Calibration Procedures - When to Calibrate

This list shows all possible calibrations. Depending on machine options and header types, listing shown might not match calibration menu shown on display.

NOTE: Error codes show on display if a problem exists during a calibration procedure. Conditions causing error must be corrected before continuing calibration.

• Amber Flashers- Perform calibration when control unit RC1, Amber Flasher bulbs, or associated components are replaced/adjusted.

• Corn Head Deck Plate Spacing Calibration - Perform calibration when control unit LC1 or deck plate position sensor or associated components are replaced/adjusted.

• Feeder House Speed Calibration - Perform calibration;
  • If control unit LC1 has been replaced.
  • First time each header is connected to combine.
  • If attachments of significant weight are added to or removed from header.

• Feeder House Tilt Calibration (If Equipped) - Perform calibration;
  • If control unit LC1 has been replaced.
  • If lateral tilt sensor or associated components are replaced/adjusted.
  • Before connecting header to combine.

• Feeder House Tilt Speed Calibration (If Equipped) - Perform calibration;
  • If lateral tilt sensor or associated components are replaced/adjusted.
  • Before connecting header or first time header is connected to combine.

• Header Calibration - Perform calibration;
  • If control unit LC1 has been replaced.
  • If a header height control sensor or associated components are replaced/adjusted.
  • First time each header is connected to combine.

• NOTE: Mass Flow Vibration calibration must be performed when changing headers and in every crop that is harvested.
  Mass Flow Vibration Calibration (If Equipped) - Perform calibration when control unit AYM or associated components are replaced/adjusted.

• Moisture Sensor Temperature (If Equipped) - Perform calibration when control unit AYM or associated components are replaced/adjusted.

• NOTE: When prompted during self-leveling shoe calibration to level chaffer/sieve, use switches on side of machine to level bays.
  Self-Leveling Shoe Calibration (If Equipped) - Perform calibration when control unit LC2 or chaffer/sieve actuator has been replaced/adjusted or bays are not level.

• Chaffer Opening Calibration - Perform calibration when control unit LC2 or chaffer actuator has been replaced/adjusted or louver openings are out of adjustment.

• Sieve Opening Calibration - Perform calibration when control unit LC2 or sieve actuator has been replaced/adjusted or louver openings are out of adjustment.

• IMPORTANT: Calibration should not be completed with round bar concave covers installed. An incorrect zero position will result.

  Threshing Clearance Calibration - Perform calibration when control unit LC2, threshing clearance sensor, or associated components are replace/adjusted.

• Unloading Auger Engage Calibration - Perform calibration when control unit RC2, unloading auger belt or associated components are replaced/adjusted.

• NOTE: Yield calibration must be performed every year and in every crop that is harvested to achieve accurate grain weight measurements.

  Refer to Yield Calibration in CommandCenter Display Screens section for more information.

  
  Yield Calibration (If Equipped) - Perform calibration when control unit AYM or associated components are replaced/adjusted.
  • Limited Accuracy - user calibration procedure has not been performed. System defaults to a fixed internal calibration value which is not adjustable.
  • Medium Accuracy - user has collected and selected one to three loads. System uses these values to adjust the internal calibration value.
  • Highest Accuracy - user has collected and selected a minimum of four calibration loads. System uses these values to adjust the internal calibration value. NOTE: 13 load identification numbers can be saved before memory is full and a load identification number must be deleted.
