FMH Calibration Report
A producer must calibrate within 3% accuracy to meet the RMA calibration requirement in order to use precision production data for a crop insurance claim. Records of these calibration measurements are required when validating a claim.
Reminder: You must calibrate at the start of harvest!
Only reference Machine Speed field for multi-point calibrations
Single Point or Self-Calibrating: FINAL calibration or calibration check must be within 3.0% at each speed
Multi-Point: FINAL calibration check for each speed used must be within 3.0%
Instructions
Complete weight calibrations when you begin harvesting each new crop. The previously recorded data will not be adjusted to reflect the new calibration.
IMPORTANT: Refer to your manufacturer specifications prior to completing the Calibration Checklist!
Verification Checklist
- Temperature Calibration
- Complete this step once annually.
- Do not perform temperature calibration when sensor is in direct sunlight.
- Mass Flow Vibration Calibration
- Calibrate to manufacturer specifications.
- Complete this step for each harvested crop.
- This calibration will be saved in the combine setup under the identified crop. Be sure to select the current crop.
- Moisture Sensor Correction
- Complete this step once per season for each harvested crop.
- Temperature calibration should be completed before this correction. Be sure to set the moisture correction value to 0.0 before beginning the process.
- Weight Calibration/Accuracy Check
- RMA requires the monitor displayed weight be within 3.0% accuracy. To verify the accuracy of the monitor, check the machine displayed weight against another scale source and track on the verification report on the reverse side of this form. If the checked weight is not within the 3% tolerance, continue to weigh loads and track them until the monitor is within the tolerance. Once you are within the tolerance, no further accuracy checks are required for that crop for the remainder of the year.
- Difference Percentage Calculation for Weight Accuracy Check. To determine accuracy, you must calculate the difference percentage. Use the following calculation on the reverse side of this form: 100 x (Machine-Displayed Weight - Scale-Measured Weight) / Scale-Measured Weight = Difference %
