7. Select sensor to calibrate from Pressure Sensor drop-down menu.

8. Select either Voltage-based Calibration button or Operation-based Calibration button.

Use Voltage-based Calibration when pressure sensor slope is known.

To use Operation-based Calibration, two calibration points must be determined since slope is unknown. Rate controller automatically measures voltage at zero pressure. Second calibration point is measured at an operator desired pressure.

A - Voltage Slope

B - Accept Button

1. IMPORTANT: Verify with sensor manufacturer that sensor can accept 12 V power.

   Ensure sensor has 12 V power supply.

2. NOTE: For Raven pressure sensors with a 12 V power supply, slope is 16 mV/psi.

   Enter slope (A) from pressure sensor manufacturer.

3. Select Accept button (B).
