2.9 SETTING BOOM WIDTHS
TASC automatically compensates for changes in the swath width, caused by changing active boom sections. To do
this, it is necessary for the operator to define the boom widths using the following procedure.
A. Set the Console switches to the following positions;
Power ON
Mode Selector SET-UP
Display Selector WIDTH
All Boom Switches (external) OFF
The display cycles through each boom position and displays its current width.
B. As each boom position appears on the display, use the INC/DEC switch to set the display to the number of
inches (meters) covered by that boom section.
C. Set all unused boom sections (up to a total of nine) to a width of zero “0” inches (meters). This ensures that
an accidental boom switch ON signal does not affect application rates.
D. Finally, let the boom width display cycle through the boom sections until it shows Boom C. As the width of
C is displayed, it can also be changed with the INC/DEC switch. This value is used by the console to control
the operating rate for each channel during calibration operations where the boom switches are normally
OFF. This value is normally set to the total operating width of the entire applicator, in inches (meters).
E. When the boom widths are set turn all the live booms ON and return to the OPERATE mode, the new total
boom width is displayed in feet (meters). If this does not agree with your total boom width, check the
individual boom widths again, (steps B and C).
2.10 DISTANCE CALIBRATION
The ground speed sensor must be calibrated to ensure accurate application rates. This calibration should be periodi-
cally checked, especially if the sensor has been moved or the tires have been changed.
2.10.1 INITIAL CALIBRATION SETTINGS
The following values will be close. Use them for the initial settings so you get an initial reading of distance during
the calibration procedure.
NOTE: IT IS IMPORTANT TO FIELD CALIBRATE THE GROUND SPEED SENSOR TO INSURE OPTIMUM
ACCURACY.
MID-TECH COMPACT RADAR - 779 DICKEY- john RADAR - 1000
WHEEL SENSOR - 3500 SPEEDOMETER SENSOR - 3500
A. Use the following switch settings to enter the initial distance calibration number.
Power ON
Mode selector SET-UP
Display selector DISTANCE
B. The INC/DEC switch is used to set the initial number.
2.10.2 DISTANCE CALIBRATION PROCEDURE
A. Fill the machine 1/2 full of product to approximate average load conditions.
B. Measure a known distance of 400 feet (150 meters) or more along a field or roadway. It should be in an easy
