When to Calibrate

The following calibration procedures (machine settings) must be performed before first use:

  • Header Width Calibration

    - For accurate area counter calculations.

    - For non John Deere headers a special harness kit is required; see your John Deere dealer.

  • Header Calibration Automatic Header Control - hdr

    - After attaching a new or another John Deere header.

  • Machine Harvesting Threshold Calibration - ACAL

    - For accurate area counter calculations.

    - For cutting height (for example sunflower harvesting).

  • Float Calibration - FLO

    - After attaching new John Deere header.

    - After attaching John Deere cutting platform without sensors in skid plates.

  • Concave Sensor Zero Calibration - conc

    - After servicing.

  • Deck Plate (optional) Sensor Calibration - dEc

    - For John Deere corn heads only.

The following calibration procedures (machine settings) must be performed when replacing any of the sensors:

  • Header Calibration Automatic Header Control - hdr
  • HEADERTRAK Angle Sensor Calibration - tiLt
  • Concave Sensor Zero Calibration - conc
  • Tailings Monitor Calibration
  • Deck Plate (optional) Sensor Calibration - dEc

The following calibration procedures (machine settings) can be performed as required:

  • Field Area Counter Clear Calibration - ACF
  • Field Total Area Counter Clear Calibration - ACFt
  • Clock Calibration - clc
  • Straw Chopper Deflector Vane Angle Calibration - ICAL
  • Remote Shoe Adjust User Calibration - CHA - SIE or PrE

    - In case an actuator has been manually adjusted.

    - In case the position of your element (chaffer, sieve or precleaner) and display do not match.

  • Contact your dealer for a Remote Shoe Adjust Factory Calibration - OP5

    - In case an actuator, an element (chaffer, sieve or precleaner) or a control unit has been replaced.

    - In case the position of your element (chaffer, sieve or precleaner) and display do not match and the user calibration did not fix the problem.

  • CLIMATRAK calibration

    - In case of erratic functioning.

    - In case a potentiometer has been replaced

  • Unloading auger swing time calibration

If any errors occur during the calibration procedures, service codes will be displayed on the triple display tachometer.

NOTE: The condition causing the error must be corrected before the calibration can be continued.
