Calibration
Calibration
The calibration test should be done to confirm the settings of
the required seed rate and is done with the drill stationary and
level with the fan off.
The metering units must be set prior to filling with seed and
the bins are calibrated one-at-a-time.
Calibration Procedures
1 On the ProSeries head unit, navigate to the ‘RATE’
screen and enter the desired rate. Hit ‘ENTER’ to store
the value. Ignore max speed warnings at this stage.
2 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
3 Ensure that the metering unit is free from debris. Close
the trap-door and the bin emptying gate.
4 The metering unit should already be set. If not refer to
the pre-calibration flowchart on previous pages. Note
that it can be hard to adjust the settings once product is
in the bins.
5 Fill the appropriate bin. A minimum depth of 300mm is
required for calibration with normal seeds.
6 Place a suitable container under the metering unit of the
bin to be calibrated.
7 Open the trap door.
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 ProSeries Head Unit display 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.
