Standard Calibration Procedure

IMPORTANT: Before calibrating be sure that combine grain tank and unloading auger tube are empty. Be sure that wagon or truck hauling grain away from combine is empty.

Yield monitor system can be accurate only if the operator follows correct calibration procedures.

The following procedures should be performed at maximum ground speed which the operator expects to run in this crop and condition, and in an area that is reasonably level and of uniform yield.

NOTE: Message with the following information may appear on the screen: "Low Cal Flow Comp NOT required". If this message appears, flow rate during calibration was very low. Therefore, it is neither necessary nor possible to perform optional Low Flow Compensation procedure. Standard Calibration procedure is sufficient.

1. Press letter button next to "Calibration Mode" to select the desired Calibration.

2. Press letter button next to "Start/Stop". Display will change to: "Yield Calibration is Running".

3. Begin harvesting. Weight displayed in the "Harvested Weight" cell should increase while harvesting.

4. Harvest known amount of grain (i.e. grain tank full, truck load, wagon load, etc.).

5. When known load is completed, stop machine and allow all harvested grain to enter grain tank.

6. Press letter button next to "Stop" to stop the calibration. Display will change to "Yield Calibration is Stopped".

IMPORTANT: Be sure to empty grain tank completely and be certain all grain is on one vehicle (wagon or truck).

7. Have known amount of grain weighed. While waiting for scale ticket to return, you may continue by pressing "RUN".

8. When scale ticket returns to combine, go to Yield Calibration Page.

9. Press letter button next to "Scale Weight" to change weight value.

10. Using numeric keypad, input Net Weight of Grain from scale ticket.

IMPORTANT: Standard calibration procedure will not change data already saved. After changes are made, all harvest information collected from that point on will reflect the changes.

NOTE: If scale ticket weight is more than 50% higher or lower than displayed weight, the system will NOT allow entry of scale weight. It is recommended that you review harvesting procedures and verify vehicle hauling grain away from combine is also following correct procedures. At that time, repeat calibration procedures.

11. Press letter button next to "Scale Weight" to ENTER new value. Calibration Factor will change automatically when grain weight is entered.
