36HARDI® MUSTANG 3500 OPERATOR’S MANUALSpeed Cal / DistanceThis position is used to calibrate the speed transducer for accuratespeed, distance and area measurement. When this position isselected, the display will show the Distance Cal value and the distancetravelled. Either one may be used to calibrate for speed and distancemeasurement.

Determine the circumference of the sensor-mounted wheel, to the nearest tenth of an inch (thousandth of a meter),with the following method:Mark the tire with a piece of chalk and measure the distance travelled onthe ground for one complete revolution. See Figure 8.3. For improvedaccuracy, it is recommended to perform this function in field conditions,(with tank half-full), measure several revolutions, and take the average.Divide the measured revolution by the number of magnets installed.
