estimated calibration value and then fine-tune the calibration.
Any number between 10 and 15 (255 mm to 380 mm) is a
good starting value.
NOTE: For fine-tuning the SPEED CAL value, see Appendix B
on page 44.
Illustration 15
To determine SPEED CAL, measure the distance of
one complete wheel revolution and divide by the
number of magnets installed.
For the console to calculate the correct speed and measure
distanceaccurately,thecircumferenceofthesensor-equipped
wheel must be entered. Determine the circumference of the
sensor-mounted wheel to the nearest tenth of an inch (tenth
of a centimeter) with the following method:
METHOD
Mark the tire with a piece of chalk and measure the distance
traveled on the ground for one complete revolution. See
Illustration. For improved accuracy, it is recommended that
you perform this function in field conditions, measure several
revolutions, and take the average.
Divide the measured revolution by the number of magnets
installed to get your starting SPEED CAL calibration value.
Once calibration of the system is complete, this number
should be fine-tuned for optimum accuracy.
For fine-tuning the SPEED CAL value, see Appendix B on page 44.

EXITING CALIBRATION: Upon completion of the calibra-
tion process, exit calibration by pressing and holding the
CAL button until the RED warning light turns off (one sec-

application, confirm that the system is set up to do the
job that you want it to. Please refer to Pre-Field System
Checkout to confirm calibration settings, nozzle selection
and overall system performance. NOTE: You must exit CAL
to save any changes.

Valve Response Speed: Allows adjustment of response
to “tune” the system for use with very fast or slow valves.
For example, if using a ball valve that takes several seconds
to open or close in manual mode, and the system responds
sluggishly, use the “+” button
to adjust the valve response
number to 1, 2, or 3. The range
of adjustment is -4 to 3, factory
setting is -1. NOTE: exercise
caution when increasing the
valveresponse speed. Ifusing
a relatively fast valve (1-3
seconds open-to-close), the system may become unstable
with higher valve response speed numbers entered.

Fill Tank Size: If using the Tank feature, this setting can
be used to enter the volume of the tank. Use the “+” and
“-” buttons to choose OFF or any value from 1-65,535. Then
when the tank is filled,
the tank counter can be
reset to full by simply
turning the rotary switch
to the TANK position
and pressing the “+”
button. Depending on
the “UNITS” setting, the
TANK SIZE units will be either gallons or liters. If “material”
is set to NH3, the Tank Size will be in lbs. or kg. Anhydrous

Pre-Field System Checkout described on pages 39-40 prior
to beginning any field operations.
Press the ON/OFF button to turn the console on. After
displaying the hours of operation and software version, the
console will start normal operating mode.
The MT-3405F™ II can be operated in Manual (MAN) or
Automatic (AUTO) mode. In either mode, the right-hand
display will always show the Application Rate (except
when in HOLD or when displaying error messages, see
Troubleshooting section starting on page 33). The left hand
display will show data as selected by the rotary switch.
Manual Operation
The manual mode is used when the operator wants to
manually control the servo valve using the “+” and “-” keys,
and thus the application rate. The application rate (gal/acre
or liter/hec) will vary depending on ground speed. Use the
AUTO/MAN button to select MANual mode (“MAN” icon will
be displayed).
IN HOLD: If the console is in HOLD, or if all Boom Valves are
OFF, the “+” and “-” buttons will not control the servo valve
unless the rotary switch is in the VOLUME/MINUTE position.
In that position only, the servo valve can be adjusted without
any boom valves on. This can be useful for system pressure
tests, etc.
IN RUN, WITH SPEED SIGNAL: If the system is in RUN,
with at least one boom valve ON and there is a speed signal,
the “+” and “-” buttons can be used to adjust the servo valve
with the rotary switch in any position except TANK, VOLUME,
and AREA and the application rate can be monitored on the
right-hand display.
IN RUN, NO SPEED SIGNAL: If there is no speed signal,
“no SPEEd” will flash in the right-hand display and the
Application Rate will be invalid. The “+” and “-” buttons will
adjust the servo valve if the rotary switch is in the VOLUME/
MINUTE position, and the flow rate (GPM or LPM) can be
monitored.
Turn rotary dial to display desired readout.

the servo valve to maintain the desired application rate
(GPS/LPH) when the vehicle speed changes or when booms
are turned on or off. Press the AUTO/MAN button to select
AUTOMATIC mode; the AUTO icon will appear in the display.
To operate the system in AUTOMATIC mode, turn on the
desired booms, toggle the RUN/HOLD switch to RUN, and
drive. IMPORTANT NOTE: In AUTO mode, when no speed
signal is available, the system automatically turns all
booms off. “no SPEEd” will flash in the right-hand display
until the vehicle starts moving, then the console will turn the
booms on and the Application Rate will be displayed in the
right-hand display. The system will automatically adjust the
servo valve to maintain the calibrated TARGET RATE (GPA/LPH).
ON-THE-GO “DELTA” RATE ADJUSTMENTS (ADJUST
RATE): To adjust the target application rate on-the-go,
each time the “+” or “-” buttons are pressed, the TARGET
RATE will be increased or decreased by the amount of the
ADJUST RATE which was entered in calibration. Example:

GPA, pressing the “+” key once will increase the target rate
from 10.0 to 11.0. The rate display will momentarily show the
new target rate of 11.0 and then show the actual application
rate. Pressing the “-” key once will decrease the target from
11.0 to 10.0. NOTE: When you “DELTA” the target rate, the
display will momentarily show you the new target rate
and then resume showing the actual application rate. The
new target rate is maintained until further adjustments
are made using the “DELTA” feature or calibration changes
occur, or if the unit is turned off. Important: to use the
DELTA feature, the console must be in AUTOMATIC mode
and the rotary switch can be in any position except TANK,
VOLUME, or AREA.
IN HOLD: If the system is in AUTO mode and in HOLD or
all booms are off, the “+” and “-” buttons will adjust the
TARGET RATE with the rotary switch in any position except
TANK, VOLUME or AREA; CAUTION: we recommend that
the rotary switch is in the RATE position, because that is
the only position where the new TARGET RATE is displayed
while in HOLD. In RATE position, the left-hand display will
momentarily display the new TARGET RATE, then will revert
to .00, because all the boom valves are off so there is no
product being applied.

the TANK position, the left-hand display shows the amount
remaining in the tank. If a FILL TANK SIZE (tank full) number
has been entered in Special Calibration, the “AUTO FILL”
feature is active; this feature allows the TANK counter to
be quickly reset to a full tank amount by simply pressing
the “+” button with the rotary switch in the TANK position.
The “-” button can be used to reduce the tank counter, but
any press of the “+” will set the counter to the calibrated
FILL TANK SIZE value.
If no TANK VALUE has been entered in calibration, the tank
counter can still be used, but the counter must be manually
adjusted when filled, by pressing and holding the “+” button
until the desired value is reached.
