Float Calibration

The float calibration procedure must be performed when a header is initially hooked up if the ground pressure (float) mode of operation will be used. This procedure calibrates the header pressure sensor.

Prepare Header for Calibration:

  • Turn key switch to "RUN" position
  • Attach header to combine and connect header harness
  • Move machine onto a level surface
  • Raise header completely
