8. Continue to Press "+" or "-" until the DriveRight agrees with your
vehicle’s speedometer at a variety of speeds.
9. When finished calibrating, press and hold MODE down until you
return to the data screen.
DO NOT PRESS AND HOLD
SET/CLEAR
in an effort to save the fine-
tuned calibration! If you press and hold
SET/CLEAR
, the unit completely
resets the calibration number. When you finish fine-tuning, press
MODE
to
exit the calibration screen. All information will be automatically saved.
Calibration Using The Odometer
In order to calibrate using the odometer, you must measure the distance you drive
on your vehicle’s odometer and compare that to the distance recorded by the
DriveRight 130AL. Then adjust the DriveRight 130AL until it reads the same dis-
tance as the vehicle. Depending on how far you drive in order to calibrate the unit,
this can result in an extremely accurate calibration.
We recommend that you drive a minimum of 20 miles when calibrating the unit.
NOTE:
Your vehicle’s speedometer and odometer may not be perfectly linked. If they
differ and you calibrate your DriveRight 130AL using the vehicle’s odome-
ter, you may notice a discrepancy between the DriveRight 130AL’s speed
readings and the vehicle’s speedometer.
1. Obtain a rough calibration, using the speedometer as described in
“Calibration Using the Speedometer” on page 8.
2. After obtaining a rough calibration, reset your vehicle’s trip meter to
zero or make a note of the odometer reading.
3. Make a note of the distance travelled reading displayed in the Cur-
rent Readings screen.
4. Drive your vehicle for at least 20 miles (32 km).
The further you drive, the more accurate your calibration.
5. When you finish driving, determine how many miles/kilometers the
DriveRight recorded by subtracting the distance travelled reading
you noted prior to driving the vehicle (step 3)to the miles/kilome-
ters displayed when you finished.
6. Compare your vehicle’s trip meter reading to the distance travelled
reading on the DriveRight 130AL.
At this point, what you will need to do is increase or decrease the distance
measured by the DriveRight 130AL until it agrees with your vehicle’s odome-
ter reading. This is accomplished from the calibration screen.
