D - Sensor 2 Voltage-based Calibration

E - Sensor 2 Operation-based Calibration

There are two options for calibrating a pressure sensor. The Operation Based Calibration requires that two calibration points be entered and is used when the slope of the pressure sensor is not known. The Voltage Based Calibration can be used when the slope of the pressure sensor is known and only requires a zero point.

1. Ensure the NH3 tank is disconnected from the control valves and the pressure sensor is at atmospheric pressure.

2. Press the Calibration button for the desired type of calibration to begin test and set zero point.

Voltage-based Calibration

1. Ensure the sensor has 12V power supply. NOTE: Check with sensor manufacturer to ensure that sensor can accept 12V power.
   
2. Enter the slope as reported by the implement pressure gauge manufacturer in the box below.

3. Select Accept.

NOTE: Sensor power can be connected to the ECU Power pin (pin 26 of 37-pin connector) to provide 12V.

NOTE: For Raven pressure sensors with a 12V power supply the slope will be 16 mV/psi.
