PF3000 Troubleshooting
Ag Leader Technology Harvest Mode
April 2002 6-5
Problem Cause Solution
Bu/Ac or lbs/Ac Yield
too high or low (cont.) 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:
•
Old calibration loads were saved from the
previous year under a different scale factor setting.
•
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 PF3000 installation instructions to ensure
flow sensor and deflector plate are installed
correctly.
“Expand Grain
Below Dry” is set to
YES. To view this setting, press MENU, SETUP and
VEHICLE keys. If this setting is YES, any grain
harvested below the dry moisture value will be
increased to the dry moisture value before the yield
is calculated. If the average moisture of the grain
is below the Dry Moisture value, the yield in bu/ac
will be higher than that calculated from the
elevator. This occurs in soybeans where the
moisture is often below the Dry Moisture value.
To accurately compare the yield of different
soybean varieties, increase the bushels to the Dry
Moisture value. Use the up/down arrow keys to
select “Expand Grain Below Dry” and press EDIT
key. Use the up down arrow keys to select NO and
press ACCEPT key.
