When you switch from a low sowing dose to a high dose, for example from
3kg/ha to 100kg/ha, use the following procedure:
1. Open the dispenser to a raised position.
2. Start the calibration procedure, distribute a suitable quantity of product and
enter the weight obtained. The error will be substantial but press ENTER to
correct the calibration factor and continue (see Fig. 15).
3. The programme now needs the application dose (see Section 2.3).
4. Repeat the calibration procedure again, and this time the error should be low.
Accept the error and begin to sow.
When you switch from a high sowing dose to a low dose, for example from
100kg/ha to 3kg/ha, use the following procedure:
1. Open the dispenser to a lowered position.
2.
Start the calibration procedure, distribute a suitable quantity of product and
enter the weight obtained. If a manual calibration button is used, distribute a
small quantity of product and enter the weight. The error will be substantial
but press ENTER to correct the calibration factor and continue (see Fig. 15).
3. The programme now needs the application dose (see Section 2.3).
4. Repeat the calibration procedure again, and this time the error should be low.
Accept the error and begin to sow.
B.8.2 ‘CALIBRATION NUDGE’ – Adjusts the calibration factor
The ‘CALIBRATION nudge’ procedure allows you to adjust the existing
calibration factor without having to rerun the test with the bucket.
1. First, note the quantity of product displayed in the PARTIAL counter on the
INFO screen. This is the theoretical quantity that the instrument has calculated.
From the SETTINGS screen, either press (Calibration Verification), or
(Sower SETTINGS).
If the console is configured for two products, select the product to calibrate (fig.
10).
Likewise, if the console is configured for two dispensers, select the right or left
side (fig. 11).
2. On each screen, press to select the ‘CALIBRATION Nudge’ screen (fig.
16).
