What is calibration?

• A. Measuring container capacity
• B. Setting spray color
• C. Checking label
• D. Adjust application rate

Answer: (D)

Calibration is making sure the sprayer delivers the exact amount of chemical per acre that the label requires. It means testing the spray output at the operating pressure and linking that to your travel speed and spray width so the rate per acre matches the target. If the measured output is off, you adjust components such as nozzles, pressure, or speed until the actual rate aligns with the labeled rate. This helps ensure effectiveness, reduces waste and environmental risk, and keeps you compliant with label directions. The idea isn’t about how much the container can hold, changing spray color, or merely checking the label—calibration focuses on setting and verifying the application rate.
