An uneven surface will cause calibration failure.<\/li>\n\n\n\n<li>Ensure the spreader tank is completely empty.<\/li>\n\n\n\n<li>Have a sufficient quantity of the <em>exact<\/em> material you intend to spread ready for the calibration.<\/li>\n\n\n\n<li>Power on the drone and RC, connect via the Agri Assistant App.<\/li>\n<\/ol>\n<\/li>\n\n\n\n<li><strong>Navigate in App:<\/strong>\n<ol class=\"wp-block-list\">\n<li>Go to <strong>Settings -> Spreader Settings<\/strong> (or similar).<\/li>\n\n\n\n<li>Ensure the correct Spreader Type (e.g., SP5) and Material Type are selected. If using a new material, add and name it in the material list.<\/li>\n\n\n\n<li>Select the correct Feed Roller size being used (for SP5).<\/li>\n<\/ol>\n<\/li>\n\n\n\n<li><strong>Start Calibration:<\/strong>\n<ol class=\"wp-block-list\">\n<li>Locate and tap the &#8220;Material Calibration&#8221; or &#8220;Weighing Calibration&#8221; button.<\/li>\n<\/ol>\n<\/li>\n\n\n\n<li><strong>Follow App Prompts:<\/strong> The app will guide you through the steps:\n<ol class=\"wp-block-list\">\n<li><strong>Confirm Empty &amp; Level:<\/strong> Verify the tank is empty and the drone is level. The app may display the current deviation angle. Tap &#8220;Complete&#8221; or &#8220;Next&#8221;.<\/li>\n\n\n\n<li><strong>Tare Calibration:<\/strong> The app will likely perform an automatic tare calibration of the empty tank. Do not disturb the drone during this step. You might have an option to skip if taring was done recently.<\/li>\n\n\n\n<li><strong>Add Material:<\/strong> The app will instruct you to fill the tank completely (or to a specific calibration weight) with the chosen material. Fill adequately as insufficient material can cause failure. Tap &#8220;Complete&#8221; or &#8220;Next&#8221;.<\/li>\n\n\n\n<li><strong>Automatic Calibration Run:<\/strong> The system will automatically run the spreader mechanism (feed roller, spinning disc) at various speeds to measure the discharge rate versus the weight change. <strong>Do not touch or disturb the drone during this process<\/strong>.<\/li>\n<\/ol>\n<\/li>\n\n\n\n<li><strong>Calibration Curve &amp; Confirmation:<\/strong>\n<ol class=\"wp-block-list\">\n<li>Upon successful completion, the app will display a calibration curve showing the relationship between the feed mechanism speed and the discharge rate (kg\/min). A smooth curve indicates a good calibration.<\/li>\n\n\n\n<li>If the calibration fails or the curve is erratic, ensure all preparation steps were followed correctly (level ground, empty tank start, sufficient material, no disturbances) and repeat the calibration.<\/li>\n<\/ol>\n<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Accurate spreader calibration ensures you apply the correct amount of seed, fertilizer, or other granular material consistently across your field.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Accurate calibration of the weighing system is crucial for precise granular application when using the spreader payload.
