1.
Fill sprayer tan with enough water to perform
this test. Preferably 100 gallons or more. The
larger the volume of water used, the more
accurate the calibration will be .
2.
Start sprayer pump and turn booms
ON
. Run
enough water to purge all air from lines. Turn
booms
OFF
but leave pump running.
3.
Turn monitor rotary dial to the TOTAL VOLUME
position. Press and hold the button until the
display reads "0" (about 3 seconds).
4.
Turn booms
ON
and run a known amount*
of water (preferable 100 gallons or more) through
the flowmeter and out the nozzles.
5.
Turn booms
OFF
with Master ON/OFF Foot
Switch and compare the
monitor's TOTAL
VOLUME reading with the known amount of water
run. If the two amounts are the same, no fine
tuning is required. If the two amounts are
different, continue with the next step.
6.
Set the Parking Brake with the monitor still in
the TOTAL VOLUME position and enter calibration
(hold
CAL
button ). The display will alternate (at
about three second intervals) between the FLOW
CAL VALUE and the TOTAL VOLUME VALUE.
(The word "CAL" appears with the FLOW CAL
VALUE but not with the TOTAL VOLUME).
7.
When the TOTAL VOLUME value is displayed,
use the
+
or
-
button to adjust the VALUE to
match the amount of water run.
8.
Once the display begins alternating again, you
will notice that the FLOW CAL VALUE has
changed. The default FLOW CAL VALUE is 919.0.
If the TOTAL VOLUME VALUE is correct, write
down the new FLOW CAL VALUE. This is your
'fine tuned' calibration VALUE. Keep it for future
reference.
9.
Exit calibration by holding the
CAL
button or
driving the machine.
*The most accurate method to measure the
volume of water ran is to place a container under
EVERY nozzle and add together the amount from
each nozzle. This assures that 100 percent of the
water is collected and that all nozzles are spraying
equally. It is important to perform this procedure
at a flow rate similar to that which will be used in
the field.

FINE TUNING
FINE TUNING FLOWMETER SET-UP:
This procedure is used to verify and fine-tune the
flowmeter calibration. This procedure would be
repeated when the flowmeter installation has been
altered.
FINE TUNING SPEED SENSOR SET-UP:
1.
Verify proper tire pressure. Fill the spray tank
half full with clear water and fill the fresh water
tank.
2.
Select a straight tract of ground that is similar
to your actual turf conditions and as level as
possible. Mark a distance of at least 500 feet with
clear indicators at the beginning and end of the
course.
NOTE:
Using a course with a different ground
surface, such as a hard surface road, will result in
different readings than exact field conditions.
3.
Turn the Pump ON/OFF switch to OFF. Turn
the Master ON/OFF foot switch
OFF
(monitor will
be in HOLD mode). Turn the rotary dial to the
DISTANCE position. Push and hold the button
for 3 seconds to verify that the distance counter
is set to zero.
4.
Drive the machine through the measured
distance using the Master Boom switch to start
and stop the distance counter at the beginning
and end of the course. The displayed number
on the monitor should begin increasing when the
Foot Switch is pressed one time. Begin driving
the course well ahead of the start point and drive
past the end point. Stop in a level and safe area
to continue with this procedure.
5.
Compare the monitor's distance reading with
the actual distance driven (course distance). If
the two amounts are the same, no 'fine-tuning' is
required. If the two amounts are different,
continue with the next step.
6.
Set the Parking Brake with the monitor still at
the DISTANCE position, enter calibration mode
(hold
CAL
button). The display will alternate (at
about three second intervals) between the SPEED
CAL VALUE and the DISTANCE VALUE. The
word "CAL" appears with the SPEED CAL VALUE
but not with the DISTANCE VALUE.
7.
When the DISTANCE VALUE is displayed, use
the
+
and
-
buttons to adjust the VALUE to
match the actual distance driven.
8.
Once the display begins alternating again (after
64 seconds of not pushing any buttons), you will
notice that the SPEED CAL VALUE has changed.
The default SPEED CAL VALUE is .91. If the
DISTANCE VALUE is correct, write down the new
SPEED CAL VALUE. This is your 'fine tuned'
calibration value. Keep it for future reference.
9.
Exit calibration by holding the
CAL
button or
driving the machine.
