Spot Treatment Calibration:

  1. Measure and mark off 18.5 ft. X 18.5 ft. in target area.
  2. Spray area uniformly with water and record number of seconds it takes.
  3. Spray water into container for this amount of time.
  4. Amount of water collected in container in fluid ounces equals spray volume in gallons per acre.
  5. Boomless Sprayer Calibration
  6. Measure effective swath width.
  7. Determine calibration course by using the following: (Divide 5460 square feet (1/8 acre) by the swath width in feet.) Example: calibration distance for 32 foot swath width = 5460 divided by 32 = 171 feet.
  8. Drive this course in the gear and rpm you will use when actually spraying. Record the time in seconds. Do this twice and average the time.
  9. Park and maintain the same rpm, pressure.
  10. Turn on the sprayer and use a trash bag and bucket to catch the water for exactly the same number of seconds required to drive the calibration course.
