Set Reference Temperature Values For Specific Gravity Using A Basic Ff Host; Modify Matrix Names And Labels Using A Basic Ff Host - Emerson Micro Motion 2700 Configuration And Use Manual

4.9.1 Set reference temperature values for specific gravity
using a basic FF host
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.
To check the setting of Derived Variable, read the value of the Derived Variable parameter
in the Concentration Measuremnt TB.

Important
Do not change the setting of Derived Variable. If you change the setting of Derived Variable, all
existing concentration matrices will be deleted from transmitter memory.
Procedure
Write the desired values into the appropriate parameters in the Concentration
Measuremnt TB for Reference Temperature, Water Reference Temperature, and Water
Reference Density.
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 want to.

Modify matrix names and labels using a basic FF host

For convenience, you can change the name of a concentration matrix and the label used
for its measurement unit. This does not affect measurement.

Choose the matrix you want to modify by writing to the Matrix Being Configured
parameter in the Concentration Measuremnt TB. Each saved matrix has a unique
value of 0 through 5.
Write the desired values into the Matrix Name and Concentration Unit parameters in
the Concentration Measuremnt TB.
