86 / SYSTEM CONFIGURATION
SPREADER CONSTANT
Determines how many pulses the application rate sensor produces per
volume of material discharged.
NUMBER (#) METER REVS
NOTE: If performing a Spreader
Calibration on a box type drill,
catch the output of a few seed
meters, average the weight
measured from these meters,
and multiply this average
weight by the total number of
meters on the drill. Enter this
weight for the Amount
Dispensed value.
Number of Meter Revolutions is the number of revolutions the meter will
turn during the calibration. This will constitute the length of the test. The
higher the number, the more accurate the calibration.
To perform the Spreader Constant Calibration:
1. Ensure that the system has performed a valve calibration.
2. Move the implement to the “raised” position.
3. Apply the tractor brakes and lock in the applied position.
4. Put the transmission in “park” or in a locked, neutral position.
5. Start the tractor and engage PTO if used to drive the hydraulic system.
6. Run the engine at normal operating speed until the hydraulic fluid is at
normal operating temperature.
7. Perform a fill disk until seeds are continuously being dispensed.
8. Place a container to catch the dispensed material.
9. Press the Start button.
10. Turn the master switch to the ON position.
11. The control will run the dispensing unit (meter/conveyor) at the
specified RPM for the specified number of meter revolutions and then
shut down automatically.
12. Weigh the material dispensed and enter the value into the Amount
Dispensed field.
13. The new spreader constant value will automatically calculate.
PULSE COUNT
A pulse count produced from the feedback sensor. This number is
informational only.
NEW SPREADER CONSTANT
After the spreader calibration is performed and the amount is entered, press
the Save button to accept the new constant.
AMOUNT DISPENSED
Enter the amount (Lbs/Kg) dispensed after performing the spreader
constant calibration. The amount dispensed number is used with pulse
count and density to calculate the new spreader constant.
