• Make sure your memory card, thumb drive, etc., is installed into your yield monitor and turn on your combine and yield monitor. Make sure there is proper communication between the card and the display monitor. Usually an error message will appear on the display indicating there is no communication with the card.
  • Check to see if you are receiving a good differential correction signal (DGPS).
  • Raise and lower the header to make sure the stop height switch operates correctly. Some monitors are equipped with a manual switch that turns on and off data collection to your monitor. You may have to adjust the header height switch to accommodate the preferences of different operators during harvest.
  • Make sure to set row width according to number of rows for a row-crop header and the appropriate width of a cutting platform header.
  • Engage the separator and observe the elevator speed on the monitor to see if it is working.
  • Put the combine in drive and make sure the ground-speed indicator is working.
  • Before calibrating loads make sure you will be using accurate scales to weigh the grain. Certified scales or calibrated weigh wagons are recommended. If you are using weigh wagons it is recommended to leave the wagon in one location in the field. Moving the weigh wagon through a field causes it to shake and bounce which can throw off the calibration of the weigh wagon. Make sure you are also using the same scales throughout calibration.
