Yield Monitor troubleshooting
The display is not mapping.
1. Make sure the display Header Height setting is lower than John Deere's setting.
2. Ensure that the crop type is the same.
3. The machine must be in normal harvesting operation mode.
The display stops mapping periodically through the field.
Cause: The header could be raising and lowering past the setting for Stop Logging Header Height.
Action: Increase the Header Height setting on the display.
Display yield information does not match John Deere's information.
Cause: Different crop types may be selected.
Action: Verify the crop types match in both displays.
The display shows a major jump or extremely different weight values from
those shown on the John Deere monitor.
Cause: The Stop Head Height setting is lower than what the John Deere monitor shows. The John
Deere monitor could be logging more data than the FM-1000 integrated display logs, therefore
showing a larger value.
Action: Set the Head Height to 100% on the John Deere display.
