6. Once the calibration is complete, drive the vehicle and compare
the vehicle’s speedometer to the DriveRight 600’s speed display.
Be aware that the DriveRight 600 responds to changes in speed faster
than most vehicles’ speedometers. To accurately compare, you must
drive steadily at a speed for a short time.
7. If necessary, “fine tune” the calibration by pressing PLUS or
MINUS.
Each time you press PLUS or MINUS, the DriveRight 600 speed
reading adjusts up or down. Depending on the speed of the vehicle
and the calibration, you may or may not see a change in the speed
reading in the calibration screen each time you press the button.
NOTE: Pressing and holding PLUS or MINUS down
increases the rate at which the DriveRight 600
adjusts the speed reading.
8. Continue to Press PLUS or MINUS until the DriveRight 600’s
speed reading agrees with your vehicle’s speedometer at a variety
of speeds.
9. When finished calibrating, press and hold MODE until you return
to the data screen.
When you finish fine-tuning, press MODE to exit the calibration
screen. All information will be automatically saved. 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.
Calibration Using the Odometer
In order to calibrate using the odometer, you must compare a dis-
tance reading taken from your vehicle’s odometer to the DriveRight
600 and adjust the DriveRight 600 to match the vehicle’s odometer.
Depending on how far you drive in order to calibrate the unit, this
can result in an extremely accurate calibration.
NOTE: We recommend that you drive a minimum of 32km (20 miles)
when calibrating the unit.
Your vehicle’s speedometer and odometer may not be perfectly
linked. If they differ and you calibrate your DriveRight 600 using
the vehicle’s odometer, you may notice a discrepancy between the
DriveRight 600’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 6.
2. Reset your vehicle’s trip meter to zero or make a note of the
odometer reading.
