Grain Monitor Calibration
 
document Q: How should I perform the weight calibrations?
Question: How should I perform the weight calibrations? Answer: It is very important to perform at least four (preferably six) calibration loads for each grain that you will be harvesting. Each load should be harvested at a different grain flow rate by varying ground speed or the width of cut. This allows for a good calibration at varying flow rates. Calibration loads should be similar in size and be a minimum of 3,000 pounds.

document Q: Do I have to perform the weight calibrations at the beginning of harvest?
Question: Do I have to perform the weight calibrations at the beginning of harvest? Answer: No. You may calibrate the monitor anytime during the harvest season for weight. When you perform the weight calibration it will adjust all previously harvested loads.

document Q: How often do I need to perform calibrations?
Question: How often do I need to perform calibrations? Answer: You must calibrate once for each grain type harvested. The recommendation for weight calibration is six loads, harvested at various ground speeds. As the harvest season progresses, check the accuracy of the monitor and enter one or two more calibration loads if needed.

document Q: Do I need to recalibrate every time I change from harvesting one type of grain to another?
Question: During the harvest season, I switch between harvesting corn and soybeans. Do I need to recalibrate every time I change grain types? Answer: No (and yes.) You have to calibrated the display once for each particular grain type (Corn, Soybeans, Wheat) in the monitor, the calibrations remain attached to that grain type for the entire season. You are able to move from one crop to another as harvest conditions dictate.

document Q: What calibrations need to be performed before the combine is used?
Question: What calibrations need to be performed before the combine is used? Answer: Vibration, Header Stop Height, Distance, and Temperature all need to be calibrated before operation.

document Q: How can I get accurate readings all season?
Question: Towards the end of harvest, my yield monitor was not as accurate as it was when I first calibrated it. How can I get accurate readings all season? Answer: As your crop dries down in the field, you harvest faster and you can get a higher amount of grain flow through your combine. Your original calibration may not have taken those higher flows into account, because the combine's grain flow capacity could have been limited by high grain moisture. If you enter a few more actual load weights...

document Harvest Calibration C Values Resetting Due to Poor Vibration Calibration
This article walks through the process of resetting a flow sensor that has a poor vibration calibration and is causing the calibration values to reset. Symptoms experienced I’ve calibrated the system and see flow and yield but after power cycling my yield becomes inaccurate. When I check my calibration “C numbers” the values look incorrect values should be ascending in value starting with C1 C1 should be negative and all other values should be positive C11 should be around 3000 V1...
