FMH Precision Crop Insurance Solutions™
Yield Monitor Calibration for Crop Insurance
Proper monitor calibration is essential when using precision ag data for crop insurance reporting and claims. Learn about RMA calibration requirements, download calibration reports, and securely upload your records in the FMH Policyholder Center.
Why Calibration Matters
3%
RMA Accuracy Requirement
For precision production data to be used for a crop insurance claim, the USDA Risk Management Agency requires yield monitor calibration to be within 3% accuracy.
Records of calibration measurements are required when validating a claim.
How It Works
How to Submit Your Calibration Report
Once you’ve completed your calibration:
02
Sign In
Log into your FMH Policyholder Center (PHC) account or the FMH Mobile app. Navigate to Precision Solutions > Calibration Report.
03
Upload Your Report
Upload your completed report to your PHC account for secure storage and easy adjuster access in the event of a claim. Your agent can also access this record through your account with your permission.
Calibration Requirements by Equipment Type
Single Point Calibration
The last calibration needs to be within 3% accuracy. If a farmer has been within 3% for most of the harvest, but the final calibration is outside this threshold, the farmer will no longer qualify for a precision claim.
Multi-Point Calibration
Each calibration speed must meet the 3% accuracy requirement. At least five calibration speeds should be recorded for production data to qualify for a precision claim.
Self-Calibrating Systems
The farmer must verify the system is calibrating to under the 3% threshold. They must capture the wet weight for a load or region and compare to their scale source per machine.
Calibration Report
What Information Should Your Calibration Report Include?
To meet RMA calibration requirements, record the following during each yield monitor calibration, regardless of equipment type.
Calibration Date and Time
Crop Harvested
Field Name
Scale Source
Flow Rates
Machine Measured Weight
Scale Measured Weight
Positive or Negative Weight Difference
Average Crop Moisture Percent
Vibration and Moisture Calibration

accurate calibration results.

Start Empty
Before calibrating, be sure the grain tank and auger tube are completely empty. Be sure that the weigh wagon or truck hauling grain away from the combine is also empty.
Calibrate Moisture
Calibrate moisture sensors when harvest season is underway.
Calibrate Each Crop
Initially calibrate the mass flow sensor at the beginning of the season for each crop, then calibrate as needed.
Watch Changing Conditions
Re-calibrate as crop conditions change significantly over the season (e.g., crop dry-down, test weight, variety/hybrid change, crop field conditions change).
Use Proper Load Sizes
Calibration loads should be similar in size to the manufacturer's selected weight.
Use Consistent Scales
Use the same weight scales throughout the calibration process.

Frequently Asked Questions
What do I do with my calibration reports when I don’t have a claim?
We recommend uploading a copy of your calibration reports to your FMH Policyholder Center (PHC) account. All your precision records are then easily available in the event of an APH review.
My combine(s) harvest fields for multiple insurance entities. Do I need separate calibration reports for each entity?
No. Calibration reports can be shared between entities. The same report can be uploaded via the FMH Policyholder Center for each account. Please remember that final calibration for each combine needs to be within 3% accuracy for RMA requirements.
I am already documenting my weighed and farm-stored production. Why do I need to provide harvest wet-weight maps and calibration records instead?
When combines are calibrated accurately, they are more reliable when compared to measuring several bins, bags, or other farm-stored structures. The harvest wet-weight maps and calibration records fulfill RMA verification requirements.
