How To Calibrate Pressure:
Calibration of pressure allows up to 3 pressure sensor readings (voltage based) to be shown on the display. These pressures are not used for control, but for pressure monitoring only.
Setup:
When calibrating, it is best to relieve pressure in the system by bleeding all boom pressure including drip check diaphragms and use zero PSI for the set point.
Follow These Steps:
Determine the current pressure in the system to use as the set point (typically 0 as stated above). On the Ag Leader® Integra and Versa displays, select the configuration and press the wrench, then calibrate pressure, and select which sensor to calibrate (Main, Agitation, Aux). On the InSight go to thecontroller tab, select the controller, then select the appropriate sensor to calibrate.
Next enter a pressure value as a Set Point; this will be the current system pressure read from an analog gauge or true zero pressure.
Enter the Voltage to Pressure Ratio in mV/PSI
Raven, Ag Leader pressure sensors will be 16 mV/PSI, Dickey-John sensors will be 45 mV/PSI.
(Metric: Raven- 230 mV/bar, Dickey-John- 650 mV/bar)
Calibration is then complete
***If sensor is not supported or does not work with the 16 or 45 mV/PSI setting, it can be calculated using the following formula:
mV/PSI = Signal Range/Max Pressure mV/bar = Signal Ranger/Max Pressure
Signal Range= Max voltage of the sensor-Min voltage of the sensor*
Max Pressure= Maximum Pressure the sensor is capable of reading*
*Can generally be found on a tag on the sensor
