The following two steps are calculation or informational steps only. They have no effect
on the application or operation of the console.
Known Speed Calculation
Adjust the speed value to the desired application speed. The pressure value
automatically adjusts to the approximate pressure required to apply the desired
application rate at the speed selected. This allows the opportunity to be sure the
application values are in the range expected prior to the actual application.
Use the
+
or keys to adjust
the indicated speed to a value
that you will be traveling at.
The console immediately
calculates what the pressure
should be to maintain the target
application rate at this speed.
If the pressure is too high,
substitute a larger set of orifices
or Micro-Tubes, or slow down.
If the pressure is too low, substitute a smaller set of orifices or Micro-
Tubes, or speed up.
