Calculate the Rate Cal Value
Determine the application rate pounds/acre [kg/ha] at which the chemical is to be applied. This figure is used
as the Rate Cal value. Be sure to consult with the equipment manual to verify that the gate opening is capable
of applying at that rate.
Note:
The Spreader Constant value must be recalculated every time the gate opening dimensions are
changed.
Digit Description Range Range Definition
Valve Backlash
Controls the time of the first correction pulse
after a change in correction direction is
detected (INC to DEC, or DEC to INC)
1 - 9
1 = Short Pulse
9 = Long Pulse
Valve Speed
Controls the response time of the control valve
motor.
