Calibration compensates for factors like nozzle wear and liquid viscosity. This lesson explains when and how to calibrate the FP700&#8217;s spray system flow meter using the Agri Assistant App.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>When to Calibrate:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>First Use:<\/strong> Before the very first spraying operation with the drone.<\/li>\n\n\n\n<li><strong>Nozzle Change:<\/strong> After replacing spray nozzles.<\/li>\n\n\n\n<li><strong>Liquid Change:<\/strong> After switching to a liquid with significantly different viscosity.<\/li>\n\n\n\n<li><strong>Inaccuracy Detected:<\/strong> If you observe a significant discrepancy (>10%) between the actual area covered\/volume used and the planned amount.<\/li>\n\n\n\n<li><strong>Component Replacement:<\/strong> After replacing the pump or flow meter components.<\/li>\n\n\n\n<li><strong>Periodically:<\/strong> As part of routine maintenance, especially after extended use.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Calibration Procedure:<\/strong><\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Preparation:<\/strong>\n<ol class=\"wp-block-list\">\n<li>Place the drone on a stable, level surface.<\/li>\n\n\n\n<li>Fill the spray tank partially with clean water (or the liquid you will be spraying, if viscosity calibration is needed). Ensure there&#8217;s enough liquid for the calibration process but avoid overfilling initially if weight calibration is part of the process.<\/li>\n\n\n\n<li>Ensure batteries are charged and the drone and RC are powered on and connected.<\/li>\n<\/ol>\n<\/li>\n\n\n\n<li><strong>Purge <\/strong><strong>Air<\/strong><strong>:<\/strong> Before calibration, run the pump manually for a short period (using the &#8222;Manual Spray Test&#8220; function or RC button) to purge any air from the lines and ensure a consistent liquid flow.<\/li>\n\n\n\n<li><strong>Navigate in App:<\/strong> Open the Agri Assistant App. Go to <strong>Settings -> Spraying Settings<\/strong> (or similar path).<\/li>\n\n\n\n<li><strong>Find Calibration:<\/strong> Locate the &#8222;Flow Meter Calibration&#8220; option.<\/li>\n\n\n\n<li><strong>Follow App Prompts:<\/strong> Tap &#8222;Flow Meter Calibration&#8220; and carefully follow the step-by-step instructions displayed in the app. This process typically involves:\n<ol class=\"wp-block-list\">\n<li><strong>Weight Sensor<\/strong><strong> Tare\/Check (If applicable):<\/strong> The app might first require a tare of the weighing system with the tank empty or check its baseline reading. Ensure the drone is not disturbed during this.<\/li>\n\n\n\n<li><strong>Adding Known <\/strong><strong>Volume<\/strong><strong>\/Weight:<\/strong> The app may instruct you to add a precise volume or weight of water\/liquid to the tank. Use accurate measuring tools.<\/li>\n\n\n\n<li><strong>Running the Pump:<\/strong> The app will automatically run the pump at various flow rates for specific durations.<\/li>\n\n\n\n<li><strong>Measuring <\/strong><strong>Output<\/strong><strong> (Manual Method):<\/strong> Some systems might require manually collecting and measuring the sprayed volume during the test.<\/li>\n\n\n\n<li><strong>Automatic Calculation:<\/strong> Based on sensor readings (weight change or flow meter pulses), the app calculates the calibration factors.<\/li>\n<\/ol>\n<\/li>\n\n\n\n<li><strong>Confirmation:<\/strong> The app will indicate whether the calibration was successful. If it fails, check for issues like air in the lines, pump problems, sensor errors, or disturbances during the process, and attempt calibration again.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Regular and accurate calibration ensures your spraying operations are precise, saving chemicals and protecting your crops.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Accurate flow meter calibration is essential for precise application rates when spraying.
