Pressure Measurement Unit controls the measurement unit used for pressure. This unit must match the unit
used by the external pressure device.
Pressure data is used for pressure compensation and for API Referral. The device does not measure pressure
directly. You must set up a pressure input.
Procedure
Set Pressure Measurement Unit to the desired unit.
Default: psi
4.7.1 Options for Pressure Measurement Unit
The transmitter provides a standard set of measurement units for Pressure Measurement Unit. Different
