Configure process measurement applications
April 2019
Procedure
1. Choose Configure > Manual Setup > Measurements > Optional Setup > API Referral.
2. Choose API Referral Setup.
3. Specify the API table that you want to use to calculate referred density.
Each API table is associated with a specific set of equations.
a) Set API Table Number to the number that matches the API table units that you want to use for
referred density.
Your choice also determines the measurement unit to be used for temperature and pressure,
and the default values for reference temperature and reference pressure.

(1) Used only with API Table Number= 6, 24, or 54.
(2) Used only with API Table Number = 23, 24, 53, 54, 59, or 60.
API Table Number and API Table Letter uniquely identify the API table. The selected API table is
displayed, and the meter automatically changes the density unit, temperature unit, pressure unit,
reference temperature, and reference pressure to match the API table.
