CALIBRATING THE PRESSURE GAUGE
The pressure tap on the Raven Sprayer Control system is located away from the nozzles, thus, there can be a pressure
difference between nozzle pressure and gauge pressure at the console. Therefore, for best results, Raven recom-
mends the following procedure:
1. When the sprayer is ready and the tank is filled with water (No chemicals at this time), attach an accurate
pressure gauge to a nozzle in place of the spray tip.
2. Start up the pump, turn on the electric shut-off valves and adjust the pressure control valve so that the desired
pressure is maintained on the gauge at the nozzle.
3. Because of pressure drops through the system, the pressure shown on the gauge in the console may read
slightly higher than the gauge at the nozzle. Use this console pressure reading as your reference point for
maintaining the desired pressure at the nozzle.
