2.5 SETTING BOOM WIDTHS
The Mid-Tech TASC Control Console is designed to automatically compensate for changes in the swath width, caused
by activating or deactivating separate sections of a multi-section spray boom. For the console to automatically respond to
changes in swath width, it is necessary for the operator to set the individual boom section lengths into the console. Use
the following procedure to define the boom lengths to the console.
A. Set the Console 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 in inches.
B. As each boom position appears on the display, use the INC/DEC Switch to set the display to the appropriate
number of inches (meters) covered by that boom. Repeat for each section.
NOTE: Individual boom widths are entered in inches. The control console converts the total boom width to feet
when it is switched back to the Operate Mode and the booms are turned on.
C. Set all unused boom sections (up to a total of nine) to a width of zero “0” inches. This insures that an accidental
boom switch ON does not affect the control console.
D. Let the boom width display cycle through the boom sections until it shows “Boom C”. As the width of “C” is
displayed, it can be changed with the INC/DEC switch. This value is used by the control console to determine
the operating speed for the injection pumps during calibration sequences (as long as none of the boom switches
are turned ON). This value should be the normal operating width of the entire sprayer, in inches (meters).
E. The individual boom section widths are now established. Turn all boom switches to the ON position and return
to the OPERATE Mode, the new total boom width is displayed in feet (meters). If this does not agree with your
total sprayer width, check the individual boom widths (steps B and C).
2.6 FLOW METER CALIBRATION
TASC must be calibrated for the flowmeter being used. The calibration number required by TASC is the actual number of
electrical pulses per gallon generated by the flowmeter for each gallon of liquid that passes through the flowmeter.
Flowmeters are calibrated for water at the factory. This number is to be considered an initial value. The actual flowmeter
calibration number for your system may differ due to plumbing variations or other factors. If you have any doubts as to the
accuracy of the flowmeter calibration number, a field calibration/catch test should be performed using the actual
carrier solution. This is particularly important if you are pre-mixing chemical with the carrier.
