Bu/Ac or lbs/Ac Yield
too high or low (cont.)
The Sensor Cal, Box
Cal, or Voltage Cal
number has changed.
To view the Sensor Calibration number, press
MENU, SETUP, and VEHICLE keys. To view
Box Cal, and the Voltage Cal number, press
MENU, SETUP and CONSOLE keys. Check each
value against the Initial Calibration Sheet. None
of the values should change unless the monitor or
flow sensor was changed. If the monitor or flow
sensor was changed and these values not changed,
all new loads must be set to a different grain type
(e.g., CORN to CORN 3) and calibrate the monitor
for grain weight and moisture for that grain type.
To change the voltage, box or sensor calibration
values, highlight the selection and then press EDIT
to change the settings, using the up/down arrows
to change the values.
The scale factor
number has changed.
To view the Scale Factor setting, press MENU,
SETUP, and VEHICLE keys. If the scale factor
changed during harvest calibration accuracy will
be lost. Recalibrate by changing to a different
grain type and entering new calibration loads. The
scale factor should be set to the value on the Initial
Calibration Sheet, Unless the current calibration
accuracy is satisfactory.
The grain is not
hitting the flow
sensor because the
flow sensor or
stainless steel
deflector plate is
installed backwards
See your Combine Installation Instructions to
ensure flow sensor and deflector plate are installed
correctly.
Stainless steel
deflector plate worn
or damaged
Inspect the deflector plate for excessive ware,
holes or washboard (ripple) appearance. Replace
deflector if any of the above conditions are
present. Change grain types calibrate weight again.
