INLINE/BYPASS:
Set
to BYPASS (harness
reverses the wires
so the servo will run
correctly).
NOTE: if used on a
Micro-Trak NH3 system, it must be set to Bypass.
SETTING TOOL BAR WIDTH:
In order to accurately
measure the pounds (kg) of “N” applied per acre (hectare), it
is important to determine the correct “working” width. The
“working” width is the width of ground being affected by
any operation. This should be measured to the nearest inch
(millimeter).
Your “working” width will be the number of knives times
the knife spacing in inches (meters). For example, if you
have 8 knives spaced at 30 inches, the working width is 240
inches.
See Illustration below.
TEST SPEED:
Not used
for anhydrous ammonia
application.

SPEED CAL:
This position is used to calibrate the speed
sensor for ac cu rate speed and dis tance measurement.
When this position is selected, the display will show the
SPEED CAL value along with “CAL” on the display. See
Speed Calibration
section (page 26) for
details. To fine-tune
the SPEED CAL, see
Fine Tuning SPEED CAL
for NH3 on page 56.

Your Micro-Trak NH3 flowmeter has been tested at the
factory and assigned a “NH3 Cal” value (pulses/lb N) to
make it operate properly with the MT-3405F II console.
This number is printed on the plastic tag attached to the
flowmeter.
See below.
This is a starting point only. The
value must be fine tuned.
See Fine-Tuning Flowmeter
Calibration for NH3 on page 57.
When entering the flow
cal value, take note of decimal point placement.
WIDTH:
To calibrate the implement width the nurse tank
must NOT be connected to the system.
Turn on Boom 1
switch and put the RUN/
HOLD switch in RUN. Use
the “+” and “-” switches to
adjust the number to the
working width of your tool
bar in inches (thousandths
of meters).

EXITING CALIBRATION:
To save the changes you made,
you MUST exit calibration by pressing and holding the CAL
