3.3 - Fine Tuning Calibration Factors
Calibration factors can be fine tuned in two ways. One - after metering a known quantity and
applying an adjustment formula. Two - by using the two tenths of a hectare test.
The two tenths of a hectare test runs the selected drive for 2/10
th
of a hectare while stationery.
Product can be caught and weighed to check bin calibration factors are correct.
3.3.1 - Metering a Known Quantity
1. Fill the bin with a pre-measured quantity.
2. Select an empty trip or reset the current trip.
3. After metering the pre-measured quantity, stop.
4. Press the “RECORDS” key. The “RECORDS” screen will be displayed.
5. Write down the weight value for the bin used to meter the known weight.
6. Apply the formula below to calculate a new calibration factor.
Formula
new calibration factor = displayed quantity ? old calibration factor ÷ actual quantity
7. Enter “TRP001 RATES” screen.
8. Press the softkey pointing at the pulses/kg (pulses/L) factor to highlight.
9. Use the arrow keys to enter the new calibration factor.
Note
Other bins can be operational while metering the pre-measured quantity using a separate bin. The
“RECORDS” screen displays quantities metered for each bin.
?? To increase product delivery, increase the calibration factor.
?? To decrease product delivery, decrease the calibration factor.
?? If bin runs out too fast, decrease the calibration factor.
