Pressure Compensation
Not all sensors or applications require pressure correction factors. For the pressure correction values to be used, obtain the pressure effect values from the product data sheet for your sensor, then reverse the signs (e.g., if the pressure effect is 0.000004, enter a pressure correction factor of
9.2.3Pressure measurement unit
The default measurement unit for pressure is PSI. In other words, the transmitter expects to receive pressure data in psi. If you will use a different pressure measurement unit, you must configure the transmitter to use that measurement unit.
