automatically change to reflect the approximate speed required to achieve the
programmed target rate at the pressure selected. This gives an indication of the speed
range expected at the desired operating pressure range.
Use the
+
or keys to adjust this
value.
The console immediately determines
what the operating speed should be to
achieve the target application rate at this
pressure.
If the speed indicated is too high, a set
of smaller orifices or Micro-Tubes is
needed.
If the speed indicated is too low, a set of
larger orifices or Micro-Tubes is needed.
Press the
