| Problem: |
Probably Cause: |
Solution: |
| Yield is inaccurate after calibration |
- Inconsistent harvesting during calibration run
- Sensors are dirty or damaged
- Error while entering values and units on Calibration Completion page
|
- Calibration run best practice — complete in consistent/average part of field with minimal turns
- Click sensor out of mounting base and inspect lenses
- Confirm correct units were entered on Calibration Completion page of app.
- Make sure test weight was entered properly
|
| Bushels are incorrect but weight is correct |
- Test weight set incorrectly (lbs/bu, kg/hL)
|
- Go to Add/Edit crops page from app main menu, select crop type and edit. Confirm test weight values and units are correct
|
| Average yield is incorrect but live yield is correct |
- Yield Monitor is calculating area incorrectly
- If elevator is running at partial throttle while not collecting yield, Yield Monitor will be confused
|
- Confirm sensor calibration is correct. Yield Monitor should not be counting area while not harvesting
|
Yield readings display 0 while
harvesting |
- Issues with GPS
- Sensor calibration not completed properly
- Sensor fault
- In rare cases, sensors are placed too close to the elevator chain and the chain is blocking sensors during sensor calibration process
|
- Confirm you have a ground speed—if no speed, unplug external antenna to see if speed appears. If so, contact support for a new antenna
- Rerun sensor calibration from the Device Calibration page of the App menu (must be done while stationary with no crop in elevator, at full throttle)
- Visually inspect sensors and confirm the green status LEDS are on and there is power to the monitor. The receiver should have a blinking or solid yellow light indicating it sees the other sensor and elevator is stationary
- Redrill. Contact support to determine diagnosis and for advice on sensor location before drilling
|
| Area is incorrect |
- Sensor calibration not completed or incorrect
- Moving without harvesting while at partial throttle and with thresher engaged
|
- Rerun sensor calibration from the Device Calibration page of the App menu (must be done while stationary with no crop in elevator, at full throttle)
- Try to ensure throttle is at 100% while driving with header up or threshing clutch is disengaged (this won’t affect your field averages for your maps. ie the accuracy of your yield data)
|
Yield does not display until well
into the swath/pass |
- Processing time delay set incorrectly
|
- Time delay should be around12 seconds. Edit the processing time delay on the Device Calibration page. Count the new delay by measuring time from first crop entering header to just before crop enters the grain tank
|
Yield values disappear after a
sensor calibration |
- In rare cases, sensors are placed too close to the elevator chain and the chain is blocking sensors during sensor calibration process
|
- Contact support to determine diagnosis. Rare cases may require redrilling. Contact support for advice on sensor location before drilling.
|
| Yield values appear on live screen when driving empty across field |
- If separator clutch is not engaged, a paddle may be bouncing in the line of sight of the sensor
- Driving with separator clutch engaged but at partial throttle
|
- This will not affect the accuracy of your yield maps
- Disengage separator clutch or operate at full throttle
|
| Dry live-yield/volume/weight are inaccurate but wet are accurate |
- Dry moisture or current moisture reading is incorrect
|
- Dry values are calculated from the current wet moisture down to the dry (market) moisture. To change market moisture, go to Add/Edit crops page from app main menu, select crop type and edit. Confirm dry (market) moisture value is correct
|
| Yield values inaccurate when only harvesting a partial pass |
- Yield Monitor does not account for partial swaths in field
|
- Follow best practice by trying to keep consistently full swaths. Partial swaths will be automatically corrected in the Web App.
