For best results also verify that vibration calibration has been performed for each crop.

Achieving High Accuracy Calibrations:

• NOTE: Do NOT turn around on end rows or crossing waterways while preforming calibration.
  Keep a consistent flow rate within the calibration load (monitor flow rate on VisionTrak™ performance monitor and adjust ground speed accordingly).
• Calibrate loads at different flow rates (know what each calibration load characteristic is in case one must be deleted or more loads must be added).
• Keep all calibration loads approximately the same weight.

• Load ID (B) - shows current load ID number during calibration.
• NOTE: A minimum 1,360 kg (3,000 lb.) of crop must be harvested for calibration to be accepted.
  Estimated Weight (C) - shows combine collected weight for load collected by mass flow system during calibration.

  Load Identification (A) - shows collected load ID numbers for future references.

---

• Estimated Weight (B) - shows weight for load collected by mass flow system during calibration.
• Actual Weight (C) - shows operator entered load weight.
• Percent Error (D) - shows percentage of difference between estimated weight and actual weight.

  Formula:

  Error % = 100 x (Estimated - Actual) ÷ Actual

  Example:

  0.5% = 100 x (17919 - 17829) ÷ 17829

• Limited Accuracy - user calibration procedure has not been performed. System defaults to a fixed internal calibration value which may not be adequate for different machine and field conditions.
• Single Point Calibration - user performed calibration procedure and collected one to three calibration loads. Usually adequate for fields where yields are fairly consistent, which allows consistent flow rate.
• Multi-Point Calibration - user performed calibration procedure and collected four or more calibration loads. Calibration accuracy is better for fields where there are large varying yield conditions, where flow rate is not kept consistent. NOTE: Refer to Single Point Yield Calibration Or Multi-Point Yield Calibration later in this section for further information.

NOTE: Entering calibration factors is mainly to help transfer calibration values between multiple machines within the same field. It is not advisable to make up entirely new calibrations.

• Use default calibration to restore factory calibration values in case of entering errors that are not correctable.
• Entering calibration number C11 while performing a single point calibration forces a linear (single point) calibration even if the previous calibration was multi-point calibration.
• Adjusting calibration number C11 during a multi-point calibration proportionally adjusts all other calibration numbers C1—C10 based on calibration number C11 adjustment. A nonlinear calibration characteristic is preserved, but with a different intensity. Example, if calibration number C11 is increased by 10% (0.1), calibration numbers C1—C10 also increase by 10%.
• If non-proportional adjustments are needed (multi-point only), all calibration numbers must be adjusted individually.

• Single Point (B) - calibration can be modified by adjusting calibration number C11.
• Multi-Point (C) - calibration can be modified by adjusting calibration number C11 only or adjusting C11 and then adjusting all 10 calibration numbers.
• Default (D) - restores factory initial calibration numbers.
