specific gravity calculation.
b) Set Reference Temperature for Water to the water temperature that will be used in the specific
gravity calculation.
c) Set Water Density at Reference Temperature to the density of water at the specified reference
temperature.
The transmitter automatically calculates the density of water at the specified temperature. The
new value will be displayed the next time that transmitter memory is read. You can enter a
different value if you prefer.
4. Click the Apply button at the bottom of Step 3.
