— Perform an mA Input trim.
— Adjust the mA Input damping value.
• For digital communications:
— Verify that the host has access to the required data.
— Verify that the host is writing to the correct register in memory, using the correct data type.
5.1.3 Set up the API referral application using the Field
Communicator
This section guides you through the tasks required to set up and implement the API referral application.
Enable the API referral application using the Field Communicator
The API referral application must be enabled before you can perform any setup. If the API referral application
was enabled at the factory, you do not need to enable it now.
Prerequisites
The API referral application must be licensed on your transmitter.
Volume Flow Type must be set to Liquid.
Procedure
1. Choose Configure > Manual Setup > Measurements > Optional Setup > GSV and ensure that Volume
Flow Type is set to Liquid.
This parameter is available only if API referral or concentration measurement is not enabled. If you do
not see this parameter, it is already set correctly.
2. If the concentration measurement application is enabled, disable it.
The concentration measurement application and the API referral application cannot be enabled
simultaneously.
3. Enable the API referral application.
Configure API referral using the Field Communicator
The API referral parameters specify the API table, measurement units, and reference values to be used in
referred density calculations.
Prerequisites
You will need API documentation for the API table that you select.
Depending on your API table, you may need to know the thermal expansion coefficient (TEC) for your process
fluid.
You must know the reference temperature and reference pressure that you want to use.
Procedure
1. Choose Configure > Manual Setup > Measurements > Optional Setup > API Referral.
