Calibration Procedures
The calibration test should be done to confirm the settings of the required seed rate and is done with the
drill stationary and level. Please ensure that you have read the previous section.
1 Power On the console.
2 You will be presented with the BIN SETUP screen. Make any changes to product or target sowing
rates now.
3 Prepare a suitable area for weighing and setup the scales. Tare the scales with the same container
that will be used to weight the product. Scales must be accurate to 2 grams
4 Refer to the sowing chart (page ?) for the chosen product. Set the Shutter Slides, Bottom Flaps and
Metering Wheels in accordance with the sowing chart.
5 Remove the calibration trays from the bracket on the seedbox. Place the trays on the calibration tray
brackets on the seedbox.
6 Push down all the clear plastic seed directors to redirect seed into the calibration trays.
7 For the calibration check, half fill the appropriate box with product. If this is not possible, make sure
the product is evenly distributed over all the seeder units in the box.
8 The calibration process can be in initiated in two ways:
(i) By pressing the appropriate ‘PRIMING SWITCH’
(ii) Via the SETUP menu.
Each of these methods are described in the next few pages.
The PRIMING SWITCH method is easier and more convenient.
(i) Calibration via PRIMING SWITCH (recommended)
1 Press and hold the appropriate ‘PRIMING SWITCH’ for 1
second then release.
2 The Operating Screen will change as shown. It is likely the
operator will be standing near the priming switches at this
time so will not see the display. It is only after weighing the
dispensed product that the operator need visit the tractor cab.
If the operator presses ‘STOP’ the calibration will be cancelled;
no seting will be altered. This may occur if the priming switch is
pressed to just prime the seeder units or test the motor drive.
