place to maneuver the vehicle. The longer the distance, the more accurate the test.
C. Drive to the starting point and STOP. Make sure all booms are OFF. Turn ON the TASC power switch.
D. Turn the display selector to DISTANCE and put the mode selector in SET-UP. The TASC displays the
current distance calibration number. Record this number for reference.
E. Put the mode selector switch to the OPERATE position and use the DEC switch to set the accumulated
distance reading to ZERO. (If the console shows a distance being accumulated while the vehicle is station-
ary, the radar is vibrating. Change engine RPM or install dampening material under the radar mounting
bracket to stop the vibration.)
F. Drive the vehicle to the other end of the measured distance using a speed of five to ten miles per hour (ten to
fifteen kilometrs per hour). Stop at the end marker.
G. The TASC displays the accumulated distance. Compare the accumulated distance to the measured distance,
if they are the same, calibration is complete. If they are different, correct as follows:
H. Calculate the new calibration number using the formula:
Use the INC/DEC switch to change the distance calibration number, in the SET-UP mode, until
the displayed distance in the OPERATE mode is the same as the actual distance.

2.11 CALIBRATION OF CHANNEL C
Channel C is typically a granular channel. It may be necessary to adjust the calibration number in the TASC console
to ensure an accurate output from the machine. If applying a granular product the calibration number represents the
number of sensor pulses per cubic foot of material discharged. If applying a liquid product the calibration number
represents the number of sensor pulses per gallon of material discharged.
The conveyor must be calibrated whenever there are changes to the discharge gate openings. (NOTE: Other
factors, such as moisture content, granule size, granule shape, etc., may also affect this constant.)
THE CALIBRATION PROCEDURE IS SIMPLE. IT IS IMPORTANT TO CALIBRATE FOR THE MATERIAL
AND GATE OPENINGS YOU ARE USING. Be sure you have entered the proper PRODUCT DENSITY (SEE
2.4.2).
A. Use the following switch settings.
Power ON
Mode selector SET-UP
Display selector CARRIER, VOL. APPLIED
Booms ON (if channel is in split drive)
Channel C Product switch ALT. RATE
The display shows the current calibration number. Record for reference. Turn the booms OFF.
B. Weigh the machine and load. Back up to a location where you can safely collect the discharged material.
(ACTUAL DISTANCE ÷ DISPLAYED DISTANCE) X CALIBRATION NUMBER = NEW
CALIBRATION NUMBER. (If the distance shown on the console is greater than the actual
distance, the calibration number will decrease.
