DELTA RATE ADJUSTMENT: The Target Spray rate you
entered during calibration represents the amount of chemical
you typically want to apply. Under certain field conditions
you may want to change application rates.
The DELTA you entered during calibration allows you to
change applications rates by flipping the “+/-” toggle switch.
Each time you flip to “-”, the Target Rate will decrease by the
DELTA amount. Each time you flip to “+”, the Target Rate
will increase by DELTA. The DELTA is active only in AUTO
and with rotary switch a SPRAY RATE or % ERROR.
EXAMPLE
DELTA = 1.00 AND target rate set at 8.00.
With master in AUTO and rotary at SPRAY RATE or
% ERROR, Flipping to “-” and releasing will show a new
Target Rate, 7.00 for 2 seconds and return to actual
SPRAY RATE or % ERROR. Another “-” will drop the
Target Rate from 7.00 to 6.00. Flipping “+” will raise
Target Rate from 6.00 to 7.0.
NOTE: After using DELTA, the “New Target Rate” will
remain saved in memory until you give another DELTA or
enter calibrate and change your Target Application Rate.
WARNING LIGHT: The Warning Light will come on in
AUTO if application error exceeds 10%. If the light stays on
in AUTO, consult the troubleshooting section of this manual.
The Warning Light will also stay on in the CAL mode.
PRESSURE GAUGE: While the pressure gauge itself has
no bearing on the operation of the MT-3000, pressure is
very important and should not be overlooked. Make sure
your Spray Rate, Flow Rate, Speed and Pressure all coincide
with the Spray Tip Manufacturer’s Charts. Learn where your
pressure normally runs and watch for any changes. A change
in pressure normally runs and watch for any changes. A
change in pressure may indicate a problem somewhere in
the system. Make sure the pressure change is not simply due
to a change in Target Sprat Rate or Speed.
CAUTION: Do not connect pressure gauge to liquid
fertilizer.
