4.9.4 Select the active concentration matrix using a basic FF
host
You must select the concentration matrix to be used for measurement. Although the
transmitter can store up to six concentration matrices, only one matrix can be used for
measurement at any one time.
Choose the matrix you want to use by writing to the Active Matrix parameter in the
Concentration Measuremnt TB. Each saved matrix has a unique value of 0 through 5.

Configure pressure compensation

Pressure compensation adjusts process measurement to compensate for the pressure
effect on the sensor. The pressure effect is the change in the sensor's sensitivity to flow
and density caused by the difference between the calibration pressure and the process
pressure.
Tip
Not all sensors or applications require pressure compensation. The pressure effect for a specific
sensor model can be found in the product data sheet located at www.emerson.com. If you are
uncertain about implementing pressure compensation, contact customer service.
Prerequisites
You will need the flow factor, density factor, and calibration pressure values for your
sensor.
