854 Sprayer Control
Speed.Sensor.Calibration
NOTE: During Speed Sensor Calibration, the 854
automatically senses whether a Wheel
Speed or Radar Speed Sensor is being
used.
Proximity/Magnetic Pulses
The speed sensor must be calibrated to provide the
proper speed and area readings. The value for this
step is the number of pulses generated by the speed
sensor in 300 feet (100 meters).

Automatic Calibration
NOTES: When the Automatic Calibration Mode is
activated, “CAL” is displayed on the lower
right of the display.
It is best to perform the automatic speed
calibration process at least twice and use the
average of the speed calibration numbers.
The auto speed calibration process should
take place with the sprayer tank 1/2 full.
• Mark off a distance of exactly 300 feet (100
meters).
• Press and hold the PLUS and MINUS
keys simultaneously for 3 seconds to activate
the auto calibration mode.
• Start driving toward the start point of the 300
feet (100 meter) course.
• As the starting point is crossed, press the PLUS
keys once to begin the calibration process.
• The 854 will count the pulses generated while
the course is driven.
• As the ending point is crossed, press the PLUS
key once. The number displayed on the
screen is the speed calibration number.
• If the console determines that a radar speed
sensor is connected, it will display “rAd” on the
lower left part of the display.

Once the calibration number has been determined, it
must be entered into the console.
• Press the PROGRAM and PLUS keys
simultaneously to put the console into Radar
Mode. When the control console is in Radar
Mode, it will display “rAd” in the lower part of
the console display.
• Use the PLUS or MINUS keys to adjust
the value.
• Pressing the AUTO/MAN key will reset the
speed calibration to the default value.
• Once the correct vale has been entered, press
the PROGRAM key to validate the value and
advance to the next step.
