Key points
Check all components that can affect the sprayer’s output
Have the right equipment on hand to calibrate all components
Never assume that the equipment you use to calibrate is accurate – check (by weight)
Do not assume that the controller settings or increments on the spray tank are correct
Know what to measure and how to make adjustments to improve your accuracy
