Calibrating the Pressure Sensor

Before calibrating the Pressure Sensor make sure you have selected which Type of Pressure Sensor is connected to the system (page 8-38) and what Calibration Method you are going to use (page

8-43).

NOTICE NOTICE

A Manual Pressure gauge must be fitted to the system to determine the actual pressure for calibration purposes.

1.Select RESTORE FACTORY DEFAULTS at the bottom of Tank Pressure window (Figure 10-1 on page 10-1)

2.Select CALIBRATE SENSOR in the Tank Pressure window (Figure 10-1 on page 10-1)

3.Follow the on screen directions to calibrate the Pressure Sensor

To calibrate the Pressure Sensor the console will take a zero reading of the pressure when the pump is switched OFF. Then another reading of the pressure when the pump is at operating pressure. You will enter the actual pressure as read from a Glass Pressure Gauge, using the screen keyboard.

4.Once the calibration is complete, check the Pressure Readout from the Working screen and compare it against the Glass Pressure Gauge.

If the difference is more than 10% then make note of the Actual Pressure and the Pressure Readout from the Working screen.
