OPERATOR’S MANUAL
To establish a Ground Speed Constant:
1.
Accurately measure one mile marking the start and finish points.
Markers should be visible from the cab while driving past. Alternatively,
two highway mileage markers can be used.
2.
At the Ground Speed Calibration screen (F8), press C to begin
calibration.
3.
Drive to the start of the course at a minimum speed of 5 mph (8Km/hr).
4.
When even with the start marker, press S on the keyboard. The
calibration begins as the vehicle is moving.
5.
Drive at normal operating speed.
NOTE: For better accuracy, it is
recommended to slow down at
the second marker so reaction
time is better when pressing “S”
to stop.
6.
At the finish marker, press C to complete the calibration.
7.
Press S to save the value, press R to restart the calibration or press
Esc to abort the calibration.
8.
To ensure accuracy, repeat the calibration procedure three times and
average the results. Enter the average value.
9.
Record the ground speed constant on the Calibration Data Records
sheets at the rear of this manual.
