2.4 (Optional) Adjust digital communications
settings
Change the communications parameters to site-specific values.
Important
If you are changing communications parameters for the connection type that you are using, you will
lose the connection when you write the parameters to the transmitter. Reconnect using the new
parameters.

Verify mass flow measurement

Check to see that the mass flow rate reported by the transmitter is accurate. You can use
any available method.

Verify the zero

Verifying the zero helps you determine if the stored zero value is appropriate to your
installation, or if a field zero can improve measurement accuracy.
The zero verification procedure analyzes the Live Zero value under conditions of zero flow,
and compares it to the Zero Stability range for the sensor. If the average Live Zero value is
within a reasonable range, the zero value stored in the transmitter is valid. Performing a
field calibration will not improve measurement accuracy.
Configuration and Use Manual
To change the communications parameters using ProLink III, choose Device Tools >
Configuration > Communications.
To change the communications parameters using the Field Communicator, choose
On-Line Menu > Configure > Manual Setup > Inputs/Outputs > Communications.
Connect to the transmitter with ProLink III and read the value for Mass Flow Rate in
the Process Variables panel.
Connect to the transmitter with the Field Communicator and read the value for Mass
Flow Rate.
