HARDI ® MUSTANG 3500 OPERATOR’S MANUAL
APPENDIX A: FINE-TUNING SPEED CAL /
DISTANCE CALIBRATION VALUE
This procedure is used to verify the calibration of the system. In order
to achieve accurate measurements, each step in this fine tuning
procedure should be performed as precisely as possible.
Preparation:
• Once the system is fully installed and calibrated, select a straight
tract of ground that is similar to your actual field conditions and as
level as possible.
NOTE: Using a course with a different ground surface, such
as a hard-surface road, will result in different readings than
exact field conditions.
• Measure a distance of 1000 feet (300 meters). Clearly mark the
beginning and end points with flags or something highly visible to
the operator.
Procedure:
1. Place the console in HOLD. The display will read HOLD. Turn the
rotary dial to the “SPEED/CAL 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.
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 (e.g. door handle, mirror, step). You
should begin to drive the course well ahead of the starting flag and
drive past the ending flag, using the AUTO/MAN/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 console in MAN 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
console in HOLD when the marker on the vehicle passes the
ending flag to stop the distance counting function. Stop the vehicle
