Calibrate the dispenser rotation
Turn the drive wheel so that the Hectare Mini learns how many dispenser pulses go with how many wheel pulses — needed before "Rotation speed control" can watch the shaft speed.
With “Rotation speed control” at “Yes”, a dispenser sensor watches whether the shaft turns as fast as the travel speed demands (Dispenser shaft sensor). For that the panel must know the ratio between the pulses of the speed sensor and the pulses of the dispenser sensor. The calibration measures it and writes “Wheel, pulses” and “Dispenser pulses”.
Before you start: the speed sensor and the dispenser sensors to be calibrated must be under control and must answer. You need the “Agronomist” level (Enable the Agronomist level). Raise the machine so that the drive wheel can be turned, or be ready to move it.
“Settings” → “Seeding machine parameters”. Select “Dispenser calibration”.
Choose with “PLUS” / “MINUS” which dispensers to calibrate: “ALL”, or the number of one dispenser.
Press “MENU”. The “Calibration” screen opens with a progress bar at 0 %.
Turn the drive wheel. The bar fills as pulses come in from the wheel and from every dispenser being calibrated.
At 100 % — at least 100 pulses from each — the panel beeps and shows “Stop rotation!”. Stop turning.
When no pulse has come for two seconds, the panel stores the values and shows “Done”; the “Seeding machine parameters” menu returns.

“BACK” at any moment aborts with “Calibration canceled!”; nothing changes.
| The panel shows | Meaning |
|---|---|
| “Sensor not controlled! Calibration canceled!” | The speed sensor or a dispenser sensor to be calibrated is out of control. Take it into control (Take a sensor into or out of control). |
| “Connection lost with the sensor! Calibration canceled!” | The speed sensor or a dispenser sensor does not answer, at the start or during the calibration. |
The more you turn before “Stop rotation!”, the better: the values are scaled down by themselves if the count grows beyond what they can hold.
Calibrate again after any change to the drive between the wheel and the dispenser — sprockets, gearbox or variator.
