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.

IMPORTANT: Threshing Clearance Calibration should not be completed with round bar concave covers installed. An incorrect zero position may result.

• Threshing Clearance Calibration - Perform calibration when control unit LC1, threshing clearance sensor, or associated components are replace/adjusted.

• 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.

• 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 is added to or removed from head.

• 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.

NOTE: When prompted during self-leveling shoe calibration to level chaffer and 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.

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

• Smart Feed Rate Handle Calibration (If Equipped) - Perform calibration when control unit VCM, handle position sensor are replaced/adjusted.

• Smart Feed Rate Valve Calibration (If Equipped) - Perform calibration when control unit VCM, forward solenoid, or reverse solenoid has been replaced.

  NOTE: Moisture sensor must be calibrated if any of the following conditions exist:

  · Moisture sensor readings inaccurate.

  · Moisture sensor shows "moisture unmeasurable" warnings.

  · Moisture sensor HMM or related components were replaced.

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

NOTE: Mass flow sensor must be calibrated every year to achieve accurate grain weight measurements.

Standard calibration must be performed in every crop that is harvested.

Low Flow calibration must be performed to obtain improved levels of accuracy in situations where large variations in grain flow rates occur. Refer to Yield Calibration in CommandCenter Display Screens section for more information.

• Yield Calibration (If Equipped) - Perform calibration when control unit HMM or associated components are replaced/adjusted.

• Service Hours Calibration - Reset Service Hours.

• 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.
  • First time each header is connected to combine.
