F. Make sure there is enough liquid in the main tank to do the test; start the main carrier pump; rotate the display
selector switch to TEST SPEED; turn ON the boom switch. Allow the sprayer to discharge until the desired
amount has been pumped; turn OFF the boom switches.
G. Rotate the display selector switch to CARRIER, TOTAL APPLIED. If the total shown on the console agrees
with the total discharge actually measured, no further action is necessary. The flowmeter is already calibrated.
H. If the indicated volume pumped does not agree with the actual volume pumped, calculate a corrected calibration
number as follows:
(INDICATED AMOUNT / MEASURED AMOUNT) X OLD CAL. # = NEW CAL. #
I. Set the mode selector to SET-UP and correct the calibration number using the INC/DEC switch. Return the mode
selector to OPERATE and the amount displayed should now match the amount measured. The flowmeter is now
calibrated.
J. Write this number down for future reference. This is the number to use for these specific conditions (material and
sprayer configuration).
K. Further fine tuning of the calibration can be done based on field spraying experience. If liquid is consistently left
over after spraying a known number of acres, adjust the calibration number up slightly. If there is consistently
too little liquid to cover the desired acres, adjust the calibration number down slightly.

2.7 DISTANCE CALIBRATION, GROUND SPEED SENSOR
2.7.1 GENERAL CONSIDERATIONS AND INITIAL CALIBRATION NUMBERS
It is important to field calibrate the distance sensor to insure optimum accuracy! The distance calibration must be
periodically checked. This is especially important if the sensor has come loose or been repositioned (Radar Sensor), or if
the tires have been changed (Wheel and Speedometer Sensor).
Use the following initial calibration settings to get started. For the radar this number will be pretty close. For the wheel
speed sensor and the speedometer sensor the adjustment to this initial calibration number may be very large, depending
on the configuration of the vehicle.
Dj RADAR - 1000 MID-TECH COMPACT RADAR - 779
WHEEL SENSOR & SPEEDOMETER SENSOR - 3500
A. Set TASC switches to the following settings:
Power ON
Mode Selector SET-UP
Display Selector DISTANCE
The display now shows the current distance calibration value.
If the measured amount is more than the indicated amount,
the calibration number should decrease. If the measured
amount is less than the indicated amount, the calibration
number should increase.
