Calibration of sprayer via practical method
Do a complete checkup of the equipment:
• Suction filter, line filter – cleaning.
• Hoses – check for holes or bents.
• Pressure regulator - components valve
seat, valve and spring, if not worn or lo-
cked by impurities.
• Pump - check if there are no leaks and if
there is enough lubricating oil.
• Nozzles - not worn down, don´t differ in
flow by more than 10% flow and if the
nozzle filters are clean.
Once all items have been checked, sprayer
calibration can begin.
1. Mark 50 meters on the terrain to be treated.
2. Fill up the sprayer with clean water.
3. Position the machine at least 5 meters
before the first mark.
4. Add TDP at 540 rpm.
5. Choose the working speed.
6. Through the chemicals control, start the
spraying.
7. When the machine passes through the
first peg, start the chronometer.
8. When the machine passes through the
second peg, stop the chronometer.
9. Write down the time the sprayer took to
go through the 165 feet.
10. In irregular terrains repeat this opera-
tion several times and make an average.
