7.6 Calibrating Header Sensors

When a new header is attached to the windrower, the header's sensors must be calibrated using the cab display module
(CDM) so that their output can be correctly interpreted by the windrower control module (WCM).

7.6.1 Calibrating Header Height Sensor

The header height sensor can be calibrated by accessing the cab display module's (CDM) WINDROWER SETUP menu. The
calibration procedure must be completed for the sensor to be correctly calibrated.
NOTE:
• The header must be attached to the windrower to perform this procedure. The CDM automatically selects the header
profile based on the type of attached header.
• The engine must be running to perform this procedure.
