PROCEDURE:
1. Put enough water in the sprayer tank to perform
this test. (Preferably 100 gallons or more. The
larger the volume of water used, the more
accurate will be the calibration.)
2. Start sprayer pump and turn on booms. Run
enough water to purge all air from lines. Turn off
booms but leave pump running.
3. Place monitor in Hold mode and turn console
rotary selector to the CALIBRATION FLOW
position. Press and hold the RESET button until
the display reads 0 (about 3 seconds).
4. Switch the monitor to Run Mode and turn on
booms and run a known amount* of water
(preferable 100 gallons or more) through the
flowmeter and out the nozzles.
5. Turn off booms and switch the monitor to Hold
mode. Compare the consoles CALIBRATION
FLOW 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. With the console in the FLOWMETER
CALIBRATION position, enter calibration (console
in HOLD, hold CAL until red light comes on; about
three seconds). The display will alternate (at about
three second intervals) between the flowmeter
calibration value and the CALIBRATION FLOW
value. (To tell which is which, watch for the word
CAL on display. It will be present with the
flowmeter calibration value but not with the
CALIBRATION FLOW value).
7. When the CALIBRATION FLOW value is
displayed, use the + or - button to adjust the
value to match the amount of water run.

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.
*The most accurate method to measure the
volume of water run 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 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.
3. Turn the Pump ON/OFF Switch to OFF. Place
the monitor in HOLD mode with the RUN/HOLD
button. Turn the rotary dial to the CALIBRATION
DISTANCE position. Push and hold the RESET
button for 3 seconds to verify that the distance
counter is set to zero.
4. Drive the vehicle through the measured
distance using the RUN/HOLD Button 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
monitor goes to RUN mode. 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. Space the monitor to the SPEED CAL position
and enter calibration mode (monitor in hold, hold
CAL until red light comes on; about three
seconds). The display will alternate (at abut three
second intervals) between the SPEED CAL value
and the CALIBRATION DISTANCE value. (When
the words CAL and HOLD appear, the number
displayed is the SPEED CAL value. When only
the word HOLD appears, that is the CALIBRATION
DISTANCE value.)
7. When the CALIBRATION DISTANCE value is
displayed, use the "+" and "-" keys to adjust the
value to match the actual distance driven.
8. Once the display again begins alternating (after
64 seconds of not pushing any keys), you will
notice that the SPEED CAL value has changed.
If the calibration 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 CAL until the red
light goes out (about three seconds).
8. Once the display again begins alternating, you
will notice that the flowmeter calibration value has
changed. If the CALIBRATION FLOW value is
correct, write down the new flowmeter calibration
value. This is your fine tuned calibration value.
Keep it for future reference.
9. Exit calibration by holding CAL until the
consoles red light goes out (about three
seconds).
