If a nozzle pattern check shows a problem, the output and/or uniformity is off by more than what percentage?

If a nozzle pattern check shows a problem, the output and/or uniformity is off by more than what percentage?

• A. More than 50%
• B. More than 5%
• C. More than 25%
• D. More than 75%

Answer: (A)

The main idea this question tests is the tolerance for nozzle pattern checks—how much deviation in spray output or distribution is still considered acceptable. If the measured output or the pattern uniformity is off by more than half, that signals a serious malfunction that should be fixed before spraying. This large threshold (more than 50%) matters because minor variations are common and can be acceptable, but a deviation greater than half means some areas would receive far too little or too much material, leading to ineffective pest control, potential crop injury, or environmental risk. In practice, such a substantial deviation triggers maintenance actions like cleaning or replacing a nozzle, correcting pressure, or adjusting alignment to restore even coverage. Smaller deviations (like a few percent) are often tolerated in normal operation, while a deviation of more than half is a clear red flag that the system is not performing properly.
