Radar

A radar speed sensor will be indicated with an "r" on
the display e.g.
The "r" will automatically appear during the auto
calibration process when the console has determined
that a radar is being used. When manually entering
a radar calibration number the "r" must be turned on
by pushing the Auto/Man key. With this key you can
toggle between radar or wheel sensor. The calibration

value itself is adjusted with the

and

keys.

Manual Calculation

To manually calculate the proper value for Wheel Speed Sensor pulses, you need to know
the circumference of the wheel to which the sensor is mounted. It can be measured by
marking the tire and measuring the distance covered as that mark makes one full revolution.

Then use the following formula:

248

600

Inch

nce

Wheel

rotation

Pulses

Use the

keys to adjust the value. Press the key to validate the value and

advance to the next programming step.

Note: The wheel calibration should be repeated if you are changing to another wheel

diameter.

Simulated Speed

If you enter 0 in the speed calibration step, then the console always works with a simulated
speed. This simulated speed can be used to test out the sprayer at stand still.

The simulated speed feature allows you to check out the sprayer at a certain speed without
actually moving the sprayer. This can be done prior to any spraying activity. The simulated

speed value can be changed with the

and

keys when the speed is shown on the

display in normal working mode.
