This procedure is used to verify the speed/distance calibration.
In order to achieve accurate measurements, each step in this
fine tuning procedure should be performed as precisely as
possible.
CAUTION: Do not perform this procedure with the nurse
tank connected to the system.
PREPARATION
•
Once the system is fully installed and calibrated, se lect a
straight tract of ground that is similar to your ac tu al field
conditions and as level as pos si ble.
NOTE: Us ing a course with a different ground sur face,
such as a hard-surface road, will re sult in dif fer ent
read ings than exact field con di tions.
• Measure a distance of 1000 feet (500 meters). Clear ly
mark the beginning and end points with flags or some-
thing highly visible to the operator.
PROCEDURE
1. With the console turned ON, place the Controller 1
switch in the MASTER HOLD position. The HOLD icon
will be displayed. Turn the rotary dial to the “DISTANCE”
position. Be sure the display shows 0. If not, reset the
distance counter by pressing and holding “RESET” until
the display returns to 0 (approximately one second).
The word CLEAr will be displayed when reset is pressed.
Make sure all Ch1 boom switches are OFF. Make sure
Ch2 switch is set to OFF.
2. You are now ready to drive the measured course. Pick a
location on the vehicle to use as a marker for starting and
stopping the distance counting function (door handle,
mirror, step, etc.). You should begin driving the course
well ahead of the starting flag and drive past the ending
flag, using the Auto/Man/Master Hold switch to start and
stop the counting function. It is not recommended to
start from a dead stop at the starting flag and stop at the
ending flag.
3. Place the Ch1 switch in MAN (or AUTO) when the
marker on the vehicle passes the starting flag to activate
the distance counting function. The console display
numbers will increase, adding to the distance total as
you drive. Drive the pre-measured course and place the
Controller 1 switch in the MASTER HOLD position, when
the marker on the vehicle passes the ending flag, to
stop the distance counting function. The console display
should read “HOLD”.
See Illustration to the right.
Stop
the vehicle in a level and safe area and continue with this
procedure.
4. With the rotary dial still at DISTANCE (SPEED CAL), press
and hold the “CAL” key for one second. Once the con-
sole is in “CAL,” CAL and the speed calibration value
will be displayed. Momentarily press CAL and the word
CAL will begin to flash and the distance travelled will be
displayed.
See Illustration below.
5. When the display shows distance (“CAL” is flashing),
ver i fy wheth er the number displayed is the ex act
dis tance you drove (with in +/- 1 - 2 %). If not, press the
“+” or “-” key to ad just the fig ure to match the dis tance
you ac tu al ly drove. If the display reads too high, use the
“-” key to lower the dis played value. If the display reads
too low, use the “+” key to raise the displayed value.
6. When the number shown on the display match es
(as close ly as possible)
the ac tu al dis tance driv en, you
have ar rived at the cor rect cal i bra tion val ue. If you
can not adjust the displayed distance to exactly match
the actual dis tance driven, adjust the figure as close
as possible to the actual distance. You may check the
calibration number by momentarily pressing CAL. The
word CAL and the SPEED CAL number will appear. Exit
“CAL” by pressing “CAL” for one second.
The speed sen sor is now calibrated. To verify proper
calibration, repeat the procedure a sec ond time. Write
down the new speed calibration number and keep it in a
safe place. If the cal i bra tion values are ever accidentally
changed, you can simply re-en ter this num ber.
