If you did replace the monitor or flow sensor and you forgot to change

any of these values, you must set all new loads to a different grain type

(e.g., CORN to SPECIAL CORN) and calibrate the monitor for grain

weight and moisture for that grain type. To change the voltage, box, or

sensor calibration values, use the top-right UP or DOWN ARROW keys.

11.The scale factor number has been changed.

Solution: If you change the scale factor during the harvest season, you

will lose your calibration accuracy and will have to recalibrate by

changing to different grain types and entering new calibration loads. The

scale factor should be set to the value that is on the Initial Calibration

Sheet, unless:

• you saved your old calibration loads (from the previous year) that

were harvested under a different scale factor setting.

• you were satisfied with the calibration accuracy you have been

getting and do not want to change anything.

12.The flow sensor or the stainless steel deflector plate is installed

backwards and the grain is not hitting the flow sensor.

Solution: On some combines, the flow sensor or the curved stainless

steel deflector plate can be installed backwards. Take the flow sensor out

and examine how it was installed. If your yield monitor kit was shipped

with an elevator deflector plate, examine how it is installed. Refer to the

installation instructions for the correct installation.

Install the curved stainless deflector with the curve against the back of

the elevator housing where the paddles are bringing up the grain. Install

the flow sensor so that the grain coming off of the paddles hits the impact

plate (plate with curve at one end that attaches to the black load cell) at

approximately a 90 degree angle (for Deere 9x00 and Claas combines,

the grain will hit the impact plate at an angle of 25 to 30 degrees)
