Calibrate Menu
The “Calibrate” menu contains links to three different applications: Sensor
Trim, D/A Trim, and Scaled D/A Trim.
From the “Sensor Trim” link, you can access the calibration options for the
Differential Pressure, Static Pressure, and Temperature process variables.
Additionally, you can change the Atmospheric Pressure value and restore the
D/A converter to its factory default setting.
