Sprayer Calibration
Sprayer calibration prepares your sprayer for operation
and diagnoses nozzle wear. This gives you optimum
performance from your nozzles and ensures accurate
application.
Equipment that may be needed:
•
Calibration Container
•
Great Plains Nozzle Tip Calculator:
832-038C - U.S. customary units (English), or
832-058C - Metric (English/Russian legends)
•
General calculator
•
Stopwatch or wristwatch with second hand.
Speed Calibration
Current TSF1080, TSF1090, TSF1280 & TSF1290
sprayers include a Raven SCS 450 controller as
standard equipment, and the SCS 450 requires a speed
sensing input, a new or existing wheel sensor or radar.
For a sprayer with the Raven SCS440 controller, perform
the speed calibration procedure from the Raven SCS
450 manual, then resume at
35 in this manual.
For a sprayer without a Raven controller, use the
following steps.
1.
Measure off a 200 foot (or 100 meter) course in the
area to be sprayed or in an area with similar surface
conditions.
2.
Select the engine throttle setting and gear that will be
used when spraying. Allow ample approach distance
to starting point so that tractor is at desired speed at
start marker. Allow ample overrun area so that
braking is not needed until exiting the course.
3.
Hold the speed as you approach the “start” marker,
and check the time required to travel through the
course to the “end” marker.
4.
Repeat the above procedure, and average the times
that were recorded. Use these equations to
determine the trial ground speed.
