8.
Use the combine display or a voltmeter (if measuring the
sensor manually) to measure the voltage range. If using a
voltmeter, check sensor (A) voltage between pin 2 (ground)
and pin 3 (signal). The range should be
•
For Case and New Holland combines: 0.7
–
1.1 V

10. If adjustment is required, loosen hardware (A) and rotate
sensor (B) until the voltage is in the correct range.
11. Once sensor adjustment is complete, torque the hardware
to 2.1 Nm (22 lbf·in).
