If you are using the 4 to 20 mA output, you can trim the output at 4 mA and 20 mA or at other values by connecting a digital voltmeter and precision resistor in the output loop and adjusting the output with this procedure. Set up the calibration equipment.
Application of pressure is not required. This adjustment has no effect on the internal digital interpretation of pressure or on the displayed and transmitted digital values representing the applied pressures. It only trims the conversion of the digital values of pressure to the transmitted 4 to 20 mA analog signal.
