Speed Cal / Distance
This position is used to calibrate the speed transducer for accurate
speed, distance and area measurement. When this position is
selected, the display will show the Distance Cal value and the distance
travelled. Either one may be used to calibrate for speed and distance
measurement. (If using radar, enter factory calibration number.)

Determining Distance/Cal Factor (UPP)
For the console to calculate the correct speed and measure distance
and area accurately, the circumference of the sensor-equipped wheel
must be determined. 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 on
the ground for one complete revolution. See Figure 8.3. For improved
accuracy, 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.
