OPERATOR’S MANUAL
NOTE: Calibration Data Sheets are
available in back of this manual
to record constants.
3. With the vehicle stationary, engage the hydraulic system.
4. Increase engine RPMs to normal operating range.
5. Press “R” to begin test and to run the conveyor/auger. Several steps
display during calculations before the System Response Done screen
appears. The number in the middle of the screen shows the counts
accumulating from the APR sensor. If a count is not recorded and
stays on “0”, stop the test and check the application rate sensor.
6. When a sufficient amount of material has dispensed, press “S” to stop
the system. A screen appears indicating the previous spreader
constant and the sensor counts accumulated during the current run.
7. Perform the next step while the screen waits for the results.
8. If using a vehicle scale, reweigh the truck and calculate the amount of
material dispensed in pounds.
9. Enter that number into the console and press “D” when finished. The
new spreader constant is now stored and displayed on the calibration
screen and on the appropriate configuration screen for this material.
10. For maximum accuracy, repeat the entire procedure at least three
times.
11. Average the results and enter the average as the final spreader
constant.
12. Record the material’s spreader constants on the Calibration Data
Records sheets at the rear of this manual.
13. Repeat this procedure for each granular material used.
